In an age where parenting advice is readily available at our fingertips, it’s easy to get lost in the myriad of modern methodologies that dictate how we raise our children. In his recent discussion with Chris Williamson, Dr. Paul Turke—a pediatrician and evolutionary anthropologist—offers a thought-provoking perspective on the drastic shifts in parenting practices over the past millennium. He challenges the conventional routines that dominate contemporary parenting, advocating for a return to more instinctual and natural approaches that mimic the ways our ancestors nurtured their offspring. This blog post will sift through the claims made by Dr. Turke, examining their validity and context, to determine whether modern parenting has indeed strayed from what could be the most beneficial path for our children. Join us as we delve into the debate, uncovering truths and misconceptions in the world of parenting today.

[00:00:00,000]: How might child rearing look different if parents were educated in evolutionary theory [00:00:07,519]: Well I think quite a few ways [00:00:10,920]: Probably the biggest one in one of the big themes in my book is that we used to live embedded in kinship networks [00:00:21,840]: So we had lots of different helpers contributors helping us to raise our children [00:00:31,200]: You know there are situations now where one parent usually a mother gets stuck with three kids in a home [00:00:41,099]: And it’s very different from how things used to work back in the day [00:00:46,540]: And it puts a lot of stress on everybody children but parents parents also [00:00:52,080]: So that’s a big thing [00:00:56,159]: Kids when they would go out to play and run around they would be in sort of mixed age groups [00:01:02,939]: So they would have if you were a three year old you’d have a seven year old there to learn from and you might be helping a two year old [00:01:13,760]: And so the sort of the independent child stuff would be different [00:01:19,660]: So those are two of the big ways that we’ve lived and we live now sort of in a mismatched environment [00:01:29,160]: What about what does that say about broken homes or un intact homes increasing single parents step parents [00:01:39,120]: What are the implications of that when it comes to child development [00:01:43,379]: Yeah I think it puts a lot of stress on children [00:01:48,639]: It also you know the human brain the child’s brain is very malleable very undeveloped when baby first appears on the scene [00:02:00,900]: And when we change the environment the early environment that children are reared under we sort of miss I think some of the cues that lead to normal development [00:02:17,600]: Now humans if anything you know we’re flexible [00:02:20,300]: We can adapt to a lot of different things [00:02:22,619]: So it’s not the end of the world [00:02:25,699]: But if we’re trying to optimize you know we’re sort of off the optimum if we’re under those sorts of stressful situations [00:02:35,839]: And I think that has implications for happiness and healthiness and you know just emotional well being that sort of thing [00:02:49,619]: And even things like ADHD potentially the more spectrum y things on the autism spectrum all of that can be affected I think by this mismatch environment stressful broken homes the step parents like you say [00:03:08,679]: So I don’t know if you want to go into it but there was a group of evolutionary psychologists Martin Daly and Margo Wilson who did early work on step parenting [00:03:21,600]: And you know they found that step parents tend to be—I mean most step parents are great [00:03:29,899]: You know of course they step in they help they’re wonderful [00:03:33,059]: But statistically there’s more likelihood of abuse or neglect coming from the step parent [00:03:38,360]: You know it’s the old Cinderella thing [00:03:41,720]: And so you know the more our environment is altered from what we used to have where there were always three or four people [00:03:53,179]: So if grandma was a bad apple you know there were other people to step in [00:03:57,059]: But if it’s just a broken home and just one mom or one dad you know that can increase the amount of abuse and things like that that go on [00:04:12,539]: So that was very influential early work in evolutionary psychology [00:04:17,859]: And some people got upset about it where they’re saying oh my God because it’s natural does that mean it’s okay for step parents to abuse kids [00:04:25,220]: And you know of course that doesn’t make sense [00:04:28,339]: That’s a naturalistic fallacy [00:04:31,459]: And yeah no it’s almost the opposite [00:04:36,299]: It’s the idea that you know hey if you’re going to be a step parent just be forewarned that there’s some going to be emotional challenges for you [00:04:46,299]: And it could be a little bit harder than you know and that sort of thing [00:04:50,019]: So we would hope that would remedy the situation not excuse it [00:04:54,679]: Yeah it’s be extra vigilant if you’re a step parent [00:04:58,619]: You know this is going to be tough [00:04:59,899]: Raising kids is tough [00:05:01,459]: And one of the ways that the toughness of raising kids gets ameliorated is by them being your genetic progeny [00:05:08,720]: So you’re like they’re crying again for the seventh night in a row but it’s my cry [00:05:13,200]: But if it’s just the person that you’re in love with’s progeny’s cry there’s a lot less motivation to be there and you might get more frustrated so on and so forth [00:05:22,720]: And yeah I think it’s a 100x increase in child mortality when there’s one non biological parent in the household [00:05:30,299]: So some of the outcomes I mean the base rate for that’s quite let’s not say that it’s making a massive difference but it’s a sufficiently significant difference that it’s something everyone should be aware of [00:05:38,720]: You mentioned there about grandparents [00:05:42,820]: What’s the evolutionary role of grandparents [00:05:46,119]: Why does it matter for raising kids back then and sort of what’s the implication for today [00:05:51,700]: Yeah well I mean I think it’s huge [00:05:56,359]: Grandparents well first of all when we used to live about as long as the other apes you know up to about 6 million years ago and the way we sort of extended our reproductive viability most likely especially for grandmothers if menopause was ancient as we think it was it was by caring for children [00:06:19,480]: So reproducing indirectly taking care of the kids we’ve already reproduced and helping them [00:06:26,179]: And one of the big ways we help them is by taking care of their children [00:06:30,839]: And so there’s been this long running history of grandparents and babies and children and grandchildren interacting and helping one another [00:06:44,899]: And I think it’s good for both sets [00:06:50,459]: When I was younger doing fieldwork I was interested in what the grandparents were doing and how they were helping and that sort of thing [00:06:58,899]: And as I got older and became a grandparent I still was interested in the other stuff but I became more interested in why we do it because it’s hard work you know [00:07:09,380]: Come home at the end of the day sometimes after there’s been arguing and fighting [00:07:14,040]: But you know it really makes my life happier and more fulfilled [00:07:20,519]: And I think we sort of have an epidemic of unhappy grandparents at least in the U S and I think in other parts of the world too [00:07:30,959]: And you know sitting on the beach having your piña colada or golfing or whatever can be fine but you get a lot more satisfaction over the long run I think if you’re useful if you’re helping people [00:07:51,119]: Well I remember David Buss saying oh no sorry Steve Stewart Williams at the start of the April Winter Study Universe he’s talking about what is it that we are like maximizing machines or optimizing machines I can’t remember what it is that he says and he comes in to land that we are grandchildren maximizing machines or we’re grandchildren optimizing machines and that it’s not enough to just have a child it’s enough to have a child and make sure that your child has a child and then we’re kind of like ah okay my work here is done [00:08:22,859]: But yeah to kind of put it in context for the modern world one of the first things that everybody does is fly the nest [00:08:30,359]: You’re 18 you’re off to university you’re 22 you get your first full time job you move away to the big city and you don’t really think about your parents in that sort of a way you’re liberated you’re a renegade doing it on your own [00:08:42,619]: And then even in the modern world everybody has their own abode very few people are living in pan generational cities let alone pan generational houses or neighborhoods and then even with all of those incentives all of the opportunity to travel the world all of the different places and things that could distract you how many people when kids come onto the horizon and someone gets pregnant moves back to the city where one of the parents are [00:09:10,380]: Right [00:09:10,539]: It is so [00:09:12,119]: Maybe not anywhere near as common as it would have been ancestrally but to think you have all of this pull all of these dynamics distracting you to go out and there’s still something in the back of your mind that goes I think we should be near Nana and Grandad [00:09:25,400]: I kind of get the sense that we should be back there [00:09:28,960]: So maybe I don’t know maybe evolution is still whispering in people’s ears a little bit even in 2025 [00:09:34,419]: I think it is [00:09:36,380]: And then when they do it they’re very happy [00:09:42,539]: I mean it’s just sort of a truism [00:09:44,340]: If you talk to a grandmother or a grandfather and ask them you know what’s it like hanging out having the opportunity to hang out with your kids [00:09:54,340]: It’s the best thing ever [00:09:57,340]: And again the nice thing about being a grandparent is you’re not 24 7 either [00:10:03,539]: You can sort of do some of the other things like golf or hang out on the beach or whatever but you have more flexibility [00:10:13,840]: But yeah there’s this draw [00:10:17,219]: People just sort of naturally realize that that’s the way to go [00:10:23,940]: And that’s why I’m concerned about some of our younger generation that they’re good people a lot of like the young eco warriors and so on [00:10:36,679]: I read online them saying things like well the last thing the world needs is more children [00:10:45,719]: Well you make that decision early and then it’s hard to reverse that [00:10:51,359]: And I think it comes back to bite a lot of them [00:10:54,840]: But I also think kids are important [00:10:56,719]: I think kids are going to be the problem solvers [00:11:01,299]: We have a lot of problems that the world faces the planet faces and so on and it’s not going to be your dog [00:11:12,280]: I mean I love dogs don’t get me wrong but it’s not going to be the dog who’s going to figure out new ways to solve global warming problems or whatever [00:11:21,260]: It’s going to be our children [00:11:23,419]: And the problem with it is is you make that decision in your 30s and 40s and then you’re 50 and you might start to say oops and then it’s kind of late [00:11:36,900]: But one of the good things is that natural selection never had to be more specific than it needed to be to solve the problem [00:11:49,960]: So because we were embedded in these kinship networks and people like sex and when babies came they tended to be pretty willing to care for them and love them and want to nurture them that led naturally to reproductive success [00:12:08,739]: But not very few of us just walked around back in the Pleistocene saying I want to have children I want to have children because those other two things led to having children [00:12:20,539]: And so I don’t think early on as young people we think those things [00:12:26,880]: So it’s easy sort of to be led off track and say yeah I don’t want to have kids [00:12:35,000]: It’s not a good thing to have kids for various reasons and whatever and then suddenly think uh oh it’s too late [00:12:41,659]: Maybe I should have gone in the other direction [00:12:46,979]: So I worry about some of the younger generation doing that [00:12:51,820]: But what I was starting to get at though is because natural selection is not all that specific is you can probably make yourself happier and build a fulfilling life even after you’ve not had your own children and grandchildren just by helping [00:13:10,799]: Because we feel good about helping [00:13:13,260]: We feel good about being relevant [00:13:14,679]: So I would encourage people out there to even if they don’t have children to maybe do something that’s helpful for them and I think they’ll feel happier for it [00:13:27,840]: Maybe that’s the pediatrician coming out in me [00:13:31,739]: Okay so one big mismatch pan generational alloparenting and then the sort of inclusion of grandparents [00:13:45,419]: Is this in your opinion does this explain the grandmother hypothesis why it is that humans exist after they’re able to continue reproducing specifically mothers or grandmothers [00:13:57,299]: Yeah I do [00:13:58,619]: I think there’s reason to believe that menopause is pretty ancient that it started to happen right after the split from the other hominoid apes [00:14:13,380]: So basically selection stayed stronger for longer because we were doing things helpful increasing our reproductive viability later in life [00:14:24,400]: But selection for some reason didn’t push ovulatory function to later and later ages [00:14:32,479]: And I think the reason is is because it was more adaptive to stop at a certain age because children were becoming more helpless more altricial is the word and their period of dependency lasted a lot longer [00:14:52,159]: If you as a woman can have a child at 71 the potential chance just to kind of break that down for people who might not be familiar with the grandmother hypothesis can you give a basic bitch explanation of what it is like why that’s the case [00:15:08,599]: Yeah [00:15:09,559]: So women stopped reproducing directly in their 40s because as children were becoming more and more needy and the chances of them surviving and being successful if you died before they were 10 years old or so became very very very low [00:15:35,479]: And so it became adaptive to stop and nurture the last child that you had maybe when you were 40 years old [00:15:44,020]: And then so we would live that would keep natural selection stronger to later ages that need to reproduce indirectly by helping children you already had produced [00:15:59,559]: That held off the ravages of old age and so the whole thing just kept increasing so that eventually we lived long enough to take care of our children’s children [00:16:10,559]: And so the grandmother hypothesis sort of explains why we live to later and later ages but also why we don’t directly keep reproducing during that time [00:16:23,739]: I suppose as well limited resources food not only care but if you are able to contribute if you’re able to be a net positive to the survival of not only your children but your children’s children and maybe your friends children’s children and you get that reciprocally in return the alloparenting thing but you’re not that much of a drain on resources [00:16:52,940]: Older people don’t eat that much [00:16:56,179]: I guess they need care kind of eventually at some point but I would imagine that that care wouldn’t have been very protracted [00:17:03,099]: The end of life stuff I imagine isn’t that sophisticated ancestrally [00:17:08,859]: Right exactly [00:17:09,660]: Yeah I was listening to one of your podcasts with Peter Atiyah and he talks about slow death and long death [00:17:15,979]: And the slow death wasn’t there [00:17:18,939]: You were relatively fit and then something got you [00:17:21,920]: So you weren’t a burden on everybody back in the day like that [00:17:27,300]: And so even for males you brought up a good point [00:17:33,859]: They might not be taking care of the children rocking them to sleep and doing things like that quite as much as grandma did but just the male being around held together helped to hold together kinship networks and helped to transmit knowledge that had been accumulated like where the watering hole doesn’t go dry when we’re hunting for such and such and so on [00:18:00,260]: Males could be contributors also and if they weren’t busy getting beat up by younger males because they were competing for the females sort of dropping out of that game and being helpful in other ways probably was adaptive for them too and a route to indirect reproduction [00:18:22,020]: So grandparents pan generational raising alloparenting stuff like that mixed age play younger boys and girls learning from older boys and girls roughhousing understanding how status hierarchies work getting to expedite learning because the older kids know more and they get to teach the younger kids as opposed to everybody kind of moving and discovering at the same age [00:18:43,939]: What else [00:18:44,739]: How else is modern parenting out of sync with how we were evolved to raise children [00:18:48,979]: What are some of the least aligned child rearing strategies of the modern world in your opinion [00:18:56,300]: Well I think that covers it in terms of the sociology of it but we’re out of alignment in terms of infectious disease exposures and things like that with our daycare centers and so on stuff like that [00:19:17,540]: Kids experience different degrees of illness different types of germs different immune system developmental trajectories and so on [00:19:32,579]: And again I touched on this a few minutes ago but just [00:19:40,368]: I think it predisposes sometimes to some of the you know not super severe mental illnesses which I think come more from you know genetic and broken brain type what I call broken brain type phenomena but just some of the altered inputs from not carrying our children around all day long or having alloparents carry them around talking to them all day [00:20:09,688]: So those sort of early inputs are quite altered by the social structure that we now live in [00:20:18,708]: Should we see teenage angst or anxiety or ADHD as adaptations instead of diseases then [00:20:26,628]: Up to a point especially anxiety [00:20:30,128]: I mean you can’t live without anxiety [00:20:32,548]: If I could give kids a pill to make them never feel anxious then that probably wouldn’t be good for them [00:20:40,228]: I mean we you know if you’re walking down a path in the woods and you see mama grizzly bear with her cubs and you don’t feel a little bit anxious about taking the next step forward that’s probably not very adaptive [00:20:54,048]: So we need to feel anxiety but we need to learn how to deal with it because there are all kinds of anxiety producing situations that we have now that we didn’t used to have especially for teenagers [00:21:12,028]: You know they’re living in a virtual world a lot of the time and they’re you know they’re thrown into middle schools with you know 200 other kids their same age without support of a kin all day long and that sort of thing [00:21:32,908]: And that creates anxiety situations that we don’t need to eliminate per se [00:21:40,328]: We need to learn to deal with them [00:21:43,008]: How is modern child rearing and the environment that kids are brought up in potentially predisposing the anxiety the ADHD the teenage angst in a way that would have not occurred ancestrally [00:21:57,428]: What are some of the contributing elements to that [00:21:59,898]: Yeah well I think that it is you know having very supportive kin who love you all around that can sort of take you aside and say all right that’s not that awful of a situation and explain things to you [00:22:19,228]: But I’m always struck by and it’s not always a bad thing but I’m struck by the wide range of options that our teenagers face now [00:22:29,588]: When I was doing field work on EFOLOC which is not a hunter gatherer society it was a horticultural society but it was pretty primitive pretty isolated in a technological sense [00:22:41,648]: And those kids growing up knew what they were gonna do [00:22:45,228]: You were gonna fish you were gonna build canoes you were gonna you know weave mats to build roofs for the house and you were gonna take care of kids [00:22:55,428]: And you know that was about it [00:22:58,668]: There weren’t just this huge range of options [00:23:02,048]: And again I think it’s great that we have this huge range of options [00:23:06,448]: You know you and I wouldn’t be able to do what we do if we were living in that situation but it also presents so much uncertainty to these kids [00:23:16,448]: They sometimes just don’t know where to go and then they retreat into a virtual world and they don’t know who to you know they don’t have people around all day that they can talk to about it [00:23:28,688]: They don’t have older kids who have been through it necessarily to model after and so on [00:23:35,348]: So it’s pretty disruptive [00:23:38,068]: ADHD I think is a little different from anxiety [00:23:42,968]: I think what I tell kids and I may not be completely capturing the whole spectrum of it but I tell kids you know that I was five six back in the day and I’ve since shrunk [00:23:58,168]: And if the whole world were a basketball court I wouldn’t be very well adapted to it [00:24:02,708]: And now in school when we send kids to school we funnel them all through you know through the same funnel [00:24:10,408]: And so we kids who are you know a little bit shy quiet they’re not active learners they’re good at paying attention that kind of thing [00:24:21,328]: They get overvalued but the kid who’s a more active learner who would rather run around outside and learn things that way they’re not quite as able to [00:24:31,288]: But back in the day in the Pleistocene and in existing traditional societies there’s room for kids to do you know if you’re an active learner well you go out hunting [00:24:45,188]: If you’re a less active learner you make the arrowheads [00:24:48,748]: You know there’s all kinds of roles for kids that they could fill [00:24:54,908]: What are your thoughts on daycare [00:24:56,868]: On daycare [00:24:57,828]: Yeah [00:24:59,228]: Well I think well run daycares can be good in the sense that they can mimic the alloparental situation where you have multiple committed individuals and you know and especially if they’re like I think like in the Montessori settings they’ll have more of the like you know three year olds with four year olds with five year olds and so on [00:25:25,828]: I think those can have certain advantages but what I don’t like about daycares is that well first of all many of them are just overcrowded [00:25:35,408]: You’ve got you know the caretakers are overwhelmed and they can’t give the kids as much attention as they want but it’s the infection that’s there [00:25:46,868]: I mean we live up North here in Michigan where it’s cold six months out of the year and the viruses hit and you know parents you know they have their kids in daycare and in three days out of five they’ve got to keep them home because they have a fever or something and all of that [00:26:03,908]: So there’s a lot of infection risk that you have to deal with that you wouldn’t have had to deal with you know again during ancestral times [00:26:18,588]: So it seems to me like one of the big changes is a level of attentiveness from primary caregivers to babies and then children [00:26:28,928]: It seems to me like you’re suggesting it would be rare that children would be put down on the ground sort of left all that much [00:26:36,688]: Is that an accurate assessment [00:26:38,228]: Oh it’s absolutely true [00:26:42,428]: There was just no safe place to put a baby other than in a caretaker’s arms you know during the Pleistocene and before that [00:26:52,128]: Have you got any idea just thinking on that is there any data around the difference in skin to skin contact time from ancestral times to the modern world [00:27:03,208]: I think we know we’re probably gonna be talking what 10 maybe 20 [00:27:07,528]: Yeah I don’t know of any data [00:27:09,768]: It’d be an excellent study for somebody to do [00:27:12,528]: And maybe somebody has [00:27:13,948]: If they have I don’t know [00:27:15,848]: But I think it’s way down [00:27:18,828]: And things like you know plagiocephaly the flattening of the head [00:27:24,168]: When kids are held you’re always switching arm to arm different positions [00:27:30,468]: And same thing with co sleeping you know doing it safely [00:27:36,968]: Kids parents would you know mom would sort of curl around baby [00:27:41,868]: They’d be in different positions and so on [00:27:44,108]: We can just see now that like six I think one out of six kids in the U S gets these head flattening conditions called plagiocephaly and it’s from not being carried [00:27:55,968]: It’s from being flat on your back [00:27:57,808]: Oh wow it’s literally an imprint of the floor that you were laid on for so long when your cranium was still malleable [00:28:04,808]: Exactly [00:28:05,628]: And then the related condition is torticollis where you get this neck tilt [00:28:10,468]: And then you gotta send them for physical therapy to try to straighten it out [00:28:15,468]: So those are you know easily seen things things you can notice [00:28:21,048]: But I also wonder if you know we have all these sensory issues that come up in kids now sensory integration disorders and so on that tend to you know they can if they’re extreme they can put them on the autism spectrum and so on [00:28:36,128]: And I’m just wondering if you know you get different sounds sights smells orientations and so on that when you’re being carried around and talked to constantly as opposed to stuck in a corner and some kind of little device or carrier if that doesn’t impact the development of you know our sensory machinery up there in the brain [00:29:03,908]: Well think about all of the talk of attachment styles and attachment disorders anxious attachment avoidant dismissive [00:29:13,209]: I don’t know [00:29:14,088]: I mean even the studies where baby is left in room toys are strewn around mom leaves room mom comes back in baby calms back down [00:29:22,068]: Eventually how far does baby go away from mom [00:29:26,628]: I’d be fascinated to see the ancestral equivalent of that [00:29:30,908]: You know how amazing it would be for us to be able to run some of these split tests experiments [00:29:39,348]: So you mentioned that co sleeping where would babies have slept ancestrally [00:29:44,848]: How would they have slept [00:29:45,868]: What’s the typical sleeping environment [00:29:47,948]: Like give us a breakdown there [00:29:49,149]: Well co sleeping was the rule [00:29:50,368]: I mean they didn’t have soft beds and things like that and heavy comforters [00:29:57,588]: Mostly would have been done on mats or on firmer surfaces and it would be generally mom would curl around the baby [00:30:06,968]: The term that’s thrown out there now is it’s called breast sleeping [00:30:11,608]: There’ve been videotapings of how moms just sort of instinctively curl around baby and then you know pat her on the head while they’re not even awake and baby has the breasts available and can go from side to side [00:30:25,928]: So in my view you know I mean that’s the way we always slept [00:30:30,368]: There were no separate rooms or beds or anything like that [00:30:33,528]: So it’s not co sleeping that’s dangerous [00:30:37,248]: It’s co sleeping dangerously that’s dangerous [00:30:40,468]: You know if you’re trying to do it on a couch or something where baby’s head can get wedged in the pillows and that you know or the cushion you know that can be dangerous [00:30:50,908]: But I think Japan is a good case in point [00:30:57,209]: Co sleeping is generally the rule there [00:30:59,608]: And they have half the SIDS deaths and half the mortality rate that we do [00:31:05,868]: So it’s not co sleeping per se [00:31:07,968]: I think it’s co sleeping unsafely that is the problem [00:31:12,008]: And I think co sleeping has some advantages in terms of development [00:31:17,269]: And it’s you know this gets me in trouble or at odds with the American Academy of Pediatrics [00:31:24,388]: And I understand I mean they’re speaking to a national population and they have to be talking to people who you know maybe they live in an impoverished situation where they don’t have safe bedding or maybe dad’s an alcoholic [00:31:40,988]: And if he hops in bed that does put baby at risk and you know all these things [00:31:45,168]: So I sort of understand their position but just coming out as they do hard stance against any co sleeping I disagree with [00:31:53,908]: And a lot of the European countries are coming around to that view too that it’s okay to do it as long as you’re being careful [00:32:01,508]: Talk to me about the transport response in infants [00:32:05,068]: The what [00:32:05,688]: Transport response [00:32:07,488]: I don’t know what that is [00:32:09,428]: When babies they seem like they fall asleep more easily when they’re being walked whilst carried [00:32:15,149]: Is that not [00:32:15,508]: Yeah [00:32:15,908]: That was Rob Henderson and me were talking about it earlier on that if you want to put a baby to sleep you put them in one of those I guess rocking you know it’s like an automaton thing [00:32:27,548]: And you’re thinking okay so what are you trying to simulate there [00:32:30,329]: You’re trying to simulate being carried right [00:32:33,568]: Carried exactly yeah yeah [00:32:35,368]: I know I just spent a week off with the grandchildren one of them six months and I just kept saying to myself why won’t you let me sit down [00:32:46,068]: Walking around [00:32:47,248]: But they just don’t [00:32:49,188]: They want you up you know [00:32:50,968]: And yes they What’s the adaptive explanation for that [00:32:54,269]: Why would that be the case [00:32:55,368]: Is that safer [00:32:56,108]: If baby’s being carried and moved it’s less likely to be eaten [00:32:59,748]: I think probably it has something to do with that [00:33:02,329]: I mean certainly being carried and being in close proximity I think babies feel anxious when naturally just feel anxious when they don’t have that proximity [00:33:13,628]: I’m not quite as sure about you know why they want us to be expending the maximum amount of calories carrying them about and rocking and bouncing [00:33:24,468]: But you know what you just hypothesized there or speculated is that they that’s sending them signals that they’re being held that they’re being cared for you know that it could be something as straightforward as that [00:33:38,149]: They’re a meal on wheels as opposed to a TV dinner [00:33:41,488]: And it’s harder to catch the meal on wheels especially if the wheels are mom or dad [00:33:46,769]: Yeah okay [00:33:47,329]: So why what about some explanations for why toddlers might wake up at night or throw food or act out [00:33:54,228]: Why might those be smart behaviors in some way [00:33:59,188]: Yeah well toddlers wake up at night because they wanna check in with you know mom and dad I think [00:34:08,588]: And you know they don’t have as much incentive to you know they don’t have to get up and do anything in the morning [00:34:15,769]: And so they’re free to satisfy their whims that way [00:34:23,288]: As far as throwing food and tantrums if they don’t get their way well there are a couple of things [00:34:31,748]: Throwing food especially vegetables and new foods [00:34:35,608]: I think that toddlers once you’re mobile you have this natural aversion to just putting anything in your mouth [00:34:47,568]: Unlike when you’re you know four months old you’ll put anything in your mouth [00:34:51,269]: But as you get more mobile if you’re you know just crawling about or toddling about the campsite if you’re willing to put everything in your mouth that’s probably not gonna be good for you [00:35:02,008]: So you hand a six month old a stalk of broccoli they’ll eat it [00:35:07,728]: You hand a two year old a stalk of broccoli they’re likely to throw it to the floor [00:35:12,468]: And I think that makes some good adaptive sense [00:35:18,028]: As far as tantrums go and just being very very needy I think I don’t really know what the adaptive explanation is for that but I do you know think that they just cognitively they’re not very empathetic yet [00:35:39,068]: They can’t really put themselves in another individual’s position and say well mom is busy right now [00:35:46,988]: She can’t carry me around even though I wanna be carried around [00:35:50,508]: And you know and so they just want what they want [00:35:54,788]: And you know at one moment they might wanna give you a kiss and the next moment they wanna hit you over the head or something just because they I don’t think they’ve got it all figured out yet [00:36:06,888]: You know they’re still learning how to be social [00:36:09,788]: I mean they’re much better at it than say a chimpanzee would be at a similar age but it’s a long learning process in humans learning [00:36:20,348]: I mean we’re the hyper social species right [00:36:23,228]: That’s how we’ve prevailed is we know how to get along in groups and we reciprocate with one another [00:36:31,888]: And it’s a long lesson for kids to learn sharing [00:36:35,968]: You know it’s not an easy concept but it takes a long time to learn it [00:36:43,368]: And that’s why a lot of alloparents a lot of help and taking a long time to do it is very important [00:36:51,708]: That’s why those things have evolved I think [00:36:53,688]: As an only child you are speaking my language here struggling to learn to share et cetera [00:37:01,068]: What do we know about breastfeeding [00:37:04,409]: We know it’s the best way to go and it has numerous advantages for baby and mother [00:37:14,988]: You know it helps establish a proper microbiome [00:37:18,429]: It helps protect you early on in life when your own immune system is still getting up and running [00:37:25,828]: Protects you especially from diarrhea illnesses which used to kill a lot of babies back in traditional societies [00:37:36,568]: There’s some evidence I don’t know how solid it is but there’s some papers that I’ve read suggesting you get four to five extra IQ points if you’re breastfed for a long period of time versus just imbibing in formula [00:37:52,448]: There’s some evidence that the microbiome interaction with the immune system and the nervous system can help reduce risks of developing mental angst problems depression and so on later in life [00:38:10,649]: And then of course for mom moms reduce their risk of breast cancer from breastfeeding [00:38:17,669]: No way [00:38:19,169]: Yeah yeah [00:38:20,289]: Wow [00:38:21,429]: And there’s a really cool study [00:38:24,088]: It seems to be pretty empirically sound [00:38:27,208]: It was very surprising to me [00:38:28,608]: It’s in evolutionary medicine and public health from a couple of years ago showing that moms who breastfeed their babies have a lower incidence of developing early dementia [00:38:42,468]: Oh my God [00:38:43,688]: How much is that selection [00:38:44,929]: They’re making some correlate there [00:38:46,149]: I was gonna say it could be a selection effect [00:38:48,188]: Yeah right yeah [00:38:49,588]: So I don’t know [00:38:51,409]: But yeah multiple multiple benefits from it [00:38:53,688]: And unfortunately you know we don’t grow up with it [00:39:02,010]: I have some very smart parents in my practice and they’re surprised when I tell them babies are designed to breastfeed for a couple of years and they don’t know about breastfeeding and they come in from the hospital even if they’ve talked to a lactation consultant with their spreadsheets and so on baby’s done this baby’s had so many poops and so many voids and blah blah blah and they’re all uptight and milk’s not coming in yet and somebody’s telling them they have to supplement and it all just interferes with breastfeeding [00:39:36,330]: You have to relax [00:39:37,290]: It just happens [00:39:39,850]: There’s no breastfeeding failure in traditional societies or it’s very very rare [00:39:46,250]: Everybody sees it happen [00:39:47,570]: They know how to do it but we have I think it’s less than 50 of U S babies are still breastfeeding at six months and a lot of them don’t even get that far into it because they worry about the initial weight loss or they worry about the jaundice that develops when you’re getting a little bit dehydrated and breast milk’s not there yet and it’s not washing out bilirubin and so on and they start introducing formula and then baby says oh well this is easier and learns to prefer the bottle over the breast [00:40:30,630]: And so more often than you might think both baby and mom end up giving up on what’s best for them [00:40:40,310]: But both parties have been weaned off of breastfeeding [00:40:43,850]: Yeah right so yeah [00:40:45,750]: That’s interesting [00:40:46,710]: What about C sections [00:40:49,810]: Yeah I mean I think C sections obviously can be life saving and are necessary in some circumstances but I just think that in some birthing centers they’re just a little bit too cavalier about it [00:41:07,430]: You know mom’s got something coming up or the doctor’s got a vacation you know and it’s just ah you know you’re at 40 weeks now let’s not let it go too long let’s just do a C section that kind of thing or let’s induce same sort of thing [00:41:23,370]: So mom and baby have evolved a really good communication system for when baby is supposed to come and we’re not always really good at estimating what the exact conception date is [00:41:36,550]: We know that because you know some babies are conceived now through artificial insemination and we know then when they are conceived and we know that we’re a little bit off when we’re estimating using ultrasounds and when mom thinks her last period was and so on [00:41:54,270]: So I think they’re overdone basically is the short answer [00:41:59,850]: They’re life saving wonderful interventions if done appropriately and much more sparingly than they are done now [00:42:09,950]: Same with inductions [00:42:12,470]: I just don’t love to hear ah you’re 41 weeks and everything looks good but maybe we should just induce you right now [00:42:22,370]: Well if everything looks good I always want to wait a few more days you know so [00:42:29,870]: Have you got a perspective on epidurals [00:42:34,730]: Is there any insight there [00:42:37,570]: I’m not a real expert in that but what I’ve been told by moms and people that have them is it can interfere a little bit with pushing and getting the baby out and so then that can increase your risk of some doctor saying ah we better do a C section here that kind of thing [00:42:58,870]: Is there such a thing as a pot epidural [00:43:01,290]: Can you reduce down sensitivity by 50 or something like that do you know if they can tolerate it [00:43:07,010]: You know that’s a good question [00:43:08,530]: I don’t know the answer to that [00:43:10,430]: You would think that would be a good idea [00:43:12,850]: I mean it’s easy for me to say you know don’t do epidurals [00:43:18,670]: But I mean my daughter and daughter in law were able to do it and yeah I guess they’re pretty tough but probably no tougher than the average so [00:43:29,050]: Do C sections interrupt lactation [00:43:32,070]: I think so because again there’s this fine tuned timing mechanism between when baby should come and when nursing should start but also mom’s sore [00:43:44,270]: I mean it’s a surgery and mom doesn’t feel quite as good and it’s just harder for mom to get things going and be quite as committed and diligent to it when you’re recovering from a surgery [00:43:58,910]: I mean I could see you know that if I had to do some type of childcare thing obviously not breastfeeding but I had just had a hernia surgery or something I might be less reluctant to carry out my duties in that situation [00:44:16,130]: So I think it probably does interfere some [00:44:19,030]: I imagine that you have some concerns about surrogacy in that case then [00:44:23,890]: Yeah yeah that I haven’t experienced too many people who’ve done it and I haven’t run into any problems but yeah there certainly can be you know it’s a sort of a mismatched kind of thing [00:44:40,530]: It’s a not very novel sort of thing so we would expect there could be some problems there that crop up [00:44:48,870]: Childbirth child rearing in the modern world certainly seems to have become very medicalized [00:44:55,210]: I wonder whether this over medicalization could contribute to fertility decline in some way [00:45:04,170]: Yeah I think so [00:45:07,080]: Like I said people come in with their spreadsheets and I have to tell them forget about counting the number of dirty diapers and all of those things and people you know they come in with yeah they’ve had C sections it’s been over medicalized and it’s just a much more stressful kind of thing than it is most likely in a more natural setting [00:45:39,220]: I think midwives often get people to relax [00:45:42,300]: There’s also a home birth trend which you know I mean I see the reasons for it and when it works it works but it’s also more risky you know if something because things do go wrong and modern medicine you know like again like your previous podcast with Peter Atiyah we’re good at fast deaths we’re good at avoiding those [00:46:12,480]: If something goes wrong you want to be there you want an obstetrician there who has a scalpel on hand if you need it yeah so anyway yeah [00:46:23,180]: What have you come to believe about the current demographic transition these declining birth rates that we’re seeing [00:46:30,080]: Yeah well that’s sort of what my early interest was as a graduate student [00:46:34,600]: When I went off I went to Penn State and worked with an anthropologist named Napoleon Chagnon and he was very much into evolution [00:46:48,460]: He was a cultural anthropologist who was becoming an evolutionary anthropologist and I followed him in Northwestern my second year and I had to figure out something to do so I would go into the library and I got interested in demographic transition and there was not a really good explanation in my mind for why people in modern settings had decided all of a sudden you know they’d switch from we want to have as many babies as we can to we want to have just a couple or in some cases none and the prevailing ideas out there the prevailing theory was coming from economists and economic minded demographers and their thought was well in traditional settings after you pay this little upfront cost kids become assets [00:47:37,600]: They make you wealthy basically and especially they take care of you and things like that so there’s no reason to limit reproduction in traditional settings but because they lived in modern settings and they probably had kids they knew kids were expensive in modern settings and so they were arguing that we would limit the consumption of children expensive goods just like we would limit the consumption of all other expensive goods but that didn’t make sense to me from an evolutionary point of view [00:48:09,960]: First I didn’t trust their data because they would go into these traditional societies and ask hunter gatherers why do you want to have so many children [00:48:18,420]: And that would be like asking you know why do you breathe [00:48:22,920]: And so I think I thought they probably teased out the answer they wanted but you know I have no way of knowing that so but what really troubled me was it didn’t make sense from an evolutionary point of view that we had kids in order to eventually economically exploit them [00:48:41,020]: Again going back to this idea that we had lifespans maximum lifespans as long as the other apes and then they gradually increased and doubled because we were doing things useful for our children that sort of idea didn’t jibe with the idea that you know once they became 20 or 30 and we were 50 or 60 that you know we were just going to kick back and let them take care of us [00:49:11,860]: I always felt it was going to be the other way around and that’s what my early work contributed to the grandmother hypothesis and as it contributed to what we now consider to be the right explanation for why lifespans doubled [00:49:26,740]: But this notion that wealth flows switched as modernization occurred and that’s what made us not want children didn’t make full sense to me [00:49:42,060]: Now it does make sense that children of course became more expensive as we left traditional settings and stuff but they were always expensive [00:49:54,560]: They never really gave us more than we gave them except in terms of life satisfaction maybe but so my explanation is just that that we don’t have kinship networks anymore that help spread out the costs of rearing children [00:50:12,900]: Costs get concentrated on mom and dad [00:50:15,600]: Mom and dad say you know this is hard work [00:50:18,380]: We love these kids but we’re only going to have one or we’re only going to have two and some people look around and say oh my friends over there are struggling [00:50:25,620]: I’m not having any [00:50:27,460]: So I think it has a lot to do with the demise of extended kinship networks and that help in the concentration of care responsibilities on the decision makers [00:50:42,600]: I’ve spent a lot of time thinking about this much to the internet’s distaste but one thing that I don’t think it’s talked about sufficiently is the sort of mimetic desire to have children to that oh wow my next door neighbor they just had kids and or my sister just had her first boy and she seems really happy [00:51:05,860]: And that’s a good maybe I should think about that you know fewer children beget fewer children beget fewer people seeing children et cetera et cetera [00:51:13,440]: And yeah it’s the vicious other side of the blade of being a hypersocial species as you said or ultra social species [00:51:23,120]: So moving on to we’ve talked a lot about sort of development child rearing the more sort of psychological and social side of stuff [00:51:30,500]: If we get into the more medical elements of the pediatrics what are some examples of medical missteps that could have been avoided if we’d had some evolutionary thinking [00:51:43,440]: Well the big one that I worked on has to do with food allergies childhood food allergies [00:51:53,120]: Back in the 90s and it was officially codified by the American Pediatric Society in 2000 or 2001 I think it was that you delay delay delay when it comes to the introduction of the eight or nine most allergenic foods [00:52:14,940]: And I mean first of all that evolution aside that just never made sense from an immunological point of view [00:52:21,380]: It just I don’t know how they came up with that idea because once the immune system is able to cause destruction which starts in utero and is present in a big way even shortly after birth you have to have proper tolerance mechanisms [00:52:37,680]: It’s not like you can wait till you’re three years old to learn not to attack your own liver [00:52:44,240]: So why they thought waiting till you’re three years old to introduce peanuts you know is really really beyond me [00:52:53,060]: But the evolutionary angle there that if they had been more attuned to how we lived you know during the Pleistocene and before that we were immobile pretty much as a species [00:53:07,260]: We didn’t you know we grew up in and died in the same ecosystem basically generation after generation [00:53:18,880]: So what that meant was that while mom was while you were inside mom and she was eating you were getting exposed to food antigens [00:53:27,060]: When you were she was breastfeeding you you were getting exposed to food antigens [00:53:30,600]: When you first started eating foods yourself you were getting exposed to food antigens [00:53:35,800]: And those food antigens were the very same ones that you were going to get exposed to for the rest of your life [00:53:43,080]: And so they eventually learned not through thinking about it theoretically in any way but just by going oh my goodness food allergies are soaring [00:53:55,880]: And oh look they’re not allergic to peanuts in Israel because they feed children early on [00:54:02,420]: They call them bamas which are peanut butter containing biscuits [00:54:09,400]: And so people started looking well maybe we made a mistake here [00:54:13,360]: Maybe we should introduce things early [00:54:15,180]: And so they eventually did some studies and found out that that was true [00:54:20,820]: But if you thought about the way people always ate you would be introduced to all the foods you would ever eat all the allergens all the antigens that you would ever encounter early on in your immune system would learn to tolerate them [00:54:36,080]: And so it never made sense to say let’s not introduce things until you’re older [00:54:44,640]: So I think evolution mindedness could have helped us to avoid that problem [00:54:54,140]: You know but I mean I think there are others [00:54:59,720]: I think evolution mindedness can help us to understand what’s a healthy diet [00:55:08,040]: It can contribute to that [00:55:09,740]: I mean I know from listening to you you’re interested in that [00:55:16,790]: Well it turns out there’s a really cool study that was done with fruit flies by Michael Rose and his group [00:55:27,140]: Grant Rutledge is a grad student or a fellow who worked with him [00:55:32,560]: And what they did was they changed up the diet that the fruit flies had evolved to eat [00:55:41,300]: They had been eating for thousands of generations [00:55:44,900]: They had been eating apple rot [00:55:46,860]: And then they brought them from that area which I think was on the East Coast to Michael Rose’s lab in UC Irvine [00:55:55,620]: And they didn’t have rotten apples I guess [00:55:57,960]: So they fed them bananas doused in high fructose corn syrup [00:56:02,440]: And what they found was that after about 40 generations flies had adapted to that new diet to accommodate it really well while they were young [00:56:14,420]: But even after 100 generations they hadn’t adapted to accommodate that new diet when they were old [00:56:21,900]: And the most parsimonious explanation for that is that number one selection is most powerful early in life [00:56:29,620]: And number two most genes have their effects confined to certain ages [00:56:35,720]: So that if a mutation comes along that allows a young fly to better digest a banana or if a mutation comes along that allows an old fly to better digest the banana potent selection would accumulate for the young fly [00:56:56,280]: Weak selection would not accumulate for the old fly [00:56:58,840]: Is this why kids tolerate modern diets better than grandparents do [00:57:02,760]: Exactly [00:57:03,660]: Exactly [00:57:04,340]: That’s right [00:57:04,940]: So beyond a certain age maybe 50 or so maybe earlier you should lay off the pancakes and donuts and things like that [00:57:17,680]: I mean nobody should be eating too much of that stuff [00:57:20,540]: But you can certainly kids can do it [00:57:22,360]: They can tolerate it much [00:57:23,960]: They can tolerate a grain heavy diet much better than say somebody my age [00:57:29,160]: That’s so interesting [00:57:30,380]: It’s because of that [00:57:31,460]: Yeah [00:57:32,020]: Yeah you can apply that also that line of reasoning to infectious disease [00:57:38,320]: And I did that in an article shortly after the pandemic got going [00:57:44,960]: Crowd diseases came on board once we started settling down and living in crowds moving indoors and so on [00:57:53,260]: Things like influenza and tuberculosis and all those sorts of illnesses [00:57:59,660]: And so as long as those diseases had certain commonalities like they relied on crowding and maybe breathing in aerosolized virus that kind of thing [00:58:13,146]: young immune systems should evolve more quickly to be able to adapt to those crowd diseases than old immune systems would [00:58:26,126]: And there’s an evolutionary biologist that I’ve talked to who works with fruit flies who’s interested in maybe trying to test that idea [00:58:35,466]: But it’s a little more complicated with immunology or with infection than it is with diet because we have a very potent adaptation immunologically that helps us when we get a little bit older to fight diseases and that’s immune system memory [00:58:57,746]: So very very young children often don’t do as well with infection [00:59:02,686]: Oh of course because They haven’t acquired memory yet [00:59:05,706]: You’ve accumulated all of the different blueprints of all of the different pathogens [00:59:10,746]: But when you’re talking about a brand new virus that’s just jumped into the population No one has any protection [00:59:18,866]: Memory doesn’t count anymore [00:59:20,566]: And then you should expect the young to have again they have to be commonalities [00:59:26,866]: And there are four other coronaviruses out there that passed through over the last 10 000 years [00:59:33,546]: You would expect young people to have evolved adaptations to deal with those infections to a better extent than old people just as you would expect it for diet [00:59:47,646]: What about obesity in kids [00:59:52,206]: Are there some evolutionary insights that you’ve come to believe with regards to that [00:59:58,446]: Yeah I mean obviously it’s just a terrible problem in our society [01:00:06,686]: Yeah and like you said it can start early [01:00:10,866]: And I mean I think largely comes from a mismatch [01:00:14,626]: We used to have to work harder for our foods and exert ourselves [01:00:22,606]: And calorie dense foods were not as available [01:00:25,826]: So we developed a taste for those [01:00:28,386]: And now that we don’t have to work hard to get the calories and we still have the taste for them many people overdo it [01:00:37,226]: And they get their kids on that wagon quickly too where they’re over consuming [01:00:44,506]: And then there’s also just foods that nobody’s had time to adapt to [01:00:49,466]: There’s stuff in the center aisle of the grocery store you know the trans fat laden things and all that that people soda pops and those kinds of things that people bring into their house [01:01:04,906]: And so it’s a daunting problem though [01:01:08,266]: You can explain it to people [01:01:10,146]: It’s easy to get [01:01:11,406]: It’s easy to understand that mismatch [01:01:15,006]: But getting people to you know be more active and avoid some of those foods is just a hard thing [01:01:27,426]: I dread it when I’ve got a 10 year old who can’t hop up onto the exam table [01:01:34,486]: He already weighs 130 pounds and you know his parent sits down on the bench in the room and you know they weigh 300 pounds [01:01:44,126]: I mean what can I do [01:01:45,726]: You know if I could take the kid home with me you know maybe I’d have a chance but it’s a really really hard problem to solve [01:01:56,726]: But I think it’s just such an important thing [01:02:02,146]: I mean especially I mean it’s a problem in kids but it’s especially a problem in you know as people get older [01:02:11,786]: And you know I don’t know what the number is but so many of our healthcare dollars get spent keeping people who’ve abused themselves you know for five six decades alive or you know trying to keep them partially alive at least [01:02:30,366]: And I mean I think most of our healthcare dollars get spent trying to keep somebody alive for the last three months of their lives and that kind of thing [01:02:38,186]: Is that right [01:02:39,106]: I think so [01:02:43,226]: And it’s not that I’m against helping people when they’re older but if people would help themselves when they were younger and avoid some of these problems all those healthcare dollars could be shifted to young people and you know daycares could be better [01:03:00,666]: And then the mom stuck at home with three kids and no help [01:03:04,606]: I mean we could reallocate a lot of these things as a society if people were just more responsible [01:03:12,366]: But it’s a tough problem isn’t it [01:03:13,866]: I mean you know [01:03:14,366]: Yeah it’s not just responsibility right [01:03:16,046]: It’s hypernormal stimuli calorie dense foods [01:03:18,686]: We’re not adapting for the salty sweetie [01:03:21,526]: Absolutely [01:03:21,926]: Fluffy crunchy you know all of the design [01:03:27,046]: Yeah we’re up against all of that in trying to get people to change [01:03:31,446]: When it comes to medication do you think are we maybe overusing medication in some ways for issues that might be biologically meaningful [01:03:39,166]: Are we stepping into important processes that wouldn’t have obviously been intervened with ancestrally [01:03:45,386]: I mean I think so [01:03:47,306]: I think antibiotics are wonderful inventions in life saving but they’re certainly overused [01:03:54,446]: And so that leads to the evolution of resistance and stuff [01:03:58,066]: But the big category that I think is overused are the psychotropic medications the putting teenagers on multiple antidepressants and ADHD medicines and so on [01:04:16,586]: I’m always happier to start with changing behaviors modifying behaviors start with some counseling start with some explanation explaining to kids that it’s natural and okay to feel anxious [01:04:33,806]: Have you heard about the smoke detector principle [01:04:36,966]: Of course yeah that it’s better to think there’s a fire and then not be one than it is for there to be a fire and you not go off [01:04:43,306]: Right right [01:04:44,146]: So anxiety sort of operates that way [01:04:46,946]: We get anxious and there’s just so many things out there now to get anxious over [01:04:50,506]: We have to learn to deal with it rather than take a pill to try to eliminate it [01:04:54,666]: So I think there’s a lot of overuse [01:04:57,266]: And of course the SSRIs that are used so commonly don’t probably work as well as sustained exercise does over the long run [01:05:08,886]: And you know but it’s a lot easier to take a pill you know and people often choose the easier way and there’s a lot of pressure you know from the television and other media telling you take this antidepressant and if that doesn’t work maybe another one will make you happier [01:05:28,866]: So I think yeah I think it’s overused [01:05:31,126]: And I think having an evolutionary perspective can which includes something like the smoke detector principle can help us to sort of pull back on some of those things [01:05:44,466]: And of course these old people we talked about who are unhappy because they aren’t taking care of their grandkids and their SSRIs well move closer to your grandkids [01:05:55,346]: I think that’ll work better [01:05:57,506]: I would love someone to do a study you know pay for older people to move closer to their grandkids and give the other group SSRIs and see which one’s happier [01:06:09,006]: Yeah it’s really interesting I think considering how modern interventions that are well meaning and help and are needed in many contexts I think a lot of the time it’s the over prescription in the same way as it’s not bad that we have cheesecake [01:06:29,306]: I’m really really grateful for the inventor of cheesecake and for the Earl of Sandwich and his invention of the sandwich [01:06:37,006]: But it’s the over application of these technologies and these foods that cause the issue [01:06:44,606]: What would I’m interested what would an NICU look like if it respected evolutionary design do you think [01:06:54,646]: Well you would allow parents mothers to be in contact with their babies more [01:07:02,806]: And they’re doing that to some extent [01:07:05,346]: You would be you know you would be introducing breast milk as early as you can [01:07:13,366]: You would be I mean I saw I don’t know how common it is but when I was a resident in the NICU you know I saw babies who were induced or made to come early who then had breathing difficulties and ended up in the ICU and on ECMO of all things because of you know kind of stupid errors like that [01:07:41,746]: And so I think just trying to being less cavalier about inductions and C sections would help change the complexion of NICUs but just allowing more parental contact [01:07:59,266]: You know they have and I think there’s movement towards that [01:08:04,286]: There’s good information that they’re trying to the problem is it comes slower than I would expect because they have to wait for a study to show it over and over again before they you know before they’ll intervene in a way that’s and that makes sense if it’s dangerous intervention but if it’s an intervention like let mom hold her baby more it doesn’t seem like it’s that dangerous to me [01:08:32,726]: We might not have to and it might make sense from an evolutionary perspective [01:08:36,506]: We might not have to wait for six multicenter studies to be done in order to conclude that that’s a good idea [01:08:43,506]: So again when it’s a dangerous intervention potentially dangerous intervention you want to have all those multicenter studies done but doctors in my opinion you know for good reasons are a little bit leery of theory [01:09:02,306]: Nobody wants their doctor that’s dreaming up a treatment for them in the shower the morning before that’s just you know kind of a wild speculation [01:09:14,186]: Evidence is a good thing but it can be overdone too [01:09:19,266]: Doctors just you know medical students they’re just not taught theory the same way graduate students are in other scientific disciplines [01:09:30,786]: And of course I’m partial to evolutionary theory and I really wish that you know it made its way into the licensing exams and it made it into the pre med programs and all that [01:09:44,026]: I was thinking about when I got into medical school I had already had a PhD and I was teaching at University of Michigan and they let me in which was great but they said I had to go take an organic chemistry course [01:09:58,046]: So I went to the local community college and took that and I’ve never really had to know any organic chemistry in anything I’ve ever done as a pediatrician [01:10:10,426]: But if rather than that or at least in addition to that I’d love to see pre med programs include evolutionary biology courses and I’d love to see continuing medical education include more evolutionary biology [01:10:27,806]: And I’d really love to see more evolutionary biology undergraduates decide to go to medical school [01:10:33,466]: That would be a real boon to the discipline [01:10:38,646]: I’m all for it [01:10:39,806]: I’m super all for it [01:10:41,246]: I think all parents need to read in fact all single people need to read a behavioral genetics book as well if you’re intending on having kids at some point [01:10:52,686]: I think all of the dating advice in the world and all of the child rearing books in the world could be replaced with Blueprint by Robert Plowman maybe [01:11:03,026]: Look if you wanna have a family at some point it is made up of the raw materials of the person that you make them with and it’s the single most important decision in a child’s happiness [01:11:11,426]: You can’t out educate bad genetics bad you know what I mean like a difficult genetic suboptimal in your choice [01:11:20,386]: So you mentioned evolutionary theory [01:11:23,286]: You’re a fan I’m a fan [01:11:25,826]: What are the risks and are there risks in misapplying evolutionary theory to social or medical contexts [01:11:36,886]: Yeah if it’s badly applied [01:11:39,246]: I mean there’s this whole it’s been a ways back now of social Darwinism and so on so people can misunderstand and think that it’s all about calling the weak and sick from the population and doing things [01:12:00,306]: I did an interview years ago for one of the science magazines where the interviewer a real nice woman wanted me to make clear that as a Darwinian pediatrician I was in favor of taking care of the weak and the sick also because she thought Darwinism implied that some people might think that that’s not the case [01:12:20,866]: So I mean I think done poorly social Darwinism can creep in [01:12:29,106]: Evolutionary biologists if you hang around in those circles you’ll often hear them say evolution is or the theory is descriptive not prescriptive [01:12:37,966]: And it is it’s up to you but in a little sense in evolutionary medicine we kind of violate that in the sense that we’ll say things like you know we might prescribe letting that fever go because fever is an evolved adaptation that helps you to fight your illness [01:13:01,006]: So we’re being I mean we’re not forcing anybody’s hand but we’re giving advice that says avoid the trans fats let the fever go let the you know those kinds of things [01:13:11,546]: So we’re being a little bit prescriptive I guess [01:13:13,966]: I have a friend who is very forward thinking around his health early thirties guy and he actively seeks out illnesses that cause fever [01:13:28,826]: And this is because of some evidence that he’s looked at that suggests that getting a fever and raising your body temperature internally is good it’s protective against cancer growth because it burns that through [01:13:43,146]: Whereas you know immediately you have a fever and what are you doing [01:13:48,126]: I’ll regulate with air conditioning I’ll take something to bring down the temperature I’ll go in and see the doctor so on and so forth [01:13:56,866]: Yeah it’s funny the problems that are caused by being able to fix problems you know [01:14:05,546]: Right right no you’re right yep [01:14:09,406]: And without recognizing that some of them are defenses [01:14:13,586]: If it’s normatively bad feeling sick with a fever is normatively bad and so doctors exist to fix things and make you feel better [01:14:22,506]: And so we tell you to take you know the old saying not in pediatrics but the old saying for adults is take two aspirin and call me in the morning right [01:14:32,626]: And we don’t give aspirin to kids but the idea is the same [01:14:39,006]: We often tell them take your ibuprofen or your acetaminophen you’ll feel better [01:14:45,226]: And there are rules for those things [01:14:47,146]: It’s not like you can never use them but it’s yeah like you said fixing things often makes things worse [01:14:56,726]: Paul Turk ladies and gentlemen Paul you’re awesome [01:14:59,326]: I think an evolutionary perspective on child rearing was desperately needed and I’m really glad that Rob introduced me to your work [01:15:07,386]: I think it’s so great [01:15:08,446]: Where should people go [01:15:09,106]: They’re gonna wanna keep up to date with the stuff that you do and get ahold of the book [01:15:14,426]: Yeah I mean the book’s available on Amazon [01:15:18,186]: It’s called Bringing Up Baby An Evolutionary View of Pediatrics [01:15:21,886]: They can go to my website [01:15:24,866]: Anybody who wants to ask me a question about their child they can call my office [01:15:34,986]: How amazing [01:15:37,576]: I’m always interested to talk to people about evolution and child rearing [01:15:44,646]: I’ve had I’m fortunate to have so many wonderful parents in my practice who sometimes I feel like I might be boring them with some of this right [01:15:55,686]: I can make them do that [01:15:56,986]: Then they come back to me and they say wow that’s really cool [01:16:00,586]: And I ran into a woman in the grocery store the other day who read my book and she says I didn’t know you were so funny [01:16:07,606]: I try to put a few jokes in there you know to keep people’s interests and so on [01:16:12,706]: So yeah so it’s been exciting for me to write the book and to have people like you and Rob notice it [01:16:20,766]: I’m very grateful for being able to talk to you [01:16:25,866]: I’ve been watching your podcast [01:16:28,166]: My son has been a big fan for a long time [01:16:30,606]: He yep yep and he yep [01:16:34,206]: Well I promise you that you haven’t bored anyone today Paul and if your son is a fan of the show that suggests even more about the quality of the genetics I’m sorry I’m very good [01:16:44,566]: I really appreciate you Paul [01:16:46,166]: Until next time [01:16:47,006]: Okay yeah well thank you yeah [01:16:48,626]: Okay take care [01:16:49,366]: Congratulations you made it to
