And I think the reason is, is because it was more adaptive to stop at a certain age because children were becoming, you know, more helpless, more altricial is the word. And, uh, their, their, their period of dependency lasted a lot longer.

Yeah. Um, so women stopped reproducing directly in, in their forties because as children were becoming more and more needy, uh, and, uh, The chances of them surviving and being successful, if you died before they were 10 years old or so, became very, very, very low. And so it became adaptive to stop and nurture the last child that you had maybe when you were 40 years old. And then...

So that would keep natural selection stronger to later ages that need to reproduce indirectly by helping children you already had produced. That held off the ravages of old age. And so the whole thing just kept increasing so that eventually we live long enough to take care of our children's children. And so the grandmother hypothesis sort of explains that.

why we live to later and later ages, but also why we don't directly keep reproducing during that time.

I was listening to one of your podcasts was Peter at T and he talks about slow death and long death. And, uh, you know, the slow death wasn't, wasn't there. You, you were relatively fit and then something got you. So you weren't a burden on everybody, uh, back, back in the day like that. And, and so even, even for males, you know, you, you brought up a good point. Um,

You know, 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. You know, like where the watering hole doesn't go dry when we're hunting for such and such and so on.

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.

Well, I think that covers it in terms of the sort of the sociology of it, but we're out of alignment with, in terms of infectious disease exposures and things like that, with you know, with our daycare centers and so on, stuff like that. Kids, uh, experience different degrees of, of illness, uh, uh, different types of germs, different, uh, uh, immune system, developmental trajectories and so on.
