Fascinating! Grandmothers may also extend the juvenile period/characteristics of the young (neoteny), which is highly adventageous in complex human societies.

Thank you. And thanks for the info about neoteny. I didn't come across that, but it makes sense. Why is that good? More time to nourish and make a strong foundation for adulthood?
Yes, this variable appears to change depending on environmental pressures. The more complex the environment (new niche, variety of food sources, social changes), the more time is required for the young to reach maturity and adapt to it. In times of scarcity (simplicity), the young matures quickly so they can give birth before they die. I'm sure I'm mangling the idea, but it's something along those lines.
Interesting. I'll have to read more about that. Thanks
