Can we apply this to humans? If you look at how teen age sex activity has gotten to younger ages, and some groups such as ghetto people, who live in tough circumstances, have many babies at young ages, maybe mother nature gives us instincts that we’re not aware of. Maybe mother nature gives instincts towards reproduction to people in difficult situations, so that the species will survive.
It would be interesting to see if this correlates with the increase in abortions in the USA.
“and some groups such as ghetto people, who live in tough circumstances, have many babies at young ages, maybe mother nature gives us instincts”
In the case you mention, I’d say it’s the government giving instincts in the form of WIC and welfare payments.
It possible, I suppose. But its not working in Europe among “caucasian” folks whose birth rates are declining precipitously nor in Japan, a more closed society.
Europe might be explained that there are simply a lot of humans there and race doesn’t matter. Japan might also be the same thing: too many folk crammed into a small place.
Absent the social environment, your theory might have validity. Certainly here in our history, the age of birth mothers has risen as we moved away from isolated, rural living[eg Appalachia]: the tough circumstances you posit.
