It might or might not. We have women having children now at ages that would be considered absolutely ancient 10,000 years ago. As we extend our lifespan, we seem to stretch out everything ... childhood, child bearing years, productive years, etc. My point is that, it doesn't matter, since we no longer submit to evolution's rules, anyway.
" To give an example of the way man operates compared to other animals, consider speciation, which, as we know, tends to occur when a small group of animals gets separated from the rest of the herd by some geological upheaval, population pressure, food shortage or whatever and finds itself in a new environment with maybe something different going on. Take a very simple example; maybe a bunch of animals suddenly finds itself in a place where the weather is rather colder. We know that in a few generations those genes which favour a thicker coat will have come to the fore and we'll come and we'll find that the animals have now got thicker coats. Early man, who's a tool maker, doesn't have to do this: he can inhabit an extraordinarily wide range of habitats on earth, from tundra to the Gobi Desert - he even manages to live in New York for heaven's sake - and the reason is that when he arrives in a new environment he doesn't have to wait for several generations; if he arrives in a colder environment and sees an animal that has those genes which favour a thicker coat, he says 'I'll have it off him!'"
