So putting aside that all female problems are caused by men, the conclusion seems a real stretch.

Let's suppose that all of these males that want young females mate with all of the young females. Since they don't know which of these young women will menopause sooner than the other ( and don't care ) how is this causing selection among the population? Answer - it doesn't affect the menopause selection at all.

In sparely populated societies which was the norm until very recently in human evolution, it is most likely that males mated with every female, every time when presented the option. How did that cause selection bias? It didn't.

Most men, given the choice between younger vs older will choose younger but most men will also choose sex with an older women over no sex. This probably means that all women where getting enough sex to get pregnant which would bias the evolution towards extending time before menopause because that would be the women having babies at 50 or 55. This is the question you should be answering - why did women choose to stop being fertile at 50 or 55?


Child birth is a naturally dangerous process and very taxing on a women's body. Most likely this is self preservation or just the fact that until a couple of hundred years ago, few people lived past 50 years old.
