A new study from McMaster University has concluded that men are partially responsible for the existence of menopause in women. Menopause is very much a human phenomenon. It’s very very rare in other species.
So why does it occur? The researchers think that men have preferred younger women throughout history. This is called ‘preferential mating.’ According to this theory, women will put all their procreation resources when they’re younger. When those are spent, menopause happens.
Other researchers, however, think it’s the complete opposite: Men developed a preference for younger females because older ones went through menopause. Either way, it seems like men have a lot to do with that pesky female problem.
