@oakreef Interesting! Both long lived, highly social, cultural.
I've seen it convincingly argued that menopause is a social trait, allows the most experienced members of a group to share attention/experience with the youngest generation. In humans, given the extraordinarily high mortality rate of women in childbirth, probably also drastically improved life expectancy for the most valuable minds in a community.
Nope, menopause is common in primates, unless you carefully define it to be exclusively human. The hormonal changes leading to reduced or stopped menstruation, and either reduced fertility or the end of fertility, occurs during in monkeys and great apes. The first studies of this were in the 80's.
As usual, there are always people who want to draw definitions of things so that humans come out as special magical beings different from all other animals...
