@imaji "Why are human females the only mammals to go through menopause? " - not the only mammals, see also Orca (This is Mastodon, your book may be interesting but also any cetacean related research must be correct) 🤪
@imaji Interesting... I think someone, at some point, should do some research on why it appears that there's been so much change in human sexuality in the past few decades. Are there any correlations to human events, inventions, etc.?
