In evolutionary theory, we have this thing we tend to look for, called parsimony. What fits the data best? Fertility into old age is part of our ancestral history if menopause is to eventually evolve, yes? Then probably our closest living relatives, like say chimpanzees, don’t have menopause, unless it independently evolved more than once of course. Right.

Baseball players reveal how humans evolved to throw so well. A catapult-like mechanism allows energy to be stored in shoulder and torso, a video study of pitchers reveals.
