Study: Gorillas go through menopause

A study of gorillas at 17 North American zoos, led by Chicago's Brookfield Zoo, is the first to document gorilla menopause, according to researchers who were not involved in the study.

The findings may help zoos improve how they care for aging female gorillas and change the way evolutionary biologists think about menopause in humans.

Researchers think this may serve to refute the "grandmother hypothesis" which posits menopause evolved to give grandmothers time to help care for the grandchildren. Gorilla grandmas don't hang with the young'uns, so it might just be a result of living longer.
