Researchers have found evidence suggesting wild chimpanzees in Uganda's Kibale National Park go through menopause, shedding light on the evolution of this rare trait in humans.

Researchers studied chimpanzee and monkey anatomy to better understand how humans evolved to have flexible shoulders and elbows.
