The vast majority of mammals remain fertile until the end of their lives. Humans and some species of whales deviate from that norm and do go through menopause. Now, research published in Science reveals that menopause exists in female chimpanzees, too, and that it lasts for a fifth of their adult lifespan. To reach these conclusions, the research team observed 185 female chimpanzees between 1995 and 2016 in Uganda's Kibale National Park and measured hormone levels in urine samples from specimens of various ages.
