Recent research has illuminated why menopause, a rare trait among Earth's species, evolved in humans and certain whale species, including killer whales, orcas, narwhals, and four other toothed whales. A study published in the journal Nature suggests that menopause in toothed whales may have evolved as a strategy to increase the total lifespan of these creatures. The findings indicate that the evolution of menopause enables older females to assist younger generations in surviving by avoiding competition with daughters and granddaughters for mates. This research, examining five species of whales that undergo menopause, provides insights into the evolutionary benefits of menopause, potentially explaining its presence in humans and these marine mammals.
Researchers looked at five species of whales that go through menopause, including orcas and narwhals. Their findings, published Wednesday in the journal Nature, suggest the trait evolved so that older females can help care for younger generations. https://t.co/OLzdEtXflV
