Killer Whales Undergo Menopause, and Scientists Now Know Why: Data suggest menopause evolved to enable older female whales to help younger generations survive, and how researchers made a cellular map of the developing human heart
Menopause may help whale species survive: Female short-finned pilot whales, orcas, false killer whales, narwhals and beluga whales all experience menopause and live an average of 40 years longer than similar-size females of other whale species, researchers reported in the journal Nature. Female toothed whales are known to share food and guide their pods to food sources, suggesting that menopause enables the species to help ensure their families’ survival without continuing to reproduce, said researcher Darren Croft, Executive Director of the Center for Whale Research.
