Killer Whales Go Through Menopause, But Do They Get Hot Flashes?
LatestKiller whales are one of only three species on the planet to experience menopause, and scientists believe the evolutionary trait is a result of whales’ “unusual social structure,” in which their adult children never really leave them. (On a side note: what the fuck is day two of a whale period like?)
Humans, pilot whales, and killer whales are the only species to continue living long enough after they stop reproducing. Female killer whales finish up their childbearing years in their 30s and 40s, but they can live until they’re 90. Researchers from Exeter University and York University are currently studying why they have evolved to be so similar to humans. The theory is that it has to do with their social relationships.
