Long-Living Whales Shed Light on Menopause

Females see offspring through to maturity

Share

(Newser) – Stumped scientists finally have a clue about the evolutionary purpose of post-menopausal women. Female killer whales—who outlive males by decades—stick around to nurture their kin through maturity, the Los Angeles Times reports. Similarly, human mamas may stick around to ensure their kids really, truly, don't need them anymore. Older whales, incidentally, are also more adept at raising strong kids.
