Do Animals Have Menopause?

The animal kingdom is full of strange reproductive strategies, but when it comes to menopause, humans are among the weirdest. The jury is still out on why few species experience menopause while most do not. Some researchers believe it has to do with the family structures in which both humans and certain whales live.

Dubbed the reproductive conflict hypothesis, some researchers refer to this as the "Father of the Bride 2" hypothesis, because it bears resemblance to the predicament in which actor Steve Martin finds himself in the 1995 comedy where both his wife and daughter are pregnant at the same time.
