Did you know that killer whales are the only mammals besides humans to experience menopause? Scientists attributed the phenomenon in one ecotype (a subset of a species) of killer whales to “grandmothering,” which allowed mothers to conserve energy by getting help from their menopausal relatives.
But a new study shows that older killer whales in an ecotype where mothers leave their family when they mature also experience menopause—i.e. the menopausal whales aren’t hanging around with the younger family members providing help. Which raises the questions of why do these whales live well beyond their reproductive years? Why did menopause evolve in these whales? We will have to stay tuned. (This is why I love science!)
