Did you know that other than humans, killer whales and pilot whales are the only known female animals or species to stop breeding and experience menopause?
Recently, a study conducted by both the University of Exeter and the University Cambridge, determined that there was a link between these species that may prove to be a valid explanation as to how menopause evolved in humans.
Typically, the male leaves the females to raise the young while they venture out – sometimes, never to return – to continue breeding.
Although different in regards to social structure, both the female human and a female Killer Whale or Pilot Whale become more related to those around them as they age and thus, the older female quits breeding to ensure that their younger offspring have resources to helping guide the young.
