Men’s Evolutionary Role
I love BBC Health News and find the most amazing stories there, things I don’t see anywhere else. Today’s has to do with women living longer, and studies on aging.
Women, not men, ensure the success of future generations, work suggests.
Grans surviving beyond the menopause appeared to increase the likelihood that their own children went on to have children, a Sheffield team found.
Yet grandfathers had very little influence on their offspring’s reproductive success, Proceedings of the Royal Society B reports.
But experts were quick to stress that both grandparents play a vital role in families and society.
The Sheffield University authors reason that women thrive following the menopause from caring for their own children and grandchildren.
In their study, grandmothers gained two extra grandchildren for every 10 years they survived beyond the menopause.
This link was not found with aged granddads, however.
Instead, the scientists say the “evolutionary” argument for a man’s survival to a ripe old age is to continue to churn out sperm and procreate.
