Grandmothers are essential!

Today many older women feel marginalized once they reach menopause. But research suggests that far from being a burden to societies, grandmothers have played an important role in the evolution of human longevity. Studies of modern hunter-gatherers in Tanzania, Venezuela and Eastern Paraguay — societies that offer insights into how humans evolved — consistently show that Grandma is doing much of the work.

Researchers have even measured the muscle strength of men and women in these communities and weighed the baskets and bundles carted around by them. Often, the scientists find, women in their 60s are as strong as women in their 20s. “It’s the women over 40 who are carrying the heavy loads,’’ said researchers.

The research is the basis for the grandmother hypothesis that may help explain why menopause occurs. The basic idea is that an end to a woman’s reproductive years allows her to channel her energy and resources into caring for her children and grandchildren, thereby providing her descendants with a survival advantage.

In hunter-gatherer cultures today, said researchers, “women are strong and economically productive into their 60s….Women are not being helped along by others. The flow of help is going into the other direction.”
