There are a lot of factors that contribute to human survival but grandparents are apparently one of them. In the past 55 years we’ve managed to find out that one big reason why we can now live so much longer than other species is thanks to our grandmothers.
Our grandmothers are often unappreciated because they’re not the primary caregivers for their grandkids, yet without them, many families wouldn’t have been able to make it as far. Let’s shine the spotlight on them for a second to notice the impact that they have on their grandkids.

The Grandmother Effect
The “grandmother effect,” was a term that started around the 1960s when researchers were trying to understand human survival. They found that grandmothers played a big part in raising children. From a genetics point of view, since the grandchildren carry a portion of their genes, grandmothers will instinctively want to help those children survive.
What happens is that grandmothers help alleviate some of the responsibilities of taking care of the child, especially in the early and difficult years which then helps those children have longer lives and even encourages the mother to have more children. Some studies have even linked being in grandparents’ care wot better grades and fewer behavioral problems.
