Why do humans enjoy much longer life spans than other higher primates? Here's one reason: grandmothers. Anthropologists propose that earlier in our evolution, families with elder females especially thrived. The grandmothers helped care for children, ensuring greater health for everyone as well as a higher rate of reproduction than grandmother-less broods. Their longevity genes got passed on, creating more grandmothers. Lucky! Having older women around while growing up has been key to the success of many of us.
