For Human Evolution, Root-Gathering Grandmas May Have Been More Important Than Man The Hunter : Goats and Soda : NPR
So if dad wasn't bringing home the bacon, who was? After spending a lot of time with the women on their daily foraging trips, the researchers were surprised to discover that the women, both young and old, were providing the majority of calories to their families and group-mates.
Mostly, they were digging tubers, which are deeply buried and hard to extract. The success of a mother at gathering these tubers correlated with the growth of her child. But something else surprising happened once mom had a second baby: That original relationship went away and a new correlation emerged with the amount of food their grandmother was gathering.
Hanging with the Hadza, eatin' them tubers. I don't think the Vikings would have dug it though.
