You know how among primitive humans men did the hunting and women did what women are supposed to do — stayed "home" taking care of the children and the home front while their brave men brought home the bacon? We all know this is how things worked back then.
But it appears what we have "known" doesn't fit the facts. As Cara Ocobock and Sarah Lacy report,
"Mounting evidence from exercise science indicates that women are physiologically better suited than men to endurance efforts such as running marathons. This advantage bears on questions about hunting because a prominent hypothesis contends that early humans are thought to have pursued prey on foot over long distances until the animals were exhausted."
