Running Made Us Human
Endurance running, unique to humans among primates and uncommon in all mammals other than dogs, horses and hyenas, apparently evolved at least two million years ago and probably enabled human ancestors to hunt and scavenge for food over large distances. And that, in turn, probably proved decisive in their pursuit of high-protein food for development of larger brains.
And the sentence most likely to induce snickering:
Earlier human ancestors, like chimpanzees today, had pelvises that could support only a modest gluteus maximus, nothing like the strong buttocks of Homo.
