Hunting Key to Human evolution
Long-distance running may have been a driving force behind evolution of the modern human body, scientists say.
American researchers said humans began endurance running about 2 million years ago to help hunt for prey, influencing the development of the human body.
Previous studies have suggested running was purely a by-product of walking.
But the study, published in Nature, said humans evolved big buttocks, a balanced head and longer legs to help gather food.
Professor Dennis Bramble, of the University of Utah, and Professor Daniel Lieberman, of Harvard University, reported that early human beings may have needed to run long distance to help hunt prey or scavenge animal carcasses on the African savannah.
Without the development from running, humans would be much more like apes with shorter legs, smaller heads and a hunched posture, the scientists said.
What a great day to publish this! Just think without Hunting we would all look like Robin Cook!
