born to run

Evolutionary bio and marathon running, at Seed magazine.

We know that roughly 2 million years ago, Australopithecus, with its tiny brain, hefty jaw and diet of rough, fibrous plants, evolved into Homo erectus, our slim, long-legged ancestor with a big brain and small teeth suited for tearing into animal and fruit flesh. Such a transformation almost certainly involved a reliable supply of calorie-laden meat, yet according to the fossil record, spear points have been in use for 200,000 years at most, and the bow and arrow for only 50,000 years, leaving an enormous stretch of time when early humans were consuming meat without the use of tools. Lieberman believes they ran their prey to death, often called “persistence hunting.”

Interesting and usable.
