We were born to run

Before bows and arrows and before horses were tamed, we did “persistence hunting” where we ran kudu, wildebeest and zebra into exhaustion. These animals can’t pant when they gallop. They overheat. People would find a big animal and chase it till it collapsed. You need no technology to do this, just the ability to run long distances, which all of us have. You can see proof of this capability every November when 45,000 people run for many hours through the streets of New York.- Dr. Daniel Lieberman, an evolutionary biology professor at Harvard, from a story in the New York Times
