I have run many marathons but am especially excited to be running 26.2 miles through the streets of San Francisco on July 31 to raise money for The Leakey Foundation. In fact, running for the Leakey Foundation—which supports research on human evolution— couldn’t be more appropriate because we humans evolved to run in order to help each other survive.

The evidence that we were not only born to run but also evolved to run comes from abundant fossil and archaeological data. These finds show that by 2 million years ago our early African ancestors had evolved adaptations such as short toes, arches in the feet, long Achilles tendons, and big buttocks that made them superlative long distance runners. We also lost our fur and developed the ability to dump heat by sweating. These and other features, which we still retain, helped early humans first scavenge and then hunt large animals millions of years before the invention of projectile weapons like the bow and arrow. An especially important benefit of running was the ability to chase animals over long distances in the heat, driving the prey into a state of heat exhaustion. Early human hunters then shared the meat, helping feed their families and each other.

Thankfully, none of us on Sunday will chase the bisons watching us halfway through the course, but as we struggle through Golden Gate Park, it might help to remember that today we are running for same fundamental reason as our ancestors did 2 million years ago in the savannas of Africa:  to help each other. Two million years ago we ran to hunt and provision each other with sustaining food; today we run to raise funds for charities including The Leakey Foundation, as well as to promote fitness and to build community. It really is true that we run to make the world a better place.
