On the plains of New Mexico, a band of elite marathoners tests a controversial theory of evolution: that humans can outrun the fastest animals on earth.

The pronghorn is the second-fastest animal on earth, while the men are merely elite marathon runners who are trying to verify a theory about human evolution. Some scientists believe that our ancestors evolved into endurance athletes in order to hunt quadrupeds by running them to exhaustion. If the theory holds up, the antelope I’m watching will eventually tire and the men will catch it. Then they’ll have to decide whether to kill it for food or let it go.
