Adapted for Running?



Daniel Lieberman is an anthropologist at Harvard University in Cambridge, Massachusetts, and an expert on the evolution of human locomotion. In an email exchange, he said the "prints unambiguously indicate that by 1.5 million years ago H. erectus had a human-like foot."

Other human ancestors such as the australopithecines may have also been efficient walkers, he said. But a more modern foot anatomy with spring-like arches and short toes is important for running, which may have contributed to the success of H. erectus.

(Related: "Humans Were Born to Run, Fossil Study Suggests.")

"I would be surprised if this were not the case," Lieberman said. "Because how could H. erectus have hunted more than a million years before the invention of tipped spears—as we know it did—without the ability to run well?"
