Humans are the animal world’s best distance

Humans are the animal world’s best distance runners…we can run long distances relatively fast without overheating. “Once humans start running, it only takes a bit more energy for us to run faster, Lieberman said. Other animals, on the other hand, expend a lot more energy as they speed up, particularly when they switch from a trot to a gallop, which most animals cannot maintain over long distances.” (via beebo)
