Chimps on Treadmills
In a study published in the Proceedings of the National Academy of Sciences, Sockol and Raichlen compared how much energy humans and chimpanzees use while walking. Five chimpanzees were taught to walk upright on treadmills while wearing oxygen masks. Raichlen said that the training was done over four months, but only when the chimps were cooperating. "These guys are smart enough that they would hit the stop button on the treadmill when they were done. If they didn't want to walk on the treadmill, they'd just hit the stop button or they'd jump off."
