PHILADELPHIA — A male gorilla at the Philadelphia Zoo is taking a stand against dirty hands by opting to walk on two legs. When Louis has his hands full of tomatoes or other snacks, he walks upright like a human to keep food and hands clean, rather than the typical gorilla stance of leaning forward on his knuckles. The nearly 500-pound, 6-foot-tall primate crosses it like a tight rope to avoid getting dirty. Stern says it’s “pretty unusual” for gorillas to walk around upright. In the wild, Western lowland gorillas like Louis might do it for a few seconds to reach food or wade into swamps.
