Orangutans: Nature's Most Energy Efficient Mammals


A team of researchers in the United States of America have carried out a study to determine how apes expend energy. That was the first study ever conducted to study apes in this manner. It found that the orangutans are the lowest expenders of energy, not only among apes but also all other mammals. Taking body masses into consideration, these animals use even less energy than sedentary (couch potato) people.
Although the researchers confined orangutans living in both indoor and outdoor habitats, the animals were involved in as much activity as their free-range counterparts living in the wild. According to the study's lead author, Herman Pontzer, the animals show a "remarkably low energy use." He compared it to discovering sloth in the family tree. Herman is an assistant professor of anthropology in Arts & Sciences at Washington University.
