JOHANNESBURG, South Africa, Aug. 14 (UPI) -- Researchers say they have obtained the first video-based observation of swimming and diving by apes, a behavior previously thought distinct to humans.
Zoos have for many years used water moats to confine chimpanzees, gorillas or orangutans, who often drowned if they ventured into deep water, leading some researchers to conclude swimming was an exclusively human activity among primates.
