Beg for Food
Other primates are particularly astute at our gestures. "That's why ape communication often looks incredibly human to us," de Waal said. "They beg for food with an open hand (the way human beggars do in the street), have aggressive gestures that look very human, stroke, and touch and hug just like humans, and so the gestural repertoire looks extremely human to us."
A 2007 study of our closest living relatives, chimpanzees and bonobos, showed the primates were more versatile with hand and foot gestures than with facial expressions. A juvenile chimpanzee in the study showed such hand-waving savvy by combining the reach-out begging gesture with a silent bared teeth face — all in an effort to reclaim food. The research, published in the Proceedings of the National Academy of Sciences, suggested humans were communicating with sign language long before speaking.
Another peculiar gesture found in primates: Zookeepers from a British zoo reported some of the mandrills there were covering their eyes with one hand (shown here) to gesture to other monkeys, "do not disturb." In 2011, researcher Mark Laidre of the University of California, Berkeley, said he believes the sign may be evidence of social culture among the animals.
