Koko, the ape known for communicating in American Sign Language has just gotten more human, he just learnt a little human vocal and breathing behaviour. Researchers from the University of Wisconsin-Madison and the University of California took footage of the ape for 71 hours and found that the ape was able to breathe and use his tongue and lips to try to articulate. The researchers concluded that the actions of the ape had significance. “Each of these behaviours is performed in the context of particular manual action routines and gestures,” they wrote. Biologist E.O. Wilson said that Koko and other primates are actually helping us understand what it means to be human.
