When volunteers were shown videos of apes using gestures, they were able to correctly interpret most of them.

Dr Kirsty Graham, St Andrews University

"Our new study demonstrates that people can understand great ape gestures. So, all of this together gives us more confidence that this was a communication system that would have been used by our last common ancestor."

柯斯蒂·格雷厄姆  博士      圣安德鲁斯大学

“我们的新研究表明，人们可以理解猿类的手势。因此，所有的研究结果都让我们更加坚信，这种手势是一种交流方式，人类与黑猩猩及倭黑猩猩最后的共同祖先曾用它相互沟通。”
