Chimpanzees spontaneously dance to music

A pair of researchers at Kyoto University has found that chimpanzees will spontaneously dance to music. In their paper published in Proceedings of the National Academy of Sciences, Yuko Hattori and Masaki Tomonaga describe observing spontaneous dancing in chimps and how one chimp behaved when tested on dancing tendencies.
