Chimpanzee groups drum with distinct rhythms

New research from a team of cognitive scientists and evolutionary biologists finds that chimpanzees drum rhythmically, using regular spacing between drum hits. Their results show that eastern and western chimpanzees -- two distinct subspecies -- drum with distinguishable rhythms. The researchers say these findings suggest that the building blocks of human musicality arose in a common ancestor of chimpanzees and humans.
