A new study shows that chimpanzees drum with regular rhythm when they beat on tree trunks. Previous research has shown that chimps have their own signature drumming style. A new analysis of 371 bouts of chimpanzee drumming demonstrates that the chimps clearly play their instruments -- the tree trunks -- with regular rhythms. This suggests that the ability to produce rhythm predates the last common ancestor of humans and chimpanzees, dating back more than 6 million years. Scientists believe that the drumming is a form of long-distance communication. The research was published Friday in the journal Current Biology.
