Chimpanzees drum with regular rhythm when they beat on tree trunks, a form of ancient communication
Shampanzi drum with Regular rhythm When they overcame tree trunks, a new study appears.
Chimpanzee The last joint ancestor participated about 6 million years ago. Scientists suspect that this old grandfather should be a drama player – using beats to communicate.
“Our ability to produce rhythm-and use it in our social worlds-this is something that people are a human being.”
Previous research has shown that chimpanzee has its own drum style. A new analysis of 371 chanti -drums shows that chimpanzee “clearly plays their tools – tree trunks – with regular rhythms.”
When adhering to the forest, chimpanzees often hold long support roots of rainforest trees. Sometimes, they score several times to create low -frequency sounds that can be heard for one or more kilometers through the forest.
Scientists believe that the process of drums is a form of long -distance communication, and perhaps to alert chimpanzees as a chimpanzee or the direction he travels to.
“It is a socially registration method,” Hobaite said, adding that all chimpanzees “are” an individual signature – a pattern of rhythms that allows you to know who produces this drum. “
The new work has shown that chimpanzees are from different regions of Africa with a clearly different rhythms, with Western chimpanzees prefer a more rhythm even while Eastern chimpanzee uses short and long periods between rhythms. The research was published on Friday in the magazine Current biology.
It is known that chimpanzees use tools like rocks to break open nuts and sticks to the “fish” termites from their hills. Researchers say the roots of trees can also be tools.
Participating author Catherine Crocford, a primitive specialist at the CNRS Institute of Knowledge Sciences in France, said the champeshm are selective about the roots they see. Some shapes and wood varieties create sounds that move well through a dense forest.
She probably said the drum “is a very important way to communicate.”
