Chimpanzees played the drum with rhythmic intention: which one is the roots of music in humans?
The results of the new study gives credibility to the theory that there are musical elements in humans before the division between humans and chimpanzees 6 million years ago.

Like humans, chimpanzees can play the drum rhythmically, and two subspecies of these primets living in East and West Africa have their own unique way, according to one Published this week in current biology.
Previous scientific studies have shown that chimpanzees have hit their feet in the roots of the trees, which create sounds that allow them to communicate at far.
In the drumming trees of these primets It helps to understand the source of music in humans. But so far it is difficult to collect enough useful data in the middle of the wild cacophony.
“Finally, the chimpanzee is not only a rhythmic, coincidence, but also randomly, but the main author of his study, Vienna University, France-Presse (AFP), told Westa Eletaria.
Over the century of verified observation data
The results of this study They give credibility to the theory that there are musical elements in humans before the division between human beings and chimpanzees 6 million years ago.
After successfully filtered unwanted sounds, A group focused on 371 high quality drum samples recorded in 11 chimpanzees In six groups living in tropical or Savanna forest areas of East and West Africa.
Your analysis shows it Chimpanzees are not random with the frequency frequency of their beats with a strong rhythmic intention.
They also appear Variations between subspecies: Chimpanzees living in West Africa produce beats in a more systematic period, and those in the east are substituted for a long and short period of time.
In the west, too They are more frequently playing the drum, placed at high speed and use previous percussion in their voices.
Researchers have not yet recognized what these differences can describe, but it is referred to Reflects differences in social dynamics.
The rapid and PRD of Western chimpanzees reflects greater social integration, highlighting the authors, claiming that they are usually less aggressive with people outside the group.
In contrast, the most irregular rhythm of the eastern chimpanzees is associated with more micro -profictions, which can be used to identify peers in more dispersed habitats.
Now the Hobiter wants to continue studying this data to find out if there are intergeneration variations in the rhythms of the same group.
“Music is not just a difference between different music styles, but a musical style like rock or jazz develops over time,” he said.
“We have to find a way to distinguish between group differences and intergeneration differences in the question of whether it is socially learned or not. Is there a person who receives it with a new style and the next generation?” Asked.
