Musicality may have emerged in a common ancestor of chimpanzees and humans, since both species share similarities in the way they stagger.
Catherine Hobaiter of the University of St Andrews, the United Kingdom, and his colleagues examined 371 examples of drums of two or four subspecies of chimpanzees of Africa: the western chimpanzee (western chimpanzee (Troglodytes Verus bread) and the eastern chimpanzee (Troglodytes bread Schweinfurthii).
They use their hands and feet to produce rapid fire drums, or in the roots of the buttresses and mainly when they rest, while traveling or false threats are displayed.
Hobaitar says that while chimpanzees staggered regularly, tropical jungles are really difficult places to carry out studies and for some of the populations, they have tasks to collect the data.
Possible, researchers found that chimpanzees wobm up much faster than most humans. “The longest drum we recorded was in 5 seconds, while the shortest one was less than 0.1 seconds,” says Hobaitar. “But chimpanzees will also repeat thesis fighting several times, especially when they travel.”
Despite the differences between chimpanzee and the human battery, the chimpanzees show some of the “basic components of the human musical rhythm,” says the Vesta Eleuteri team member at the University of Vienna, Austria.
“Drume with rhythm, instead of random, and are a typical pace observed in musical cultures called isochrony, which consist of successes that are regularly spaced, such as the margin of a clock”, Sheer’s. “We also discovered that the two subpecies of Eaastern and Western Chimpanzee who live on the opposite sides of Africa with different rhythms.”
She says that Eastern chimpanzees alternate short and long spaces between their battery blows, while Western chimpanzees space them uniformly. These chimpanzees also stagger faster, use more blows and begin to stagger before in their distinctive pants shot.
Miguel Llorente of the University of Girona in Spain says that the idea that different subspecies show different drum styles is fascinating. “Open when thinking about these patterns not only as individual peculiarities, but enhanced as cultural differentials in how groups use battery as a communicative tool.”
We already know that the rhythm is essential for human social behavior, either in music and dance or in the round trip of a conversation, says Hobaitar. “We do not mean that the Chimpanzee battery shows the sophistication of modern human musical rhythms. But this is the first time we have been able to show that they share the same rhythmic construction blocks, so it makes it much more Befy Befy Befy Befy Befy Befy Befy Bef: Human.
“Until recently, it was argued that the rhythmity was exclusive to humans,” says Gisela Kaplan of the University of New England, Australia. “Now we have a lot of evidence that this is not the case.”
