Gibbon species have the ability to sing like professional opera singers

A new study shows that gibbons can control vocal cords as professional opera singers.

Scientists have found that gibbons easily use the same techniques as a professional opera artist after hearing high-pitched cries when they call other animals.

A study in Japan also provided evidence that unusual physiological similarities between gibbons and humans.

'The complexity of human speech is unique among primates because it requires a lot of soft sounds created by the rapid movement of the constituents' , quoted the researcher. Rescue Takeshi Nishimura from Kyoto Primate Research Institute.

He said: 'Our voices evolve through a series of special changes in vocal anatomy. However, we have shown that the gibbon cries use a vocal mechanism like an opera soprano. This has revealed a similarity between apes and humans. '

The leading group, Nishimura researcher, analyzed 20 "cool and noisy" calls of white-handed gibbons, in normal environments and 37 calls in helium-containing environments.

Helium acts to change the tone of the voice, making the sound when emitted higher than normal because the helium gas is thicker than the air, pushing high sound resonance frequencies but not changing the original sound.

Research shows that, like humans, the origin of the sounds of gibbons in the larynx will be separated from the vocal tools used to transform sound.

Moreover, the study also showed the ability to control vocal and vocal cords when gibbon cries - an important ability of a professional opera singer to master the soprano.

'This gives us a new assessment in the evolution of gibbon cries and demonstrates that the physiological origin of human language is not unique' , Nishimura said.
