Due to the lack of this special structure in the human throat, the ability to speak arose – study

The form of man we see today is the result of thousands of years of development. Human is the only creature present on the earth which is able to produce words in the throat and has the ability to speak. A new study has revealed how the ability to speak developed within humans. Scientists have discovered how changes in humans occurred over time that separated us from our ancestors. This new study says that after studying 43 species, it has been found that other species lack a part of the throat called the vocal membrane. This membrane or membrane is an extended part of the vocal cords that looks like a ribbon.

It has also been revealed in the study that humans cannot make sounds like monkeys, because humans lack a balloon-like structure in the throat called air sacs. The airsax is lacking, so that humans can make a steady sound and form words.

Primatologist Takeshi Nishimura of Kyoto University’s Center for the Evolutionary Origins of Human Behavior in Japan said that the more complex vocal structure in non-human primates is due to their inability to control vibrations with precision.

Study co-author and evolutionary biologist W. Tecumseh Fitch at the University of Vienna in Austria said that the vocal membrane is what allows other primates to produce loud and high-pitched sounds. But there are more breaks in his voice and there is a lot of irregularity.

to study Science in the journal published Has been done The study examined the anatomy of monkeys, including species such as chimpanzees, gorillas, orangutans and gibbons. Along with this, Old World monkeys such as macaques, guenons, baboons and mandrills have also been studied. The study also included New World monkeys such as capuchins, tamarins, marmosets and titis.
