The mysterious Gene made the ancient people talk

For many years, scientists still have a headache because of a question. What has caused our ancestors to escape from human chaos and evolve so strongly?

Now, researchers believe they have explained the missing link in that evolutionary chain: a double gene named SRGAP2, which appeared in the 'gibbon' about 2.5 million years ago. This gene helps our brain cells move faster, connect more broadly, so that the brain becomes more complex and evolved.

Scientists believe they have found links
missing in the evolutionary chain of human ancestors.

Presented in Cell magazine, the authors believe that this process will help explain why humans soon formed voices, complex behaviors and mastery of tools, while gibbons did not.

The original gene and copy of SRGAP2 produce identical brain development proteins. However, a copy of SRGAP2 helps neurons develop longer dendrites, thus obtaining faster, more efficient electrical impulses from other cells.

'It seems that this mutation point has helped the Australopithecus ape transform into Homo Sapiens' , said Professor Franck Polleux of Scripps, California Research Institute on DailyMail. 'SRGAP2 is one of about 30 duplicated genes in humans after we' split 'from the gibbon'.

Agreeing with this view, University of Washington geneticist Evan Eichler believes that this is the factor that causes breakthrough changes in the human brain and brain function.

The authors also hope that, in addition to helping explain human origins, the findings also provide clues to treat neurological disorders such as autism, epilepsy .
