Finding the key gene in the evolution of the human brain

What makes people smarter than other primates? American scientists claim they have found the answer.

When studying the human genome, scientists at the University of California in Santa Cruz found that the HAR1F gene evolved 70 times faster than the rest of the human code.

The HAR1F gene is one of the key genes that contributes to the formation of the cortex, particularly in terms of language and information storage. According to the study, the gene increased the size of the cortex by three times within a few million years.

HAR1F gene is present in mammals and birds. If there are not many differences between different animals, such as between chimpanzees and a bird with only two differences, then there are 18 differences between humans and chimpanzees.

According to Dr. David Haussler, the author of the study, all these differences have occurred during human evolution due to stress when climbing down from trees and walking on two legs.

The researchers hope to find the effects of this gene on the rest of the body.
