Scottish scientists discovered more than 500 genes , who are responsible for the development of intelligence, having carried out the most ambitious research in this field, reports The Herald .
During the study, scientists compared the DNA of 240,000 people from around the world and found 538 genes related to intelligence, which is 10 times more than researchers could find in previous studies. Scientists have also been able to detect 187 regions in the genome related to thinking skills.
“Intellect is a hereditary trait with close and family heritability assessments indicating that approximately 50-80% of differences in intelligence can be attributed to genetic factors,” said one researcher David Hill.
In addition, the researchers found that the presence of “genes of intelligence” reduces the risk of Alzheimer’s disease, depression, schizophrenia and obesity.
The authors of the study are concerned about the moral side of their discovery, which in fact allows to “model” the future child at the gene level. The ability to choose embryos based on their “intelligence genes” can lead to a loss of diversity, scientists say.
