more than 500 genes that are linked to intelligence


More than 500 genes associated with intelligence have been identified in the largest study of its kind.
Researchers used data from the UK Biobank, comparing DNA variants from more than 240,000 people. Their analysis identified 538 genes linked to intellectual ability, and 187 regions of the human genome that are associated with thinking skills. Some of these genes are also linked to other biological processes, including living longer.
However, even with all these genes, it’s still difficult to predict a person’s intelligence from their genomes. When they analysed the DNA of a group of different people, the team were only able to predict 7 per cent of the intelligence differences between those people.
It is thought that around 50 to 80 per cent of variation in general intelligence between people is down to genetics. But environment plays a role too. Well-nourished children brought up in safe, unpolluted and stimulating environments score better in IQ tests than deprived children, for instance.
