"More than 500 genes linked to intelligence have been identified in the largest study of its kind. Scientists compared variation in DNA in more than 240,000 people from around the world, to discover which genes are associated with intelligence. Researchers identified 538 genes that play a role in intellectual ability. They also found 187 regions in the human genome that are linked to thinking skills.

Using these genetic discoveries, scientists next predicted seven per cent of intelligence differences in an independent group of individuals using their DNA alone. "Our study identified a large number of genes linked to intelligence. Importantly, we were also able to identify some of the biological processes that genetic variation appears to influence to produce such differences in intelligence, and we were also able to predict intelligence in another group using only their DNA," says Dr. David Hill.
"We know that environments and genes both contribute to the differences we observe in people's intelligence. This study adds to what we know about which genes influence intelligence, and suggests that health and intelligence are related in part because some of the same genes influence them," says Professor Ian Deary."
