Scientists: Intelligence linked to 52 'smart genes'

Links to intelligence have been found in 52 genes, 40 of which have been identified for the first time, new research has revealed. However, the discovery does not mean that the genes determine genius.'

On Monday, a team of 30 scientists, led by Danielle Posthuma of VU University Amsterdam, released a new study in the journal Nature Genetics announcing "new insight into the genetic architecture of intelligence."

"For the first time, we were able to detect a substantial amount of genetic effects in IQ," Posthuma told AFP. "Our findings provide insight into the biological underpinnings of intelligence."

For the study, researchers used various tests to measure intelligence in 13 different groups of people. They looked for genetic markers linked to intelligence across 78,308 adults and children of European descent, including a database of...
