How much a person’s intelligence is governed by nature or nurture has been debated throughout the ages. A new piece of research has thrown some interesting evidence into the mix, identifying over 500 genes that appear to be linked to sharp intelligence.
The research is the largest study looking at how genes and intelligence are linked to date. Using the heaps of data gathered by the UK Biobank, scientists at the University of Edinburgh, the University of Southampton, and Harvard University compared DNA variants in over 248,000 people from across the world.
As they explain in the Nature journal Molecular Psychiatry, they managed to find 538 genes that play a role in intellectual ability, along with 187 regions in the human genome that are linked to cognitive skills.
