Scientists have identified 52 genes linked to intelligence in nearly 80,000 individuals, a significant advancement in the study of mental ability. The authors noted that the genes do not determine intelligence, and that their combined influence is miniscule, suggesting that thousands more are likely involved, The New York Times reported. However, the findings could allow scientists to conduct new experiments into the biological basis of reasoning and problem solving. Furthermore, it could help investigators determine the best interventions for children with learning problems.
