"Studies of twins, family members, and adoptees together point to a significant hereditary contribution to intelligence scores. The search is under way for genes that together contribute to intelligence. Yet research also provides evidence of environmental influence. The intelligence test scores of fraternal twins raised together are more similar than those of other siblings, and the scores of identical twins raised apart are slightly less similar (though still very highly correlated) than the scores of identical twins raised together. Other studies, of children reared in extremely impoverished, enriched, or culturally different environments, indicate that life experiences can significantly influence intelligence test performance."
