Thousands of genes are involved in intelligence, according to a new study which effectively shatters any hopes of eugenicists that babies can be genetically designed to be clever. In one of the largest studies of the human genome to date, a group of 253 scientists from around the world identified 74 genetic variants that are associated with the number of years spent in formal education. Humans' genetic make-up is believed to be responsible for at least 20 per cent of the difference in educational attainment between individuals, with the rest down to social factors and the environment in which they are raised. But the researchers found that the largest effect of any one genetic variant was tiny – just 0.035 per cent. This suggests that there must be at least several thousand of genes that are involved.
