Smart folk may have lofty genes

Meanwhile, researchers have discovered 40 new genes for the intelligence trait, finding that many of the people who possess these are tall, thin and nonsmokers. Scientists hope the findings can provide new biological insights into brain function and understanding and help to define the genetic component of IQ. It is believed that up to thousands of genes play a role in human intelligence, with most contributing only a minuscule amount to a person’s cognitive ability. The same genes, however, are also associated with a larger head circumference at birth, living longer and autism. Trump may be with us for a while longer yet.
