It doesn't matter how much you learn, half of human intelligence comes down to your genes, according to scientists from the University of Edinburgh.
They say that the difference in intelligence is made by the genes that people are born with, but that in addition to genetics, environmental factors also play a big role: parents, diet and lifestyle, and exposure to chemicals in the prenatal period.
Scientists have determined that a combination of rare and common genetic variants accounts for at least half of the difference in people's intelligence. Scientists now know about 52 genes that are associated with intelligence, 40 of which were discovered relatively recently, "Srna" reports.
Research at the University of Amsterdam has led to the discovery of new genes and biological routes to intelligence. Many people with these genes have been found to have other traits in common, including being tall, thin and likely non-smokers. They are also less likely to suffer from Alzheimer's, depression, schizophrenia and obesity.
