4、vironmental differences between people pile up in life,”says RobertPlomin. “What we found was quite amazing, and goes in the other direction.”Previous studies have shown variations in intelligence are at least partly due to genetics. To find out whether this genetic contribution varies with age, Plo
5、mins team pooled data from six separate studies carried out in the US, the UK, Australia and the Netherlands, involving a total of 11,000 pairs of twins. In these studies, the researchers tested twins on reasoning, logic and arithmetics to measure a quantity called general cognitive ability, or “G”.
6、 Each study also included both identical twins, with the same genes, and fraternal twins, sharing about half their genes, making it possible to distinguish the contributions of genes and environment to their G scores.Plomins team calculated that in childhood, genes account for about 41 percent of th
7、e variation inintelligence. In adolescence, this rose to 55 percent； by young adolescence, it was 66 percent. No one knows why the influence from genes should increase with age, but Plomin suggests that as children getolder，they become better at exploiting and manipulating their environment to suit
