Two new studies reported in the Proceedings of the National Academy of Sciences that say babies who are breast fed and carry a particular gene get an IQ boost. The two studies of breast-fed infants involved more than 3,000 children in Britain and New Zealand. The average increase was nearly 7 IQ points if the children had a particular version of a gene called FADS2.

"Our findings support the idea that the nutritional content of breast milk accounts for the differences seen in human IQ," said Terrie Moffitt, a professor of psychological and brain sciences in Duke University's Institute for Genome Sciences and Policy. "But it's not a simple all-or-none connection: it depends to some extent on the genetic makeup of each infant."

In the end, the study says that the argument of nature versus nurture has a result that both benefit the growth of children.
