Nature or nurture? It may depend on where you live

In a study published June 12 in the journal Molecular Psychiatry, researchers from the Twins Early Development Study at King's College London's Institute of Psychiatry studied data from more than 6700 families relating to 45 childhood characteristics, from IQ and hyperactivity to height and weight. They found that genetic and environmental contributions to these characteristics vary geographically in the UK and have published their results online as a series of nature-nurture maps.
