An international group of 100 scientists has studied 178,076 siblings to estimate the effects of genetics and environment on health and social outcomes. Their findings are published today (May 9) in Nature Genetics. They found that the genetic factors on more social traits—like educational attainment, age of first child and depression—are strongly influenced by either the family or social environment. In contrast, the genetic influences on more biological traits—such as cholesterol and BMI—were found to be less socially influenced.
