New Scientist is carrying this article summarizing a new study in Rhesus monkeys that seems to confirm the results of a similar study in humans: mothering trumps genes. Careful study has revealed that children are much more likely to be aggressive and antisocial if they have a "short" version of a specific gene. However, both studies have now confirmed that the gene only "expresses" itself when the infant is reared in an abusive home.

So be sure to call your mom and thank her... she's the only one who kept you from growing into a homicidal maniac!
