Study shows you can inherit dad's fears

SCIENTISTS have shown for the first time that fear can be transmitted from a father to his offspring through his sperm alone, in a ground-breaking study into a new kind of genetic inheritance.

Experiments on mice at the Emory School of Medicine in Atlanta, Georgia, have demonstrated that they can be trained to associate a particular kind of smell to a fearful memory and that this fear can be passed down.

The findings raise questions over whether a similar kind of inheritance occurs in humans, for example whether men exposed to the trauma of a foreign war zone can pass on this fearful behavioural experience in their sperm to their children and grandchildren conceived at home.
