Biology of Dads

Child psychologist Laverne Antrobus goes on a quest to discover why dads are so important. Through a series of extraordinary experiments she discovers how radical changes in a man's hormones during his partner's pregnancy actually serve to boost his nurturing instincts. Laverne's final investigation is perhaps most intriguing of all: can a father's relationship with his daughter really influence when she reaches puberty and who she eventually marries?
