Research suggests that our fathers' genetic material has a stronger effect on the development of our instinctual behaviors (eating and mating), while the higher-order cognitive abilities (language, socialization, etc.) are the result of a greater contribution from our mothers. So now you know who to blame, and for what. [Via]
