The Wikipedia article mentions birth stress as a possible cause. My son had a difficult delivery and possible mild birth asphyxia. Nobody else in my family that I know of is ambidextrous. His highly gifted half-brother is left handed and his very bright, high school football star cousin is left handed, but everyone else in the family is right handed.
