My father was raised by his dad and mom. I was raised by my dad and mom. My grandfather's were raised by their fathers and mothers. So that's three generations of men not raised only by their mothers. Civilization is built upon the inclusion of men in childrearing, so ultimately all civilizations include men raised by both men and women (at least the successful ones).
