Perhaps it was only during the dawn of the human race that women 11 stood equal with men. At the beginning, I think both sexes shared equal responsibility for the 12 of the race.

Men who are physically stronger 19 on such " natural" roles as warriors, and in most cases men became chiefs, commanders, and kings. In the 20 of history, as matriarchal systems became minorities in many cultures, the roles of men and women in many societies became increasingly gender-oriented and differentiated.
