African societies were matrilineal.
Since the beginning of time, African societies have been matrilineal. People traced their ancestry through their mothers and inherited property from them rather than their fathers. A new husband would join his wife's family. Women played significant (often dominant) roles in trade; they were also primary farmers, managed child care, and prepared food. In comparison to European societies, Native American and African societies tended to be matrilineal.
Households with matrilineal members are less likely to benefit from cooperation. Children of matrilineal women, on the other hand, are healthier and more educated.
