Multiple fathers prevalent in Amazonian cultures
Date:11/10/2010

aphies for 52 societies do not mention conception beliefs.

Walker's team has several hypotheses on the benefits of multiple paternity. Women believed that by having multiple sexual partners they gained the benefit of larger gene pools for their children. He says women benefited from the system because secondary fathers gave gifts and helped support the child, which has been shown to increase child survival rates. In addition, brutal warfare was common in ancient Amazonia, and should the mother become a widow, her child would still have a father figure.

Men benefitted from the multiple paternity system because they were able to formalize alliances with other men by sharing wives. Walker hypothesizes that multiple paternity also strengthened family bonds, as brothers often shared wives in some cultures.

Walker collaborated with Mark Flinn, professor in the MU Department of Anthropology, and Kim Hill, professor in Arizona State University's School of Human Evolution and Social Change.
