Daughters breastfed longer, and women accumulated greater wealth in ancient California matriarchal society
University of UtahWomen buried at the ancestral Ohlone site of Kalawwasa Rummeytak in the San Francisco Bay Area in California were breastfed longer and accumulated greater wealth than the men. Isotopic analysis indicates that after marriage, men lived with their wives’ families and women tended to remain in their birth community. This study is the first of its kind to uncover wealth-driven patterns in maternal investment among ancient populations.
