The “modern studies” of a system named for these people was founded by the activist Heide Göttner-Abendroth. Friedrich Engels theorized that “primitive communism” first arose in social structures (-5[1])named for these people, citing Lewis Morgan’s Ancient Society. The Lithuanian scholar Marija Gimbutas claimed that a social structure named for these people dominated in “Old Europe” until the invasion of the Kurgan culture. The (10[1])Moynihan Report controversially posited the “Black” form of a social structure (0[1])named for these people as a downstream effect of over-incarceration. (10[1])These people dominate in (10[1])“focal” structures (-5[1])named for them common (10[1])in the Caribbean, which is related to a system where kinship is “lineal” in them, such as among the Iroquois. For 10 points, name these people who name a social structure contrasted with patriarchy. ■END■ (10[1])
