Jacques Lizot (“ZHAHCK LEE-zoe”) was accused of trading sex for guns with members of this ethnic group in a controversy chronicled by the film The Secrets of the Tribe. Ettore Biocca (“eh-TORE-ay bee-AHK-kah”) recorded the experiences among this ethnic group of Helena Valero, who was kidnapped by them. These people build large communal homes with a central hole called shabono and use the hallucinogen (15[1])ebene. Patrick Tierney criticized anthropologists for giving bad measles vaccines to this group, the subjects of (*) “The Ax Fight,” (10[1])in (10[1])Darkness in El Dorado. This group was the primary case study in a book arguing that people fought constantly before Western contact because more violent men passed down their genes. For 10 points, name this ethnic group called “The Fierce People” (10[1])in a Napoleon Chagnon (“SHAG-nahn”) book set in the Amazon. (0[5])■END■
