This book demonstrates the centrality of sex, gender, and sexuality to theories of human behaviors and practices. Moves beyond other "lesbian and gay studies" readers by presenting a broader view of the significance of studying same-sex cultures and sexualities across cultures. Offers readings from all four subfields of anthropology: cultural, biological, linguistic, and archaeological (along with historical and applied anthropology). Includes discussion of biotechnology and bioethics, health and illness, language, ethnicity, identity, politics, post-colonialism, kinship, development, and policymaking.
