"Should you make room in your financial and time budgets to buy and read yet another volume of expanded, revised conference papers? In the case of Sex and Gender Hierarchies, the answer is a resounding yes if your research or teaching interests include sex differences and gender relationships in primates. This collection of 17 chapters drawn from the four subfields of anthropology, accomplishes what many such volumes only promise to do. It is an impressive analysis of a specific issue--systematic relationships of inequality based on sex and gender--from the perspectives of first-rate biological and social/cultural anthropologists, archaeologists, and linguists."
