by Robert Boyd and Joan B. Silk provides a comprehensive college-level introduction to the study of biological anthropology. Rather than simply providing a list of facts, encourages students to think critically about the process of human evolution by engaging students in theoretical discussions and debates and by asking them to wrestle with larger questions, such as how humans acquired language, why we age and eventually die, why only women nurse babies, and why human morphology differs across geographical regions. The text is also accompanied by an outstanding ancillary package for instructors.
