Biological Anthropology, 3/e is written to appeal to a wide range of students. It continues to build upon the strength and success of its first and second editions by integrating the foundations of the field with the most current innovations happening today.

Over the past 40 years, biological anthropology has rapidly evolved from the study of physical anthropology into biological anthropology. Biological anthropology is now an integrative combination of information from the fossil record and the human skeleton, genetics of individuals and of populations, our primate relatives, human adaptation, and human behavior. The third edition of Biological Anthropology combines the most up-to-date, comprehensive coverage of the foundations of the field with modern innovations and discoveries.
