Biological anthropology, also known as physical anthropology, is concerned with the biological and behavioral aspects of human beings, their related non-human primates and their extinct hominin ancestors. It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings. This textbook explores evolutionary theory, including the core concepts of basic genetics and the modern synthesis of evolution. Students will examine, critically evaluate and explain scientific claims about the origins of humankind and modern human variation as well as biocultural evolution. Students will develop critical thinking and communication skills through the application of essential anthropological approaches, theories, and methods.
