内容説明

Bridging anthropology courses in human evolution and more biologically oriented courses in human anatomy, this text is intended for upper level undergraduate/graduate courses typically called human evolutionary anatomy. It presents important concepts and factual descriptions of human anatomy at a level that does not assume specific prior knowledge and applies this knowledge in functional and adaptive perspectives. Humans are presented as vertebrates, mammals, and primates; the specializations at each level of texonomic distinction are presented for each body system as applicable.
