How Humans Evolved

Using the broad perspective of behavioral ecology--how human behavior has been influenced by the evolutionary process--the authors offer a balanced discussion, drawing on updated coverage of the human fossil record. The well-structured pedagogical framework of the text, with its emphasis on overarching ideas, makes the material accessible to introductory students.
