Goldsmith and Zimmerman's interdisciplinary textbook is just the thing for introducing students to the significance of evolution for our understanding of human nature. "Using evolution as the unifying theme, this book traces the connections between levels of complexity, showing how both the study of other organisms and a variety of perspectives from biology, psychology, and anthropology provide complementary insights", Goldsmith and Zimmerman explain. Steven Pinker describes their book as "[a]n excellent introduction to a body of knowledge and concepts that should be mastered by every educated person."
