"A unique and very valuable textbook that is long overdue in the field. It is the first introductory book that I know of that starts from a biosocial perspective. Hopcroft's book should make it easy for teachers who have a typical sociology background to incorporate an evolutionary perspective in their teaching."
         -- Franois Nielson, University of North Carolina-Chapel Hill

"This textbook shows how sociology encompasses all fundamental and major aspects of human life and behavior. No other text does this. Hopcroft's text adds tremendous depth to the sociological perspective. Moreover the author writes in such a way that undergraduates - even those who normally find reading to be a chore - will quickly grasp the central ideas of the book and will develop the appropriate level of understanding the complex connections between sociology and the life sciences."
         -- Jeff Davis, California State University-Long Beach

"By using an interdisciplinary approach, Hopcroft brings sociology into the 21st century. Introductory sociology students in a community college setting will especially benefit from this text as it easily and neatly compliments other core areas of study in the natural sciences."
