Book excerpt: For sophomore- to junior-level courses in Evolution, with an Introductory Biology prerequisite.This text introduces biology majors to the basic concepts of the fields comprising Darwinian biology: population genetics, population ecology, community ecology, macroevolution, physiological ecology, systematics, and functional morphology. The general theme is the interconnectedness of organism, environment, and evolution. Just as biochemistry and molecular biology provide the foundation for our understanding of the cell, evolutionary biology and ecology are used to construct a foundation for understanding the organism. Using evocative language and an eye-catching magazine format, the authors aim to prepare undergraduates for more advanced specialist courses in Darwinian biology as they pursue their degrees.
