The second edition of this evolutionary biology textbook for undergraduate students has been expanded to include new sections on the evolution of sex and sexual selection, cooperation and conflict among species, new developments in human genetic variation and the evolution of parasites and pathogens. Futuyma (ecology and evolution, State U. of New York at Stony Brook) also covers such fundamental topics as speciation, group selection, major discoveries in the fossil record and diversity. A companion website provides data analysis and simulation exercises, online quizzes, flashcards and key terms, chapter summaries and outlines and a glossary.
