The living world today contains all kinds of creatures that do unexpected things-- we have come to expect that there were complex and unusual ways of life in the past, and that evolution took some unexpected turns at times. Entertainingly written for students, History of Life 4th Edition takes you to the edge of current knowledge.

This text is aimed at students and anyone interested in the history of life on our planet. It explores the "whys" of events that occurred and, in this newest edition, it takes a closer look at the evolution of the physical earth and the strong interactions between organisms and environment. The book's coverage includes geography, climate, atmosphere, ocean, and land (a changing stage) while following the interplay between organisms. Also new to this edition is a dedicated website which explores additional environmental factors and supplemental topics, and provides interactive exercises, a detailed glossary, key links and all art in downloadable form. The art is also available to instructors on CD-ROM in PowerPoint and Jpeg formats.
