For non-majors introductory biology courses covering core areas such as cell biology, genetics, evolution, plant and animal anatomy and physiology, and ecology. A briefer version of the highly successful Biology: Life on Earth, 5/e (1999), Life on Earth, 2/e was developed in collaboration with a team of biology educators to meet the needs of non-majors. It is designed to engage students in biological exploration, to ensure currency and accessibility, and to provide a flexible, integrated teaching/learning package.
