As in previous editions of this textbook, the 5th edition shows biology not as a collection of facts, but as a dynamic discipline. The student's understanding of biological processes is developed through pedagogy, using narrative, experimental contexts and art within the scholarship. This edition contains new artwork incorporating biological storyboards; new chapters on molecular evolution, higher brain functions and animal embryology; and genetics coverage expanded by new co-author and genetics specialist, David Sadava. The student CD-ROM - Life: the science of biology 5.0: Molecules, Cells, and Genes has more than 1500 topics and has been class-tested. It includes self-quizzes, an audio pronunciation guide for more than 300 terms, and 40 minicourses expanding on the book's coverage of topics from mitosis to genetics information.
