"Life" integrates scholarship, an engaging narrative style, effective pedagogy, and art-work into a cohesive presentation of biological data and ideas that should interest students. The third edition features a new co-author - H.Craig Heller and new information - from new molecular techniques in biotechnology, immunology, and systematics. New chapters have been added on conservation biology and on recombinant DNA. Organized differently, the text addresses evolution before diversity and physiology. The artwork blends scientific precision and visual impact.
