Essential Biology
The authors use evolution as the thematic thread to tie all twenty chapters into a cohesive exploration of life. In Essential Biology, the clarity of writing complements an exciting new art program. The art works hand-in-hand with text discussions to help students visualize difficult concepts.  Essential Biology is a brief biology book that brings the authors' extraordinary reputation for biological accuracy and teaching innovation to bear upon four core biological topics: cells, genetics, evolution, and ecology.
