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.
