LIFE BY DESIGN is a one-semester introduction to biology for non-major undergraduate students and advanced secondary level students. It departs from a tedious encyclopedic approach in favor of stating and exemplifying 12 basic principles that describe all living things. It is integrative of science and other disciplines, giving science a context in the non-major's thinking. The text also invites the student to examine the origins of life forms from both a Darwinian and a design perspective and aids the reader in following the authors' analysis of these two perspectives.
