From its original publication to this dramatically revitalized Eighth Edition, Life has always provided instructors with everything they need to show students how biology works, offering an engaging and coherent presentation of the fundamentals of biology by describing the landmark experiments that revealed them. This edition is the most extensive revision to date, from the addition of new coauthor David Hillis and the complete updating of the ecology section, to the dynamic redesigned look and next-generation student and instructor media tools.
