Building upon Scott Freeman's unique narrative style that incorporates the Socratic approach and draws readers into thinking like a biologist, the Fourth Edition has been carefully refined to motivate and support a broader range of learners as they are introduced to new concepts and encouraged to develop and practice new skills. Each page of the book is designed in the spirit of active learning and instructional reinforcement, equipping novice learners with tools that help them advance in the course-from recognizing essential information in highlighted sections to demonstrating and applying their understanding of concepts in practice exercises that gradually build in difficulty. The new edition makes it easier than ever for readers to locate information and learn concepts, with: Remarkable "Big Picture" concept maps that help students synthesize information across chapters A complete answer key in the back of the book More concise discussions on selected topics with a clearer sub-heading structure for easier navigation A finely-tuned art program with improved clarity and contrast among biology structures and an improved orientation for phylogenetic trees An expanded BioSkills appendix at the end of the book helps readers learn and practice foundational skills, which range from interpreting graphs to how to read a phylogenetic tree to common Latin and Greek word roots, and reading chemical structures. New to Freeman's MasteringBiology(TM) online tutorial and assessment system are ten classic experiment tutorials and automatically-graded assignment options that are adapted directly from content and exercises in the book.
