Clear, engaging, and visually compelling, Starr and McMillan's HUMAN BIOLOGY, 11e teaches students the core concepts of human biology and prepares them to make well-informed decisions in their lives. Each chapter opens with an interesting application that highlights the relevance of biology and motivates the study of the topic. Students then learn basic concepts which help them think critically about these issues. Useful pedagogy, such as section-ending "Take-Home Messages" and a running glossary, ensure students understand key concepts. New "Focus on Human Impact" boxes and chapter-ending "Your Future" and "Explore on Your Own" sections demonstrate to students the impact and personal relevance of the content on their lives.
