Starr and McMillan's HUMAN BIOLOGY, 8th Edition presents the core areas of human biology with an emphasis on not only the internal world, but how we impact our external world. Highlighting biology's relevance, each chapter opens with an "Impacts, Issues" reading on a human biology-related issue currently in the news. Within the chapter, users then learn the basic concepts which help them think critically about these issues. In addition, each chapter's "How Would You Vote?" question invites users to explore current issues and deepen their understanding through online exercises. By the end of the chapter, learners are asked to "Explore on Your Own", and participate in activities showing the impact of the content on their lives.
