Starr and McMillan’s HUMAN BIOLOGY, 8e, International 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, students then learn the basic concepts which help them think critically about these issues. In addition, each chapter’s "How Would You Vote?" question invites students 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. Lastly, carefully integrated instructor and student media helps with lecture prep, delivering course content and monitoring student’s progress through the content
