Presenting core concepts in a relevant context, Starr and McMillan's Human Biology, 9th edition, International Edition gives students a clear understanding of how the human body works and helps them make well-informed choices as consumers and voters. Each chapter opens with a human biology-related issue currently in the news that highlights the relevance of biology and motivates the study of the topic. Students then learn the 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. 'How Would You Vote,' 'Future Focus,' and 'Explore on Your Own' sections demonstrate the impact and personal relevance of the content on their lives. Lastly, carefully integrated instructor and student digital tools help with preparing lectures, delivering course content, and monitoring student's progress.
