Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Welcome! This is the site for the lecture component of Bio1100 D854. This site contains the lecture syllabus and links to the free OER (open educational resource) textbooks that we will be using.

This OER is intended as a textbook for a one semester introductory course in Human Anatomy and Physiology for non-science majors. It covers the major topics typically covered in A&P, but in a simplified, easier to understand manner. This textbook aims to educate students interested in lower-level health careers and non-science majors without the intimidating detail found in current textbooks. Text and images were created to be more accessible for these student populations.
