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.

An introduction to diverse musical traditions of the world. Music from a wide range of geographical areas are studied in terms of structure, performance practice, social use, aesthetics, and cross-cultural contact. Includes hands-on music making, live demonstrations by guest artists, and ethnographic research projects. This course explores the ways that music is both shaped by and gives shape to the cultural settings in which it is performed, through studying selected musical traditions from around the world. Specific case studies will be examined closely through listening, analysis, and hands-on instruction. The syllabus centers around weekly listening assignments and readings from a textbook with CDs, supplemented by hands-on workshops, lecture/demonstrations and concerts by master musicians from around the world.
