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.

By the end of this section, you will be able to do the following:

Define species and describe how scientists identify species as different
Describe genetic variables that lead to speciation
Identify prezygotic and postzygotic reproductive barriers
Explain allopatric and sympatric speciation
Describe adaptive radiation

We will explore the notion of creativity as it pertains to new ways of engaging familiar topics and carving out frameworks for exploring uncharted territory. We will actively read and respond to works of creative nonfiction to enrich our understanding of structure, style, and language. Assigned readings will demonstrate how creative nonfiction can encompass a variety of forms (think: reportage, braided essay, erasure, visual essay) and draw from both research and experience to offer a unique perspective and elicit an emotional response. We will develop our own creative nonfiction toolbox through a series of reflections, creative exercise, and projects. We will provide our classmates with thoughtful feedback to ensure collective growth.
