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:

Identify and describe the properties of life
Describe the levels of organization among living things
Recognize and interpret a phylogenetic tree
List examples of different subdisciplines in biology

Examines the dynamic interrelations among physical and behavioral traits of humans, environment, and culture to provide an integrated framework for studying human biological evolution and modern diversity. Topics include issues in morphological evolution and adaptation; fossil and cultural evidence for human evolution from earliest times through the Pleistocene; evolution of tool use and social behavior; modern human variation and concepts of race. Includes study of stone artifacts and fossil specimens.

Survey of the important aspects of modern sediments and ancient sedimentary rocks. Emphasis is on fundamental materials, features, and processes. Textures of siliciclastic sediments and sedimentary rocks: particle size, particle shape, and particle packing. Mechanics of sediment transport. Survey of siliciclastic sedimentary rocks: sandstones, conglomerates, and shales. Carbonate sediments and sedimentary rocks; cherts; evaporites. Siliciclastic and carbonate diagenesis. Paleontology, with special reference to fossils in sedimentary rocks. Modern and ancient depositional environments. Stratigraphy. Sedimentary basins. Fossil fuels: coal, petroleum.
