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:

Explain how electromagnetic waves differ from sound waves
Trace the path of light through the eye to the point of the optic nerve
Explain tonic activity as it is manifested in photoreceptors in the retina

Culture, Embodiment, and the Senses will provide an historical and cross-cultural analysis of the politics of sensory experience. The subject will address western philosophical debates about mind, brain, emotion, and the body and the historical value placed upon sight, reason, and rationality, versus smell, taste, and touch as acceptable modes of knowing and knowledge production. We will assess cultural traditions that challenge scientific interpretations of experience arising from western philosophical and physiological models. The class will examine how sensory experience lies beyond the realm of individual physiological or psychological responses and occurs within a culturally elaborated field of social relations. Finally, we will debate how discourse about the senses is a product of particular modes of knowledge production that are themselves contested fields of power relations.

"This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate, or are they acquired by experience? (And what does it even mean to call a concept 'innate'?) Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course will include guest lectures by Professors."
