GENERAL BIOLOGY is an introductory level college biology textbook that provides students with an understandable and engaging encounter with the fundamentals of biology. Written for a two-semester undergraduate course of biology majors and presented as a bound set of two distinct volumes, this reader-friendly textbook(s) is concept driven vs. terminology driven. That is, the book(s) are based on the underlying concepts and principles of biology rather than the strict memorization of biological terms and terminology. Written in a student-centered and conversational style, this educational research-based book(s) connects students to all aspects of biology from the molecular to the biosphere. End-of-chapter questions challenge students to think critically and creatively while incorporating science process skills and biological principles.
