Hailed for its clear writing, scientific accuracy, and real-world examples, Essential Biology is a brief non-majors biology text that focuses on the core concepts readers need to make scientifically informed decisions throughout their lives. The book covers four major topics–cells, genetics, evolution/diversity, and ecology–and uses evolution as an overarching theme to tie all 20 chapters together. Human applications and the most up-to-date information on important issues show readers how biology relates to their own lives. New Process of Science sections within the text draw readers into the material and provide real-world examples of how the scientific method is applied.
