Is the theory of evolution adequate? This textbook introduces students to the subject of biological evolution. Evolution is the change in the inherited traits of a population of organisms through successive generations through biological means. It begins with a thorough discussion of Darwin's theory of evolution and his ideas for how new species develop over time. The author follows this with a comprehensive review of the alternative theories of mechanisms that result in a new species.
