This document is from the Rapid Learning Center and provides a tutorial on evolution concepts and mechanisms for the AP Biology exam. It begins with learning objectives around understanding evolution, applying it, and analyzing Darwin's theory of evolution. It then covers key topics like descent with modification, natural selection, genetic variation, Darwin's hypothesis, and evidence that supports evolution from fossils, taxonomy, embryology and genetics. Modern extensions to evolutionary theory are also discussed, like punctuated equilibrium and the role of the environment. The tutorial concludes by summarizing Darwin's theory of descent with modification and natural selection as the major forces of evolution.
