Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.

  • During the course of evolution, only a small percentage of species have survived until today.

  • The fossil record provides evidence for evolution.

  • There are similarities and differences among fossils and living organisms.

  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
