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.

  • 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.

  • Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.

  • Evolutionary trees can be used to make inferences and predictions.
