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. (LS4.A)

  • Features sometimes acquire new functions through natural selection.

  • Similarities among existing organisms provide evidence for evolution. (LS4.A)

  • Scientists can test ideas about events and processes long past, very distant, and not directly observable.

  • Science is a human endeavor. (NOS7)

  • Our knowledge of the evolution of living things is always being refined as we gather more evidence.

  • Scientists use anatomical evidence to infer the relatedness of taxa. (LS4.A)

  • Classification is based on evolutionary relationships.

  • Evolutionary trees (i.e., phylogenies or cladograms) are built from multiple lines of evidence.
