  • An organism's features reflect its evolutionary history.

  • The fossil record contains organisms with transitional features.

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

  • Anatomical similarities of living things reflect common ancestry. (LS4.A)

  • A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)

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

  • Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)

  • Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
