  • Evidence of Evolution

  • An organism's features reflect its evolutionary history.

  • All life forms share fundamental similarities. (LS4.A)

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

  • Mechanisms of Evolution

  • Evolution results from natural selection acting upon variation within a population. (LS4.B)

  • Studying Evolution

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

  • Scientists use artificial selection as a model to learn about natural selection. (P2)

  • There is variation within a population. (LS3.B)
