  • [History of life: Grades 6-8] Biological evolution accounts for diversity over long periods of time.
  • [History of life: Grades 6-8] Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.
  • [Evidence of evolution: Grades 6-8] An organism's features reflect its evolutionary history.
  • [Evidence of evolution: Grades 6-8] There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)
  • [Evidence of evolution: Grades 6-8] Anatomical similarities of living things reflect common ancestry. (LS4.A)
  • [Evidence of evolution: Grades 6-8] Not all similar traits are homologous; some are the result of convergent evolution.
  • [Mechanisms of evolution: Grades 6-8] Traits that are advantageous often persist in a population. (LS4.B, LS4.C)
  • [Studying evolution: Grades 6-8] Scientists use anatomical features to infer the relatedness of taxa. (LS4.A)
