Overview:
In this web-based module students are introduced to cladistics, which organizes living things by common ancestry and evolutionary relationships.

Author/Source:
UC Museum of Paleontology

Grade level:
9-12

Time:
Two to four class periods.

Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Biological evolution accounts for diversity over long periods of time. (LS4.A, LS4.D)

  • An organism's features reflect its evolutionary history.

  • 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 test their ideas using multiple lines of evidence. (P6, NOS2)

  • Scientists use anatomical evidence 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.

  • Classification is based on evolutionary relationships.

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