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.
