UC Museum of Paleontology Grade level:
9-12 Time:
Two to four class periods. Concepts: - Biological evolution accounts for diversity over long periods of time.
- An organism’s features reflect its evolutionary history.
- Similarities among existing organisms provide evidence for evolution.
- Anatomical similarities of living things reflect common ancestry.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientists use anatomical evidence to infer the relatedness of taxa.
- 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.
