This is a great introductory activity for a unit on phylogenetic.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- 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)
- Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
- Not all similar traits are homologous; some are the result of convergent evolution.
