- Disciplinary Core Ideas
- LS4.A Fossils provide evidence about the types of organisms that lived long ago and also about the nature of their environments.
- NRC Framework
- LS4.A Evidence for common ancestry can be found in the fossil record, from comparative anatomy and embryology, and from the similarities of cellular processes and structures, and from comparisons of DNA sequences between species.
