- Evidence of Evolution
- An organism's features reflect its evolutionary history.
- All life forms share fundamental similarities. (LS4.A)
- Anatomical similarities of living things reflect common ancestry. (LS4.A)
- Mechanisms of Evolution
- Evolution results from natural selection acting upon variation within a population. (LS4.B)
- Studying Evolution
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Scientists use artificial selection as a model to learn about natural selection. (P2)
- There is variation within a population. (LS3.B)
