1. The Fossil Record

2. Evidence of Evolution
Fossil Record provides evidence that living things have evolved
Fossils show the history of life on earth and how different groups of organisms have changed over time

3. Relative vs. Absolute Dating

4. Relative Dating
Performed by estimating fossil age compared with that of other fossils
The deeper it is, the older it is.
Drawbacks – provides no info about age in years

5. Absolute Dating Can determine the absolute age in years
Is performed by radioactive dating – based on the amount of remaining radioactive isotopes
Drawbacks - part of the fossil is destroyed during the test
