2. The Fossil Record

3. Fossils in Sedimentary Rock Water carries small rock particles to lakes and seas. Dead organisms are buried by layers of sediment. The preserved remains may later be discovered and studied. 1 2 3

4. What Can Fossils Reveal?

5. Relative Dating

6. Radiometric Dating

7. Geologic Time Scale

8. Life on a Changing Planet End of the Permian PeriodTriassic Period End of the Cretaceous Period Present Day

9. Macroevolution Dinosauria Ornithischia Saurischia Aves CrocodilesOrnithischiansSauropods T. rex Archaeopteryx Modern birds

10. Patterns of Extinction

11. Rate of Evolution Why did Darwin think evolution was a gradual process? Why are horseshoe crabs an example of a species in a state of equilibrium? How is punctuated equilibrium different from gradualism? When might rapid evolution take place?

13. Convergent Evolution

14. Coevolution How might the relationship in this photo indicate coevolution?

15. Overview of Patterns and Processes 1.Identify the patterns that describe the sequential nature of groups in the fossil record. 2.Explain what the fossil record shows about periods of stasis and rapid change. 3.Name two important patterns in macroevolution. 4.Explain the evolutionary characteristics of coevolving organisms.
