1. Patterns of Evolution

2. Key Terms Natural Selection Artificial Selection Convergent evolution Divergent evolution Co-evolution

3. Artificial selection is intentional breeding for certain traits or combination of traits. A.True B.False

4. The process of natural selection can happen to any species. A.True B.False

5. Natural selection operates only on populations, not individuals, over generations. A.True B.False C. All of the above

6. Convergent evolution Similar traits develop in organisms who do NOT have a close ancestor Traits are due to adaptations to similar environments

7. Divergent Evolution A pattern in which highly distinct (very different) species were once similar to an ancestral species Ancestor = organism from the past

8. What is an example of divergent evolution? A.Black squirrels B.Homo Sapiens C.Finches on Galapagos Islands D.A Liger

9. Divergent evolution is the same as convergent evolution. A.True B. False

10. What is the process in which species that are NOT closely related to each other independently evolve SIMILAR kinds of traits? A.Natural Selection B.Convergent Evolution C.Divergent Evolution D.Co-evolution

11. Co-evolution A process in which the changes in the genes of one population bring about changes in a different population The organisms involved share a symbiotic relationship

12. What is NOT one of the three types of species that offer the most fertile ground for co-evolution? A.Predators B.Prey C.Scavengers D.Parasites
