  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. • True • False

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

  5. Natural selection operates only on populations, not individuals, over generations. • True • 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? • Black squirrels • Homo Sapiens • Finches on Galapagos Islands • A Liger

  9. Divergent evolution is the same as convergent evolution. • True • False

  10. What is the process in which species that are NOT closely related to each other independently evolve SIMILAR kinds of traits? • Natural Selection • Convergent Evolution • Divergent Evolution • 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? • Predators • Prey • Scavengers • Parasites
