  1. 15-3 Notes: EVOLUTION IN ACTION pp. 308-311

  2. Evolution defined… • Evolution of a population is due to environment and the interactionof other species

  3. Artificial Selection • humans breed for specific traits causing differences in species (i.e. dog breeding)

  4. Types of Evolution • Convergent evolution: Organisms with very different ancestors become more alike due to a common environment • (i.e fish and whales)- compare analogous structures

  5. Ex: whale and fish, bird and insect

  6. Types of Evolution • Divergent evolution: populations become more and more dissimilar to adapt to the environment • -compare homologous structures

  7. Adaptive Radiation: Population undergoes divergent evolution until it fills all areas of the environment

  8. EX: Rough-skinned newt and garter snake • Newt evolved to produce neurotoxins then the snake evolved resistance to this toxin through genetic mutations. Birds and flowers, Humans and bacteria are other examples

  9. coevolution • When two species each evolve in response to each other over a long period of time.  • This leads to a close relationship

  10. Classwork • “Types of Evolution Tree Map” • Vocabulary 4-squares • Convergent evolution • Divergent evolution • Artificial selection • Coevolution
