Presentation Transcript

  1. Evolution

  2. Adaptive Radiation

  3. Adaptive Radiation • The speciation and adaptation of an array of species • Species show different morphological and physiological traits

  4. Galapagos

  5. Darwin’s Finches • Darwin noticed varieties of finches on the Galapagos • Kept specimens, but didn’t record which islands they came from • Back in England, recognized they were closely related, but different species • Finches evolved from an ancestor that came from mainland S.America

  6. Darwin’s Finches

  7. Convergent and Divergent Evolution

  8. Convergent Divergent Pattern of evolution in which species that were once similar to an ancestral species diverge, or become more distinct • Pattern of evolution in which similar traits arise because different species have independently adapted to similar conditions

  9. Convergent

  10. Divergent

  11. Mass Extinctions

  12. Mass Extinctions • Large scale dying out of a large percentage of all living organisms in an area over a relatively short period of time • There have been 5 global mass extinctions

  13. The Big 5

  14. Co-evolution

  15. Coevolution • The change of a species triggered by the change of a related object
