  8. What are the 5 patterns of MacroEvolution?
    • 1.Mass Extinctions
    • 2.Adaptive radiation
    • 3.Convergent evolution
    • 4.Coevolution
    • 5.Punctuated equibrium and Gradualism
  9. What is mass extinction?
    When groups of species were wiped of the face of the earth. This changed ecosystems and food webs. New species also evolved afterwards.
