  1. Differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment
    Natural selection
  2. Accumulation of inherited characteristics that enhance an organism's ability to survive and reproduce
    Adaptation ie: disruptive camouflage
  3. Breeding for particular characteristics process of domestication; results in new species
    artificial selection
  4. Features in different species are similar because of common ancestry: ie; how all arms have the same general bone structure
    homology
  5. Adaptations in different species are similar only due to similar selective pressures
    analogy (convergent evolution)
  6. What was the reason for the marsupial distribution
    It was a result of the continental drift
  7. Serve little if any purpose; what remains of ancestral adaptations lost over generation
    vestigial structures
  8. Specimens of now extinct forms of life can reveal evidence about where a modern organism fits into the tree of life; consider transitional whale fossils
    transitional fossils
  9. The whale once had hind legs list its original form to what it is today..
    pakicetus(terrestrial), rhodocetus(predominantly aquatic), dorudon (fully aquatic), balaena(recent ancestor)
