  1. What was the name of the ship Darwin sailed?
    HMS Beagle
  2. Why was Darwin's work so important?
    It revealed that the living world changes continuously.
  3. Darwin focused on what 3 patterns of diversity?
    • 1.  Species vary globally
    • 2.  Species vary locally
    • 3.  Species vary over time
  4. Vocab:

    History of life as documented in fossils
    Fossil Record
  5. What was Darwin's observation about "species vary globally?"
    He noticed that different, yet ecologically similar, species inhabited separated, but ecologically similar habitats around the world.

  13. Vocab:

    The flow of alleles due to migration
    Gene Flow
  14. Vocab:

    The change in genetic material of a cell
  15. Vocab: 

    When gametes from 2 parents join therefore increasing genetic variation
    Gene Shuffling (recombination)
  16. What are the 4 parts of Natural Selection
    1.  Variation exists

    2.  Organisms compete

    3.  More offspring are produced then can survive.

    4.  Environments selects organisms with beneficial traits.
  17. Vocab:

    A mechanism that prevents different populations from interbreeding
    Reproductive Isolation
  18. Vocab:

    Barriers that prevent members of the population from mating with each other.
    Geographic Isolation
  19. Vocab:

    When a population has a specific way to find mates
    Behavioral Isolation
  20. Vocab:

    When an organism is active at different times of the day or have different seasons for breeding
    Temporal Isolation
  21. Vocab:

    Seasonal behavior resulting in movement from one environment to another
  22. Vocab:

    A random change in allele frequency (it decreases variation)
    Genetic Drift
  23. Vocab: 

    A form of natural selection in which individuals at one end of the curve have a higher fitness then at the other end.
    Directional Selection
  24. Vocab:

    A form of selection in which individuals near the center of the curve have a higher fitness then at the ends
    Stabilizing Selection
  25. Vocab:

    Natural Selection in which individuals at both ends of the curve have a higher fitness then the ones in the middle.

  28. Vocab:

    The evolution of 2 species based on their interaction with one another.
  29. Vocab:
