  1. Evolution through natural selection is based on the idea that the most ________________ characteristics of a species are favored.
    • Evolution through natural selection is based on the idea that the most DESIRABLE 
    • characteristics of a species are favored.
  2. DEFINE MIGRATION
    WHEN INDIVIDUALS MOVE FROM ONE POPULATION TO ANOTHER.
  3. DEFINE MUTATION
    • A change in the DNA.
    • Mutations are random and can be beneficial, neutral, or harmful for the organism. Mutations do not "try" to supply what the organism "needs.“
  4. WHAT'S THE SONG FROM CLASS?
    RANDOM MUTATION AND RECOMBINATION CREATE VARIATION!
  5. NAME SOME SOURCES OF GENETIC VARIATION
    • MIGRATION
    • MUTATION
    • RECOMBINATION (REPRODUCTION)
    • GENETIC DRIFT
    •  -BOTTLENECK
    •  -FOUNDERS' EFFECT
  6. A small group of humans leaves Earth and colonizes a new planet.  After many generations, the population on this planet has an unusually high frequency for the incidence of retinitis pigmentosa, relative to Earth's population. This is most likely due to what?
    FOUNDERS' EFFECT
  7. Nature cannot sustain unlimited growth of populations. It controls this by competition, otherwise known as  _________ _________.
    Nature cannot sustain unlimited growth of populations. It controls this by competition, otherwise known as SELECTIVE PRESSURES.
  8. NAME THE TYPES OF SELECTIVE PRESSURES AND AN EXAMPLE OF EACH ONE.

  9. Mutation, Migration and Genetic drift all bring __________ genetic variety to the gene pool of a population.
    Mutation, Migration and Genetic drift all bring RANDOM genetic variety to the gene pool of a population.
  10. _________ _________: The differential survival and reproduction of individuals due to differences in phenotype.
    NATURAL SELECTION: The differential survival and reproduction of individuals due to differences in phenotype.
  11. NATURAL SELECTION IS WHAT TYPE OF CHANGE?
    • It is an ADOPTIVE change.
    • Evolution through natural selection results in specific adaptations that enable a species to become better suited to survive and reproduce in its specific niche.
  12. NAME THE THREE WAYS THE TERM "NICHE" IS USED.
    • (1) The specific area where an organism inhabits.
    • (2) The role or function of an organism or species in an ecosystem.
    • (3) The interrelationship of a species with all the biotic and abiotic factors affecting it.
  13. Natural section is __________ way of __________ what survives and what does not.
    Natural section is NATURE’S way of SELECTING what survives and what does not.
  14. If you have
    1.____________,
    2.____________, AND
    3.____________,
    you will have evolution by natural selection as an outcome.
    • If you have
    • 1. variation,
    • 2. differential reproduction, and
    • 3. heredity,
    • you will have evolution by natural selection as an outcome.

    THINK ABOUT THE GREEN AND BROWN BEETLE FROM OUR CLASS DISCUSSION.
  15. Adaptation:  The __________ characteristics of a species that develops over time in response to an environmental factor, enabling the species to survive.
    Adaptation:  The INHERITED characteristics of a species that develops over time in response to an environmental factor, enabling the species to survive.

  18. Which of the following organisms is most successful in evolutionary terms?

    A. the one that has the largest territory

    B. the one that leaves behind the greatest number of offspring
    B. the one that leaves behind the greatest number of offspring. 

    THINK FITNESS! 
  19. IN THE POCKET MOUSE ACTIVITY, WHAT HAPPENED THAT CREATED THE BLACK MOUSE POPULATION?
    A MUTATION
  20. HOW MANY TITLES ARE ON A BAR GRAPH?
    • THREE.
    • GRAPH TITLE, X AXIS, AND Y AXIS.
