  1. 4. an organism's ability to survive and reproduce in its environment, effectively passing on its genes to the next generation.
  2. 6. an evolutionary adaptation where one organism, the mimic, evolves to resemble another organism, the model, or even an inanimate object, for a survival advantage
  3. 10. the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
  4. 12. the seasonal or long-range movement of animals from one habitat to another.
  5. 13. a change or the process of change by which an organism or species becomes better suited to its environment.
  6. 14. Artificial selection is the process where humans actively choose which individuals within a population (plants or animals) will reproduce, based on desired traits, leading to the selective breeding of those traits over time.
  7. 15. a physical characteristic of an organism that helps it survive and reproduce in its environment

  1. 1. heritable change in an organism's genetic material (DNA or RNA) that provides the raw material for evolutionary change.
  2. 2. the internal adjustments an organism makes to its body's functions in order to better cope with changes in its environment
  3. 3. random fluctuations in the frequency of different gene variants (alleles) within a population over time.
  4. 5. the adaptation of an organism's color, pattern, or shape to blend in with its surroundings, making it difficult to detect or recognize by predators or prey.
  5. 7. the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
  6. 8. the concept that within a population, some individuals reproduce more successfully than others due to variations in their traits.
  7. 9. body parts in different species that serve similar functions but have different origins and evolutionary histories.
  8. 11. a body part that has lost much or all of its original function through evolution.
