  1. 5. Form of natural selection in which individuals at the upper and lower ends of a distribution curve have higher fitness than individuals near the middle, and subsequently leads to speciation and a split in the population.
  2. 6. Selective breeding of plants and animals to promote the occurrence of desirable traits in offspring.
  3. 11. Preserved remains of ancient organisms.
  4. 12. Form of reproductive isolation in which two populations are separated by geographic barriers such as rivers, mountains, or bodies of water, leading to the formation of two separate subspecies.
  5. 13. Form of reproductive isolation in which two populations develop differences in courtship rituals or other behaviors that prevent them from breeding.
  6. 14. The change in allele frequency/physical traits over time.
  7. 16. Form of natural selection in which individuals near the center of a distribution curve have higher fitness than individuals at either end of the curve.
  8. 18. How well an organism can survive and reproduce in its environment.
  9. 19. All of the genes/alleles that are available in a population of organisms at any given time.
Down
  1. 1. Process by which organisms that are most suited to their environment survive and reproduce most successfully.
  2. 2. Form of natural selection in which individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve, and subsequently shifts the curve.
  3. 3. Separation of a species or population so that they no longer interbreed and evolve into separate species.
  4. 4. Form of reproductive isolation in which two or more species reproduce at different times.
  5. 7. Formation of new species.
  6. 8. Structure that is inherited from ancestors but which has lost much or all of its original function.
  7. 9. Structures that are similar in different species of common ancestors. (Similar structure, different function).
  8. 10. Body parts that share common function, but not an evolutionary history. (Similar function, different structure).
  9. 15. The selection of mates based on heritable traits.
  10. 17. A heritable trait that increases an organism's ability to survive and reproduce in a particular environment.
