  2. 4. theory that describes abrupt rapid speciation
  3. 7. came up with the same idea as Darwin 23 years later
  4. 10. the comparative study of complex metabolic molecules that many different organisms share
  5. 13. the pattern of evolution where one species' adaptation affects another (bats & saguaros)
  6. 16. structures that are the reduced forms of functional structures in other organisms
  7. 18. type of gene flow where individuals leave a population
  8. 21. effect where a population declines & rebounds with little genetic diversity
  9. 22. a measure of reproductive success
  10. 24. functionally similar features that evolve independently in similar environments
  11. 25. theorized that ~ Human Population growth could outgrow food production
  12. 27. the type of isolation that can cause speciation that includes rivers, mountains, oceans, and canyons
  13. 30. type of isolation that can cause speciation that includes bird songs & dances
  14. 31. pattern of evolution marked by a central common ancestor giving rise to many species (finches)
  15. 32. a type of isolation that can cause speciation that includes reproduction at different times of the year
  16. 33. comparative study of the similarities in embryonic development
  17. 35. type of natural selection where a population shifts selection towards higher fitness in one direction
  18. 38. the naturalist who published ideas about natural selection (last name)
  19. 40. Hutton & Lyell proposed theory
  20. 41. type of natural selection where the extremes are selected over the average
Down
  1. 1. type of selection based on attracting the other gender
  2. 3. selection is done by nature
  3. 5. type of natural selection where the average has higher fitness than the extremes in a population
  4. 6. traits are those that are more recently evolved and are not in ancestral forms
  5. 8. structures that are anatomically similar inherited from a common ancestor
  6. 9. pattern of evolution where unrelated species evolve similar traits even though they live in different parts of the world
  7. 11. selection is done by humans
  8. 12. random change in DNA that can change the allele frequency in a population
  9. 14. group or organism on a cladogram that shares the least amount of traits with the group
  10. 15. primitive traits found in ancestral and recent forms
  11. 17. effect where a few individuals from a population start a new population (1 word)
  12. 19. one of two types of speciation where species form in the same location (cichlids)
  13. 20. theory that describes slow incremental changes of species over long periods of time
  14. 23. the evolutionary process by which new biological species arise
  15. 24. a trait shaped by natural selection that increases an organism’s fitness
  16. 26. type of gene flow where individuals enter a new population
  17. 28. selective use or disuse evolutionist (last name)
