Across
  1. 3. Have identical functions and look similar BUT develop differently and have different anatomy.
  2. 5. Darwin's Second Theory
  3. 7. How a species change over extended periods of time
  4. 8. Development of a new species, members can no longer breed with the population
  5. 10. a lot of genes passed on
  6. 11. a select few members of a population colonize a new habitat bringing with them their limited alleles.
  7. 12. individuals in center of distribution curve have highest fitness
  8. 13. Traits not determined by genes, but rather by experience or behavior
  9. 15. All species descended from one or a few common ancestors
  10. 17. Darwin traveled the world on this boat
  11. 19. Similar structures that originated in a common (same) ancestor.
  12. 22. The study of organisms and how they interact with the environment around them
  13. 23. an organism genetic contribution to the next generation.
  14. 24. The study of heredity
  15. 27. The branch of science concerned with classification
  16. 28. individuals at upper and lower ends of curve have more fitness
  17. 29. Organisms with similar origin become very different.
  18. 32. The study of life
  19. 33. Two organisms of different origin (having different ancestors) have similar traits
  20. 34. individuals at one end of distribution curve have higher fitness
Down
  1. 1. Manipulation of traits to promote desired traits
  2. 2. the lower the fossil, the older it is
  3. 4. organisms better suited for their environment will pass on their traits (reproduce) more successfully and so those traits become more common.
  4. 6. occurs when a disaster or disease strikes, leaving only a small remaining population.
  5. 9. Structures that were probably useful for ancestors, but have no function in modern organisms.
  6. 11. Darwin Studied what birds?
  7. 14. few genes passed on
  8. 16. #1 evidence of evolution
  9. 18. When two or more organisms increase in population because of each other.
  10. 20. Certain alleles become more or less common in a population
  11. 21. The more similarities in amino acids or DNA the closer the relationship between organisms.
  12. 25. 1st to hypothesize that similar species came from the same ancestor
  13. 26. Developed modern evolutionary theory
  14. 30. The study of embryos and how they develop
  15. 31. Members of a species compete for resources in the environment… Survival of the Fittest!
