Across
  1. 1. elimination of a species
  2. 4. 2 organisms change in order to form a specialized relationship
  3. 5. radiation/divergent evolution a number of different species from one common ancestor
  4. 6. equlibrium bursts of change followed by periods of stability
  5. 9. structures similar function, different structure
  6. 10. population shows different species on different islands
  7. 13. comparing similarities in DNA and AA sequences in different species to find common ancestry
  8. 16. tree diagram that predict the evolutionary relationship between organisms
  9. 19. structures structures with little or no function to the organism
  10. 20. remnants of animals
  11. 21. pool
  12. 24. random change in frequency of alleles in a population
  13. 25. reproduction process of binary fission or mitosis where only one parent produces offspring
  14. 26. reproduction takes 2 organisms to produce offspring
  15. 27. fossils fossils that link extinct species to current species
  16. 28. evolution unrelated species evolve similar characteristics
  17. 29. large scale
  18. 30. traits that arent good but necessary to reproduce
  19. 31. small scale
Down
  1. 2. Survival of the fittest
  2. 3. structures similar characteristics resulting from common ancestry
  3. 7. classifying and assigining each organism a name
  4. 8. the study of fossils
  5. 11. the structure of an organism
  6. 12. the embryos of vertebrates are very similar in appearance
  7. 14. movement of genes in or out of a population
  8. 15. forming of a new species by evolution from pre-existing species
  9. 17. slow changes over a long period of time
  10. 18. evolution,
  11. 22. no changes in the allele frequency of a population
  12. 23. evolutionary history of a species or group of a related species
