Across
  1. 2. branch of similar organisms on a cladogram
  2. 5. when an individual chooses a mate- not at random
  3. 7. similar looking structures
  4. 8. humans determine which traits are passed down
  5. 13. some of many small changes
  6. 15. life coming from other life
  7. 17. traveled on the Beagle and studied finches
  8. 18. one species quickly evolving into many species
  9. 19. individuals becoming less similar can lead to new species
  10. 22. used S neck flask to prove that bacteria was in the air
  11. 24. small population breaks off from main population and evolves faster
  12. 28. all the alleles of a population
  13. 29. another name for spontaneous generation
  14. 31. characteristic that is "used" becomes more pronounced in offspring
  15. 32. age of Earth
  16. 33. diagram that shows evolutionary changes
  17. 35. P + q = 1 is the equation for
  18. 36. two species so closely tied that if one changes the other species also will change
  19. 37. structures with similar functions
  20. 38. large population drops quickly and damages the gene pool even when the population returns to previous size
  21. 39. having to fight to survive
  22. 40. layers of rock near the surface are younger than deeper layers
  23. 42. thought giraffes stretched their neck to make them longer
  24. 44. uneven survival in environment due to variance in population
  25. 45. different songs are and example of this
  26. 46. when the gene pool stays the same
  27. 47. when the average phenotype has the highest fitness
Down
  1. 1. everything that has happened will happen again
  2. 3. when both extremes of a population have higher fitness than the average trait
  3. 4. all species do this due to competition
  4. 6. humans getting taller is an example
  5. 9. figured by looking at layer of rock a fossil is found in
  6. 10. change of a population/species to become more advanced
  7. 11. time needed for half an isotope to become stable

  14. 25. when two dissimilar species become more alike due to environment
  15. 26. use radioactive isotopes to find this
  16. 27. any remnant of organism
  17. 30. using fossils to tell how tectonic plates moved
  18. 32. number of offspring that survive to have offspring
  19. 34. physical barriers between population
