Across
  1. 2. when the average phenotype has the highest fitness
  2. 3. when the gene pool stays the same
  3. 9. humans getting taller is an example
  4. 10. everything that has happened will happen again
  5. 15. use radioactive isotopes to find this
  6. 17. individuals becoming less similar can lead to new species
  7. 18. life coming from other life
  8. 21. traveled on the Beagle and studied finches
  9. 24. all the alleles of a population
  10. 27. humans determine which traits are passed down
  11. 28. branch of similar organisms on a cladogram
  12. 29. having to fight to survive
  13. 30. number of offspring that survive to have offspring
  14. 34. age of Earth
  15. 35. most recent common ancestor on a cladogram
  16. 36. diagram that shows evolutionary changes
  17. 38. characteristic that is "used" becomes more pronounced in offspring
  18. 40. when two dissimilar species become more alike due to environment
  19. 41. one species quickly evolving into many species
  20. 43. studied butterflies and the Malay Archipelago
  21. 44. different songs are and example of this
  22. 45. can add new alleles to gene pool
  23. 46. layers of rock near the surface are younger than deeper layers
  24. 47. small population breaks off from main population and evolves faster
Down
  1. 1. indiv. moving in or out of population
  2. 3. similar looking structures
  3. 4. physical barriers between population
  4. 5. P + q = 1 is the equation for
  5. 6. figured by looking at layer of rock a fossil is found in
  6. 7. uneven survival in environment due to variance in population
  7. 8. when both extremes of a population have higher fitness than the average trait
  8. 11. two species so closely tied that if one changes the other species also will change
  9. 12. p2 +2pq + q2 + 1 is the equation for
  10. 13. any remnant of organism
  11. 14. change of a population/species to become more advanced
  12. 16. structures with similar functions
  13. 19. time needed for half an isotope to become stable
  14. 20. all species do this due to competition
  15. 22. using fossils to tell how tectonic plates moved
  16. 23. large population drops quickly and damages the gene pool even when the population returns to previous size
  17. 25. used S neck flask to prove that bacteria was in the air
  18. 26. thought giraffes stretched their neck to make them longer
  19. 31. different migration times are an example of this
  20. 32. number of a species in a place
  21. 33. when an individual chooses a mate- not at random
  22. 37. some of many small changes
  23. 39. disproved that maggots spontaneously arose from meat
  24. 42. another name for spontaneous generation
