  1. EVOLUTION REVIEW

  2. All are the same species and have one gene pool.

  3. Population

  4. He set sail on a 5 year voyage around the world after and is most known for developing what we know today as the Theory of Evolution.

  5. Charles Darwin

  6. The separation of populations by barriers such as rivers, mountains or bodies of water.

  7. Geographic isolation

  8. Name the type of selection occurring:

  9. Directional

  10. The MAIN contributing factor necessary for the formation of a new species.

  11. Reproductive isolation

  12. Needing to fight for Resources like food, Space and mates is referred to as the _________________.

  13. Survival of the fittest

  14. The three ways natural selection affects the distribution of a population.

  15. Directional Stabilizing Disruptive

  16. For natural selection to occur, there must be _________ happening in the environment.

  17. changes

  18. All the genes (or alleles) of all the members of a population

  19. Gene Pool

  20. What type of selection is occurring?

  21. Stabilizing selection

  22. Same bone structure is called _____________.

  23. Homologous structures

  24. Human tail bone is an example of these.

  25. Vestigial structures

  26. This is when individuals at only one end of a bell curve of phenotype frequencies have high fitness.

  27. Directional selection

  28. Name the two animals Darwin studied and published his ideas about and where he studied them?

  29. Finches and the tortoises • Galapagos islands

  30. A population of finches has two favorable traits for beak size-one group of birds has a short parrot-like beak and the other group has a long narrow beak. What natural selection process has occurred?

  31. Disruptive selection

  32. This increases the likelihood that at least some members of a species will survive under changed environmental conditions.

  33. Genetic variations

  34. A change in DNA

  35. Mutation

  36. This situation might develop in a population having some plants whose flowers release pollen midday and other plants whose flowers release pollen later in the day.

  37. Temporal isolation

  38. Name two sources of genetic variation

  39. Genetic recombination Mutations Gene flow

  40. How can behavior play a role in evolution?

  41. - Name one country other than USA where Mrs. P has lived.

  42. Where did Mrs. P go to college?
