  2. 3. An example of Both phenotype extreme
  3. 4. The evolutionary process by which one species gives rise to several species, each specialized for different environments.
  4. 5. What is it when structures from different species with similar functions BUT different evolutiona?y branches.
  5. 7. Organisms that only breed within their species, not with other species
  6. 8. what is it when they have to compete for food, mates, space, resources?
  7. 9. Evolution over a short period of time
  8. 13. What is it when 2 or more anatomical structures in different species that are similar and show how they evolved from a common ancestor
  9. 14. An example of 1 phenotype extreme
  10. 15. When alleles are eliminated from a gene pool usually due to a natural disaster.
  11. 16. changing environment (ex.weather) select for different phenotypes (ex. beak size)
  12. 17. An example of Intermediate phenotype
  13. 18. What shows evolutionary relationships and that all life evolved from Prokaryotic Bacteria?

  1. 2. The development of characteristics that enable an organism to better survive and reproduce in its habitat.
  2. 6. One ancestoral species(common ancestor) evolves into an array of different species, based on environment and genetic mutations that give an advantage in that particular environment.
  3. 10. When one species changes, and the other adapts
  4. 11. Original founder has a gene that is now prevalent in the current population.
  5. 12. What includes crossing over (meiosis) and random mutations,non-disjunction?
