Transcript

  • 1. State Standard Review 12.4.3
  • 2.
    • ___________ is a change in a species over a long period of time.
    EVOLUTION
  • 3.
    • Evidence for evolution:
      • FOSSIL RECORD
      • HOMOLOGOUS STRUCTURES
      • SIMILAR EMBRYOS
      • SAME DNA/PROTEINS
  • 4.
    • If the bone structure in an animal becomes more advanced throughout the years it supports evolution because of the gradual change taking place.
  • 5.
    • ___________________________-
    • similar structures which indicate common ancestry
    HOMOLOGOUS STRUCTURES
  • 6.
    • Vertebrates are believed to have had common ancestry because there are marked similarities between the embryos of each class.
  • 7.
    • The same blood protein in a group of species provides evidence that the species descended from a common ancestor .
    Universal genetic code: SAME nitrogen bases code for SAME codons code for SAME amino acids code for SAME proteins
  • 8.
    • Is the only evidence for evolution in the fossil record?
    • NO
  • 9.
    • An ___________ is a trait that helps an organism survive and reproduce.
    ADAPTATION
  • 10.
    • ____________________ is the change in a population in which organisms with favorable variations live, reproduce, and pass on their favorable traits.
    Heavy duty beak Small beak NATURAL SELECTION
  • 11.
    • In evolution, BOTH environmental factors AND heredity play a role.
  • 12.
    • Factors which bring about changes in species over time:
      • Temperature
      • Space
      • Competition
  • 13.
    • Large populations aided by many mutations will provide the greatest potential for evolutionary change
  • 14.
    • In _________________________ it was thought that living things could arise from nonliving things.
    SPONTANEOUS GENERATION
  • 15.
    • Scientists think that the first cells resembled
    • _______________________
    PROKARYOTIC BACTERIA
  • 16.
    • Miller & Urey modeled atmospheric & temperature conditions on early earth to produce organic compounds .
  • 17.
    • Plants and animals w/ similar adaptations evolve in similar environments .
  • 18.
    • Organisms suited well to their environment reproduce more successfully than those less suited to the same environment.
  • 19.
    • Charles Darwin was the author of The Origin of Species.
  • 20. The Origin of Species
    • Darwin’s Journey on the H.M.S. Beagle
      • Explosed him to a variety of different ecosystems
      • His observations of these different ecosystems and the organisms that made up those systems led him to the conclusions found in this book.
