  1. Sci. 8 4-1 CIA REVIEW

  2. What is an adaptation? • A change in DNA • An over production of offspring • A competition between two members of the same species • A modification in a species for survival • I need help.

  3. Which of the following is true about the rate of evolution for most species? • Evolution can occur over a weekend • Evolution occurs in several months • Evolution occurs over one year • Evolution occurs over millions of years • I need help!

  4. If trees grew taller over time, what physical characteristics of giraffes would allow them to survive? • Thick neck • Thin neck • Long neck • Short neck • I need help!

  5. Which of the following is a result of adaptations over a long period of time? • Diversity within a species. • Competition within a species. • Extinction of a species. • I need help!

  6. Darwin’s studies of finches on the Galapagos Islands suggest that the finches’ differences in beak structure were most directly due to…. • Acquired characteristics in the parent finches • Mating behaviors of different finch species • Adaptations of the finches to different environments • I need help!

  7. Which of the following is better adapted for a water environment? • Hawk • Duck • sparrow B A. C

  8. Which of the following is a piece of evidence for evolution? a) Different body structures b) Similarities in early development c) Number of members of species d) Competition e) I need help!

  9. When some members of a species become isolated • They become extinct • They cannot reproduce • They are more likely to form a new species • Their population increases

  10. Diversity between individuals of a population or species is caused by: • Overproduction • Random mutations • Extinction • Gradualism
