  1. CIA 4-1 Learning Targets and Review Questions

  2. We are learning to explain that diversity of species is developed through gradual processes over many generations. • We are looking for how a species has changed to adapt to survive in its environment as evidenced by fossil records and present day organisms.

  3. 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

  4. 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

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

  6. 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.

  7. We are learning to: explain how variations in an organism allow it to reproduce successfully and survive in a particular environment. • We are looking for: the following variations: • How the organism is put together (structure) • How the organism acts (behavior) • What happens inside the organism that lets it live (physiology)

  8. In what way did the Galapagos finches vary? • Different color • Different beak structure • Size of bird • Change in type of foot

  9. 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

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

  11. We are learning to: explain that diversity of species is developed through gradual processes over many generations. • We are looking for: how a species has changed to adapt to survive in its environment as evidenced by fossil records and present day organisms. • We are learning to: describe how an organism adapted to a particular environment may become extinct. • We are looking for :evidence in the fossil record of the environmental change that caused an organism to go extinct

  12. How do scientists know that organisms have evolved? • Fossil record shows changes in organisms • Photographic evidence • Climate changes • Old written observations

  13. What can scientists learn from fossils? • Fossils show how life has changed on Earth • Fossils show how living things have stayed the same for many years • Fossils show that most organisms that lived millions of years ago still exist today • Fossils show that the Earth is only 6,000 years old.

  14. Which layer of rock has the oldest fossil? • Top layer • Middle layer • Bottom layer
