2. Reflection
Prompt: Write 3 questions that you have about Evolution.

3. Who first proposed the Theory of Evolution?
Darwin

4. What is Evolution?
Gradual change in a species over time through a process of natural selection.

5. Why would finches have different types of beaks?
Finches that ate insects had sharp, needlelike beaks
Finches that ate seeds had strong wide beaks

6. Why would iguanas have different color skins?
Because they need to adapt to different conditions.
Green Iguanas live in the jungle and Marine Iguanas live on rocks.

7. What is Natural Selection?
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species

8. Which Beetle is most likely to survive?

9. What are the factors that affect the process of natural selection?
Overproduction
Competition
Variations
Selection

10. When does a new species form?
A new species can form when a group of individuals remains separated from the rest of its species long enough to evolve different traits.

11. Did humans evolve from chimpanzees?NO
Humans did not evolve from chimpanzees. Humans and chimpanzees are evolutionary cousins and share a recent common ancestor that was neither chimpanzee nor human.
Humans are not "higher" or "more evolved" than other living lineages.

12. Can evolution be described as a tree or a ladder?

13. Fossils in which minerals replace all or part of an organism is called…
Petrified Fossils

14. Most Common Fossils are Molds and Casts. What are they?
Mold: Hollow in shape and are formed when an organism buried in sediment dissolves
Cast: Copy of an organism’s shape formed when minerals seep into a mold
Dinosaur Foot Print

15. What is a carbon film fossil?
Carbon film is an extremely thin coating of carbon on rock.

16. What are Trace Fossils?
Trace Fossils provide evidence of the activities of ancient organisms. Such as Dinosaur foot prints
Megalosaurus footprint A meat eating predator from the Jurassic

17. What are some of the ways that extinct animals can be preserved with little or no change?
Amber
Freezing
