Collect: HW: Reading & Notetaking p. 119 – 122
Science Fair Data Table & Graph presentations
Video: PBS Evolution – Great transformation
HW: Homologous Structures
Reminder: Science Fair Project Due 2/22 & 2/23 (50 Points)

2. Reflection
Prompt: Do you believe in evolution? Why or why not?

3. 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.

4. Comparison of Bonobos and Chimpanzees

5. Flores man was 3 feet tall
Lived in an Island in Indonesia 10,000 years ago
Lived with Dwarf Elephants

6. Gigantopithecus was 10 feet tall
Lived in SouthEast Asia 100,000 years ago.
Walked on all fours but can stand upright

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

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

9. 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

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

11. 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

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

13. The preserve remains or traces of an organism that lived in the past is called…
Fossil
Most fossils form when organism that die become buried in sediments
Remains of most animals never becomes fossil

14. How do fossils form?

15. Gradualism vs Punctuated Equilibria
Gradualism: The theory that evolution occurs slowly by steadily
Punctuated Equilibria:Evolution occurs during short periods of rapid change separated by long periods of little or no change

16. What are homologous structures?
Similar structures that related species have inherited from a common ancestor

17. Similarities in Early Development

18. Human Embryos have tails and gill slits

19. Reflection
Prompt: Write 5 interesting facts that you learned during the Science Fair Data Table, Graph and Procedure presentations.

21. Evolution Simulation

22. Evolution Video Isn’t Evolution Just a Theory? Who was Charles Darwin?
How Do We Know Evolution Happens?
