Set up Cornell Notes on pg. 3

Essential Question:
Why are the ideas that the Earth undergoes change and is billions of years old important for evolutionary theory?
10.1 Early Ideas About Evolution
2.1 Atoms, Ions, and Molecules
Why are the ideas that the Earth undergoes change and is billions of years old important for evolutionary theory?

3. Have you ever heard the expression of “survival of the fittest”?
Points to Ponder
Have you ever heard the expression of “survival of the fittest”?
What does it suggest to you?

4. KEY CONCEPT There were theories of biological and geologic change before Darwin.

5. EVOLUTION
Evolution-is a process of biological change by which descendants come to differ from their ancestors

7. A species is a group of organisms so similar to one another that they can reproduce (have babies) and have fertile offspring (babies who can have babies).

8. Early Ideas about Evolution (pg. 3)
Carolus Linnaeus
Georges Louis Leclerc de Buffon
Erasmus Darwin
Jean-Baptiste Lamarck . . . .

9. Warm Up
What Is Evolution? Define.
Define Species.
Name the theorists who propose the idea of evolution before Charles Darwin.

10. Carolus Linnaeus
Swedish botanist
Opened a classification system
for all types of organisms
He grouped them by their similarities
System reflects evolutionary relationships

11. Please classify these animals into groups based on their similarities.

13. Georges Louis Leclerc de Buffon
He proposed that species shared ancestors instead of arising separately
Rejected the idea that Earth was 6000 years old. He suggested that it was much older

14. Erasmus Darwin
Grandfather of Charles Darwin
Proposed that all living things descended from a common ancestor and that more-complex forms of life arose from less complex forms of life

15. Jean-Baptiste Lamarck
Proposed that all organisms evolved toward perfection and complexity
He did not think that species became extinct- He thought they evolved into different forms
Environmental change leads to use or disuse of a structure

16. Theories of Geologic Change (pg. 2) (p.299 in book)

Cuvier

Gradualism .
Catastrophism .

17. There were three theories of geologic change.
Catastrophism- natural disasters have happened often during Earth’s long history
These events shaped landforms and caused species to go extinct
Georges Cuvier

18. The Colorado River carving the Grand Canyon
2) Gradualism-slow changes over a long period of time
The Colorado River carving the Grand Canyon
James Hutton

19. 3) Uniformitarianism-Changes are uniform through time and occur at a constant rate
Charles Lyell

21. Uniformitarianism is the prevailing theory of geologic change.
