Darwin

Today, we will discuss Darwin and Evidence of Evolution

Carl Sagan

Pre-Darwinian Theories of the Modern World

Today, we'll explore the evolution of Evolution Theory!  There were a number of scientists leading up to the time of Charles Darwin that contributed to the development of the scientific method and evolutionary theory.  

James Ussher
Carolus Linnaeus
John Ray
Comte de Buffon
Erasmus Darwin
George Cuvier
Charles Lyell
James Hutton

As we discuss each scientist, we'll discuss their contributions using these questions as a guide.

1. In what time period did your scientist live?
2. What branch of science did your figure study?
3. What was this person's primary contribution to scientific study?
4. How did his theories affect the development of evolutionary theory?
5. What was the importance of The Great Chain of Being?
6. How did it differ from Linnaeus' System of Classification?

Read and fill out the worksheet on Lamarck's view of evolution.

Evolution

Objectives

• To define evolution
• To contrast the theories of Lamarck and Darwin
• To explore how evolution works within nature

Although some support the theory of creationism, physical anthropology rests on the principles of evolution.  This section of the course does not seek to change anyone's theological viewpoints.  A better understanding of evolution will support your understanding of the way that Anthropologists work and how they have determined the history of the human being.  We can discuss this further in class if there are differences in opinion, but it must be a respectful discussion as everyone is entitled to their own beliefs.  Remember that we are studying the larger view of the human species and not the micro view of the individual.

Please look at Dennis O'Leary's tutorial on evolution and watch the shorter clips today. 

Today we will discuss the conflicting theories presented by Lamarck and Darwin, the problems presented by Lamarck and look at examples of how natural selection operates in the natural world.



                                            

How did Giraffes become long-necked?

Read the Handout about Lamarck and answer the questions in groups of two or three.

Read the Handout about Darwin and answer the questions in groups of two or three.

Finally, take a stab at describing how each animal evolved according to Darwinian theory on the last Handout.


For extra credit, please read the following links about the Scopes Monkey Trial of 1925 and briefly present a summary of the case and why it was important, either in writing, presentation to the class or privately to me!
