1. Evolution – Station Reviews: Part One

2. Bell Work Explain what “Common Descent with Modifications” means.
Pick up today’s worksheet up front

3. Station 1: What were the earliest forms of life on the planet?
Bacteria
Archaebacteria
Eukaryotes

5. Station 2: Lamarck vs. Darwin
Which scientist was the first to hypothesize that organisms can change/adapt to their environments?
Which scientist hypothesized that organisms can acquire new traits based on their behaviors?
Which scientist hypothesized that the organisms best capable of surviving and reproducing would be most “fit” and therefore, the future of the populations would look more like that organism?

6. Station 2: Lamarck vs. Darwin part II
Which scientist is represented by the example picture 2a?
Which scientist is represented by the example picture 2b?
Which scientist hypothesized that all living organisms came from other living organisms that have adapted over time and therefore, all organisms share a common ancestor? (He called this Common Descent with Modifications)

7. Example Pic. 2a

12. Station 5: According to Darwin’s theory of evolution…
Every organism on the planet shares a common ancestor
Organisms can acquire traits through the use or disuse of certain body parts and pass those new traits onto their offspring
Every organism on the planet arose through spontaneous generation
Life began on the planet following the Big Bang 

13. Station 5:
This chart shows the number of amino acids that differ in a common protein found amongst mammals, called Cytochrome C. Using this chart, put the animals in order of how closely they are related to humans based on this comparison.

14. Station 6: What type of evolution does picture 6a show?
What type of structures would form from this type of evolution?
What type of evolution does picture 6b show?

18. Station 7: Which scenario shows divergent evolution occurring?
Which scenario shows convergent evolution occurring?
Which scenario shows coevolution occurring?

22. Station 8: Define Natural Selection in 4 words.
What determines which traits will be the most “fit”?
Fitness is defined as the ability to ____________ and ____________.
Using picture 8A, explain how bacteria are evolving antibiotic resistance via natural selection.
