Unit 7: Evolution

Relevant Standard(s):

SB5. Students will evaluate the role of natural selection in the development of the theory of evolution. 
a. Trace the history of the theory 
b. Explain the history of life in terms of biodiversity, ancestry, and the rates of evolution. 
c. Explain how fossil and biochemical evidence support the theory. 
d. Relate natural selection to changes in organisms. 
e. Recognize the role of evolution to biological resistance (pesticide and antibiotic resistance).

Unit 7 Overview

Big Ideas:
1. how scientific theories are developed. 
2. chemical resistance as a modern example of biological evolution. 
3. the historical groundwork for the modern theory of evolution. 
4. historical evidence reveals the development of biodiversity through evolution. 
5. evidence for evolution is supported by fossils and biochemical examination. 
6. adaptations are necessary for survival. 
7. natural selection is facilitated by adaptations. 
8. evolution occurs due to processes of natural selection (i.e. adaptations and 
mutations). 
9. biological resistance is caused by mechanisms of evolution. 
10. evolutionary changes form the basis of modern classification systems.

Essential Questions:
1. What is the relationship between heredity and evolution? 
2. How do populations change over time? 
3. How are fossils, biochemical evidence, and anatomical structures used to support the 
theory of evolution? 
4. How have individuals and discoveries throughout history influenced the theory of 
evolution? 
5. How does selection pressure lead to phenotypic changes in populations? 
6. What are examples of evolution due to biological resistance?
