LS4B - Natural Selection

Paul Anderson explains natural selection, emphasizing its importance as a mechanism for evolution. He uses the peppered moth and bacteria as examples to illustrate how environmental changes and genetic variation lead to differential survival. The video also covers artificial selection and provides teaching strategies for different educational levels.

What is the definition of natural selection that the teacher wants students to remember?

How did the Industrial Revolution affect the population of peppered moths?

What are the two requirements for natural selection to occur?

How does variation in a population contribute to natural selection?

What example does the teacher give to illustrate natural selection in bacteria?

Describe how differences in organisms can lead to survival advantages, using giraffes as an example.

Explain the concept of artificial selection as described in the text.
