If some genes were exposed to microwaves, would that cause microevolution? In the video, scholars learn about microevolution or any change in the allele frequency of a population. The instructor explains the five ways microevolution works: small sample size, non-random mating, mutations, gene flow, and natural selection. It is the ninth video in a series of 18.

Instructional Ideas

• Place scholars in pairs and have them research one of the five mechanisms of microevolution and present findings to the class

Classroom Considerations

• Teacher must have a computer, access to the Internet, and a way to project the video in order to use the resource
• Video assumes learners understand allele frequency

Pros

• Video uses high-quality diagrams and photographs, making the material easy to understand
• Provides closed captioning to help individuals follow along with the content

Cons

• None
