Original Prompt

A forest had a population of around 10,000 rabbits before a large forest fire. The rabbit population after the fire is around 300 rabbits. What statement is true about this scenario? Select {responseValue} This is an example of gene flow. The large decrease in the rabbit population will cause a decrease in the population’s genetic variation. Select {responseValue} This is an example of the bottleneck effect. The large decrease in the rabbit population will cause an increase in the population’s...

This Teacher Preparation Guide outlines a session designed for teaching students about evolutionary mechanisms, with particular emphasis on independent practice. The session duration is 30-45 minutes and aims to enhance students' understanding of how species change over time through mechanisms such as natural selection, genetic drift, and gene flow. The guide includes required materials for both teachers and students, focusing on activities that involve identifying specific mechanisms through case studies and practical scenarios like the forest fire and the evolution of the horse. Various practice problems are integrated to assess understanding, including visual representations of concepts and analysis questions about ladybug migration and Darwin's finches. The session encourages a focused learning environment where students can apply their knowledge to real-world examples, check their understanding, and self-assess their grasp of the material.
