Скачать или смотреть Natural Selection with Peppered Moths | Evolution & Allele Frequency Lab

🦋 How did pollution during the Industrial Revolution change moth populations? In this AP Biology activity, we’ll explore natural selection in peppered moths and see how it connects to microevolution through changes in allele frequency over time.

In this lesson, you’ll learn:
Why evolution is defined as a change in allele frequency over time 🧬
How environmental change (soot-covered trees) shifted moth populations 🌳
How to calculate allele frequencies in each generation 📊
How to make bar graphs to visualize evolutionary change
How natural selection explains the shift in moth coloration

This activity ties together genotype, phenotype, and evolutionary fitness, making it a perfect AP Bio practice example.
