# What is natural selection?

In the previous module, we observed how different traits in a peppered moth population increased or decreased based on human impact on the environment. Now, you will read an article and watch a video about how natural selection drives the evolution of organisms. The article and video will help explain how the peppered moth simulation relates to genetics and the effects of genetic drift. Be sure to continue adding notes to your brainstorming document as you work through these activities.

## Procedure

1. Follow the instructions on the Natural Selection Choice Board.
2. Add your notes on the main ideas from the article and video to your brainstorming document.
