Adaptations and Evolution

Welcome! In this lesson, we will learn about adaptations and evolution.

---

Summary

■ Adaptations:

• Features or behaviors that help living things survive in their environment

■ Types of Adaptations:

• Physical → Body features (e.g., cactus stems)

• Behavioral → Actions or behaviors (e.g., birds migrating)

■ Evolution:

• Through natural selection, traits that help survival and reproduction are more likely to be passed on.

• Over many generations, these traits can become common in the species.
