Overview: In this set of lessons, students explore patterns of genetic diversity (DNA similarities and differences) in humans across the world. Students perform calculations using genetic data from actual studies, use data to detect patterns of diversity, and link processes to explain the patterns. They learn and reflect on how much all humans have in common, ways we differ, and how differences may or may not be related to where our ancestors lived.
 

Concepts: This lesson covers the following concepts:

• Introduction to Human Genetic Variation: introduces human genetic similarities and differences and how that compares to diversity in other species.
• Patterns of Genetic Diversity in Groups of People: explores genetic diversity in populations across the world.
• Patterns of Human Genetic Diversity across Continents: explores genetic diversity between people whose ancestors have lived on different continents for many generations.
• Explaining Patterns of Human Genetic Diversity: a deep dive into how major events in human history and evolution are reflected in patterns of diversity today.
