Patterns in the Distribution of Lactase Persistence
This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.
The activity begins with students watching the film. They then analyze data on the frequency of lactase persistence and associated alleles. The activity involves using the data to draw pie charts, place the pie charts on a world map, and identify patterns. It provides an interdisciplinary approach to studying lactase persistence by connecting biological concepts and data analysis to world geography and culture.
Student Learning Targets
- Calculate frequencies and graph data in pie charts.
- Interpret data from different research studies to infer the global distribution of a trait.
- Make claims based on scientific evidence and use scientific reasoning to support the claims.
