Lactose Intolerance: Fact or Fiction

Summary

Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film.

Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film.

This activity can be used as an anticipation guide to focus students on several of the key concepts presented in the film. It can also serve as a pre- and post-assessment.

Appropriate for middle school life science and all levels of high school biology.

Supporting Materials (7)

Short Film
Follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults, tracing the origin of the trait to less than 10,000 years ago, a time when some human populations started domesticating animals.
Film Guides
The following classroom-ready resources complement Got Lactase? The Co-evolution of Genes and Culture, which tells the story of the evolution of the ability to digest lactose, a genetic trait that arose in humans within the last 10,000 years in some pastoralist cultures.
Classroom Resource
Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families.
Classroom Resource
Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
Classroom Resource
Students interpret the results of two different tests for lactase persistence.
Classroom Resource
A text transcript of the short film "Got Lactase? The Co-evolution of Genes and Culture" from the Making of the Fittest short film series.
Classroom Resource
Students simulate a lactose tolerance test.
