This activity extends concepts covered in the film Got Lactase? The Co-evolution of Genes and Culture. Students infer whether someone is likely to be lactase persistent or nonpersistent based on the data from two different tests.
In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.
This lesson supports concepts covered in the film The Birth and Death of Genes. After watching the film and reading a couple of scientific passages, students explain how understanding about icefish adaptations might help develop treatments for health conditions.
This activity explores the research presented in the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have allowed some fish to adapt to extreme environments.
