Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
In this classroom activity, students analyze data obtained from a research study to draw conclusions about the relationship between the number of copies of the salivary amylase (AMY1) gene and production of salivary amylase, which is the enzyme in saliva that digests starch. They also analyze the relationship between AMY1 gene copy number and dietary starch consumption among different populations.
This activity involves analyzing research data and graphing, using scientific reasoning to make claims, and using statistics to support these claims. It is intended for an advanced high school course (AP or IB) or undergraduate biology.
