Original Prompt

Create a worksheet about the evolution of human illnesses. Include passages to address the following questions: Why do some adults have the ability to digest dairy? How do adults digest dairy products? What is the role of lactase in digesting dairy products? What role does DNA play in determining if a person can digest dairy after infancy? Why do some populations have the ability to digest dairy past infancy but others do not? Why would it be advantageous to consume the milk of other animals? H...

This learning resource explores how evolutionary biology can explain human health traits such as lactose tolerance and fat storage. It encourages students to analyze the genetic adaptations that have resulted from environmental pressures and to evaluate their modern health implications. Through guided reflections on the benefits of milk consumption in early agricultural societies, the importance of 'thrifty genes' in the context of today's calorie-rich environments, and challenges in modern medicine (like antibiotic resistance), students are equipped to apply their understanding of natural selection and genetic variation to real-world health scenarios. The resource includes key vocabulary, figures, and questions that promote deeper engagement with the content.
