The Molecular Evolution of Gene Birth and Death

Summary

An advanced lesson that describes the role of mutations in the birth and death of genes. It includes background information, examples, video clips, and animations.

Appropriate for: high school biology (second year, AP, IB), advanced high school genetics elective, introductory college biology, college-level genetics

This advanced lesson describes how mutation is a key element in both the birth and death of genes. Students proceed through a series of PowerPoint slides that include background information, examples, and embedded video and animation links. Questions challenge students to synthesize information and apply what they learn regarding how genes are gained and lost through evolutionary time.

Short Film
Scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
Film Guides
The following classroom-ready resources complement The Making of the Fittest: The Birth and Death of Genes, which describes how scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
Classroom Resource
A text transcript of the short film "The Birth and Death of Genes" from the Making of the Fittest short film series.
Classroom Resource
A lesson that requires students to read detailed scientific passages and explain how an understanding of specific icefish adaptations might lead to a treatment or cure for human disorders, such as osteoporosis and anemia. 
Classroom Resource
A dramatic demonstration that simulates how tiny ice crystals would form and grow in the blood of most fish if they ventured into the icy waters of the Antarctic.
Classroom Resource
A simple activity that investigates the importance of antifreeze proteins to icefish survival.
Classroom Resource
A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.
