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.
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...
A simple activity that investigates the importance of antifreeze proteins to icefish survival.
A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.
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.
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...
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.
Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film.
Compare and contrast the anatomy of the heart and the circulatory systems of major vertebrate groups and gain insights into their evolution.
Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families.
