  • How Novel Icefish Genes Can Improve Human Health

    How Novel Icefish Genes Can Improve Human Health

    Activities

    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. 

  • Demonstration: Viscosity of Icefish and Non-Icefish Blood

    Demonstration: Viscosity of Icefish and Non-Icefish Blood

    Activities

    A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.

  • Icefish Adaptations

    Icefish Adaptations

    Activities

    A simple activity that investigates the importance of antifreeze proteins to icefish survival.

  • Film Guides: The Birth and Death of Genes

    Film Guides: The Birth and Death of Genes

    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.

  • Molecular Genetics of Color Mutations in Rock Pocket Mice

    Molecular Genetics of Color Mutations in Rock Pocket Mice

    Activities

    A lesson that requires students to transcribe and translate portions of the wild-type and mutant rock pocket mouse Mc1r genes and compare sequences to identify the locations and types of mutations responsible for the coat color variation described in the film. Also available in Spanish.

  • Pitx1 Expression

    Pitx1 Expression

    Animations

    (55 sec) In the stickleback fish, pelvic-fin reduction resulted from changes in the regulatory switch elements of the Pitx1 gene. In the marine ancestor, the Pitx1 gene is activated in the pelvic-fin region during development to generate the fin. In the pelvic-reduced stickleback, the regulatory switch that normally turns on the Pitx1 gene is either missing or non-functional.

  • Fossil Record of Stickleback Evolution

    Fossil Record of Stickleback Evolution

    Clips

    (2 min 34 sec) A quarry site in Nevada carries the evolutionary history of a population of stickleback fish that resided there when it was a freshwater lake.

  • Clonal vs Sexual Reproduction

    Clonal vs Sexual Reproduction

    Clips

    (8 min 56 sec) What does a stack of fruits and vegetables have to do with the theoretical advantages of sexual reproduction? Find out in this demonstration with student audience members and Dr. David Page.
