  • Sodium Channel Evolution in Electric Fish

    Sodium Channel Evolution in Electric Fish

    Data Points

    Scientists investigated how gene duplication contributed to the evolution of electric fish.

  • Understanding Variation in Human Skin Color

    Understanding Variation in Human Skin Color

    Lessons

    In this activity, students extend the concepts covered in the short film The Biology of Skin Color through the application of models and mathematical thinking to explain how genomic variation and human ancestry can explain differences in skin color, a polygenic trait.

  • Zebrafish and Skin Color

    Zebrafish and Skin Color

    Lessons

    This lesson complements the film The Biology of Skin Color and explores how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color.

  • Stickleback Film with Quiz

    Stickleback Film with Quiz

    Interactive Videos

    (15 min 27 sec) Embedded quiz modules test students’ understanding as they watch a short film that explains how stickleback fish let scientists study evolution in action, identify key genes, and peer deep into the evolutionary past.

  • Lactase Film with Quiz

    Lactase Film with Quiz

    Interactive Videos

    (14 min 52 sec) Embedded quiz modules test students’ understanding as they watch a short film that explores the evolution of the ability to digest lactose as adults (lactose tolerance) and the genetic changes associated with the trait.

  • Skin Color Film with Quiz

    Skin Color Film with Quiz

    Interactive Videos

    (18 min 58 sec) Embedded quiz modules test students’ understanding as they watch a short film that explores the evidence for the evolution of the variation in skin color among human populations.

  • Activity for The Biology of Skin Color

    Activity for The Biology of Skin Color

    Film Activities

    This activity explores the evidence that differences in human skin color are adaptations to varying intensity of UV light, as discussed in the short film The Biology of Skin Color.

  • Lactase Persistence: Evidence for Selection

    Lactase Persistence: Evidence for Selection

    Case Studies

    In this case study, students explore the story of the evolution of lactase persistence based on the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture and makes connections between genotype, phenotype, and culture using graphical analysis skills.

  • The Biology of Skin Color

    The Biology of Skin Color

    Short Films

    (18 min 58 sec) This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

  • The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture

    The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture

    Short Films

    (14 min 52 sec) This film explores the genetics and evolution of lactase persistence in humans.

  • Film Guides: Evolving Switches, Evolving Bodies

    Film Guides: Evolving Switches, Evolving Bodies

    Film Activities

    These classroom-ready resources complement the short film Evolving Switches, Evolving Bodies, which tells the story of the dramatic transformation of stickleback fish as they adapted to living in freshwater habitats drastically different from the ocean.

  • The Making of the Fittest: Evolving Switches, Evolving Bodies

    The Making of the Fittest: Evolving Switches, Evolving Bodies

    Short Films

    (15 min 27 sec) After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places like Alaska and British Columbia. These fish have adapted to a freshwater environment drastically different than the ocean.

  • Regulation of the Lactase Gene

    Regulation of the Lactase Gene

    Click & Learn

    Lactase persistence results from a mutation that changes how transcription factors interact, thereby affecting gene expression.

  • Molecular Genetics of Color Mutations in Rock Pocket Mice

    Molecular Genetics of Color Mutations in Rock Pocket Mice

    Lessons

    In these activities, students transcribe and translate portions of the rock pocket mouse Mc1r gene to further explore the genetic variations responsible for different coat colors as described in the short film Making of the Fittest: Natural Selection and Adaptation.
