  • Film Guide for The Biology of Skin Color

    Film Guide for The Biology of Skin Color

    Film Guides

    The following classroom-ready resources complement The Biology of Skin Color. Featuring anthropologist Dr. Nina Jablonski, the film walks us through the evidence that differences in human skin color are adaptations to varying intensity of UV light. Also available in Spanish.

  • Lactase Persistence: Evidence for Selection

    Lactase Persistence: Evidence for Selection

    Activities

    This activity provides a case study in human evolution that connects genotype, phenotype, culture, and graphical analysis skills. Also available in Spanish.
