    (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.

  • Film Guide for The Biology of Skin Color

    Film Guide for The Biology of Skin Color

    Film Guide

    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

    Activity

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

  • The Biology of Skin Color

    The Biology of Skin Color

    Short Film

    (18 min 58 sec) Penn State University anthropologist Dr. Nina Jablonski walks us through the evidence that the different shades of skin color among human populations arose as adaptations to the intensity of ultraviolet radiation in different parts of the world. Also available in Spanish.

  • 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 Film

    (14 min 52 sec) 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. Also available in Spanish.

  • 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.
