    Great Transitions Interactive: Human Origins

    Click & Learn

    Examine fossil skeletons and footprints of early humans and compare them to skeletons of modern humans and chimpanzees to discover how different traits have evolved over time.

  • New Laetoli Footprints and Hominin Body Size

    New Laetoli Footprints and Hominin Body Size

    Data Points

    Scientists were excavating a site in Laetoli, Tanzania when they uncovered two new sets of hominin tracks located about 150 meters south of the tracks found by Mary Leakey in the 1970’s. They estimated the heights of the two individuals using the size and shape of the footprints.

  • Patterns in the Distribution of Lactase Persistence

    Patterns in the Distribution of Lactase Persistence

    Card Activities

    Students explore the geographic distribution of lactase persistence around the world by analyzing real data collected by scientists.

  • 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.

  • Human Skin Color: Evidence for Selection

    Human Skin Color: Evidence for Selection

    Case Studies

    In this case study, students use real data to propose hypotheses, make predictions, and justify claims with evidence, as an exploration of concepts presented in the short film The Biology of Skin Color.

  • How We Get Our Skin Color Interactive

    How We Get Our Skin Color Interactive

    Interactive Videos

    (3 min 32 sec) This interactive animation about the biology of skin color provides stop points at which students can further explore the material through additional text and illustrations, videos, questions, and simple interactive widgets.

  • Human Feet Are Strange

    Human Feet Are Strange

    Labs & Demos

    In this activity, students examine concepts about the evolution of human bipedality explored in the short film Great Transitions: The Origin of Humans. They create their own trackway of footprints and compare it to a trackway of fossil footprints.

  • 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.

  • 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 Tool-Making Animal

    The Tool-Making Animal

    Scientists at Work

    (5 min 41 sec) Stone tools reveal a critical transition in the lives of our early human ancestors.
