    Moth Mimicry: Using Ultrasound to Avoid Bats

    Scientists at Work

    (10 min 24 sec) This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

  • Human Skin Color: Evidence for Selection

    Human Skin Color: Evidence for Selection

    Activity

    This case study is based on the short film The Biology of Skin Color. Students use real data to propose hypotheses, make predictions, and justify claims with evidence. Also available in Spanish.

  • Effects of Natural Selection on Finch Beak Size

    Effects of Natural Selection on Finch Beak Size

    Data Point

    Rosemary and Peter Grant studied the change in beak depths of finches on the island of Daphne Major in the Galápagos Islands after a drought.

  • Look Who's Coming for Dinner: Selection by Predation

    Look Who's Coming for Dinner: Selection by Predation

    Activity

    This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are asked to formulate a hypothesis, and collect and analyze real research data to understand how quickly natural selection can act on specific traits in a population. Also available in Spanish.

  • Evolution in Action: Data Analysis

    Evolution in Action: Data Analysis

    Activity

    These two activities support the film The Origin of Species: The Beak of the Finch. They provide students with the opportunity to analyze data collected by Princeton University evolutionary biologists Peter and Rosemary Grant.

    Short Film

    (15 min 54 sec) Four decades of research on finch species that live only on the Galápagos Islands illuminate how species form and multiply. Also available in Spanish.

  • Population Genetics, Selection, and Evolution

    Population Genetics, Selection, and Evolution

    Activity

    A hands-on activity that uses simulations with beads to teach students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. Also available in Spanish.

  • Allele and Phenotype Frequencies in Rock Pocket Mouse Populations

    Allele and Phenotype Frequencies in Rock Pocket Mouse Populations

    Activity

    A lesson that uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.

  • Color Variation Over Time in Rock Pocket Mouse Populations

    Color Variation Over Time in Rock Pocket Mouse Populations
