  • Think Like a Scientist: Natural Selection in an Outbreak

    Think Like a Scientist: Natural Selection in an Outbreak

    Scientists at Work

    (7 min 29 sec) This video focuses on the front lines of the 2013–2016 Ebola outbreak in West Africa and explains how scientists monitored the evolution of the virus by analyzing its genome.

  • 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.

  • Thermoregulation in Dinosaurs

    Thermoregulation in Dinosaurs

    Data Points

    Grady and colleagues compared dinosaur fossil evidence with evidence from living animal species to shed more light on the type of thermoregulation that dinosaurs used—ectothermy, endothermy, or mesothermy.

  • Origin of a Gene Mutation Causing Early-Onset Alzheimer’s Disease

    Origin of a Gene Mutation Causing Early-Onset Alzheimer’s Disease

    Data Points

    This activity analyzes a published scientific figure from a study of a family that has a high prevalence of Alzheimer’s disease.

  • Amylase Copy Number and Diet

    Amylase Copy Number and Diet

    Data Points

    A team of scientists investigated whether there is a correlation between the number of AMY1 gene copies and the type of diet (high-starch or low-starch) of a population.

  • 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.

  • The Origin of Flight: What Use Is Half a Wing?

    The Origin of Flight: What Use Is Half a Wing?

    Scientists at Work

    (8 min 16 sec) Biologist Ken Dial's study of how young birds use their developing wings sheds light on the evolution of flight in birds.

  • 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.

  • Schooling Behavior of Stickleback Fish from Different Habitats

    Schooling Behavior of Stickleback Fish from Different Habitats

    Data Points

    A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.

  • 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 Lone Anole

    The Lone Anole

    Phenomenal Images

    Students explore a photo of an anole lizard as a phenomenon to explore adaptations and natural selection.

  • Beaks As Tools: Selective Advantage in Changing Environments

    Beaks As Tools: Selective Advantage in Changing Environments

    Labs & Demos

    This classroom experiment supports the film The Origin of Species: The Beak of the Finch. Students collect and analyze data to learn why even slight variations in beak size can make the difference between life and death.

  • Activity for Lizards in an Evolutionary Tree

    Activity for Lizards in an Evolutionary Tree

    Film Activities

    This activity explores the concepts and research on the anole lizards discussed in the short film The Origin of Species: Lizards in an Evolutionary Tree, including adaptation by natural selection, convergent evolution, and the formation of new species.

  • Film Guides: The Origin of Species: The Beak of the Finch

    Film Guides: The Origin of Species: The Beak of the Finch

    Film Activities

    The following classroom-ready resources complement The Origin of Species: The Beak of the Finch. By following four decades of research on the finches of the Galápagos islands, the film illustrates how geography and ecology can drive the evolution of new species.
