  • Developing an Explanation for Mouse Fur Color

    Developing an Explanation for Mouse Fur Color

    Activities

    Students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time. Also available in Spanish.

  • Mimicry in a Diverse Community of Arthropods

    Mimicry in a Diverse Community of Arthropods

    Data Points

    Researchers exposed arthropod mimics that use a golden patch to warn of unpalatability to predators with different prey preferences to determine how effective their warnings were.

  • Dating Corn Domestication Using Carbon Isotopes

    Dating Corn Domestication Using Carbon Isotopes

    Data Points

    To study the change in diet as human populations changed lifestyles from hunter-gatherers to agriculturalists, scientists measured carbon isotopes in the collagen tissues of human skeletons from North America.

  • Selection for Tuskless Elephants

    Selection for Tuskless Elephants

    Scientists at Work

    (6 min 39 sec) Working in Gorongosa National Park, Mozambique, Dr. Joyce Poole and colleagues made a striking observation: many female elephants lack tusks.

  • 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.

  • Selective Breeding in Maize

    Selective Breeding in Maize

    Data Points

    Researchers performed the longest-running, controlled artificial selection experiment to study whether they could increase the protein concentration of maize (corn) by selective breeding.

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

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

    Data Points

    A team of scientists built a pedigree of a large extended family in Antioquia, Colombia, that has a high prevalence of early-onset familial Alzheimer’s disease due to a mutation in the PSEN1 gene. Worksheets also available in Spanish.

  • Moth Mimicry: Using Ultrasound to Avoid Bats

    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

    Activities

    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.

  • Film Guide for Popped Secret: The Mysterious Origin of Corn

    Film Guide for Popped Secret: The Mysterious Origin of Corn

    Film Guides

    The following classroom-ready resources complement the film Popped Secret: The Mysterious Origin of Corn, which tells the story of how geneticists and archaeologists have come together to determine how and where corn was domesticated nearly 9,000 years ago. Also available in Spanish.

  • 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.

  • Effects of Natural Selection on Finch Beak Size

    Effects of Natural Selection on Finch Beak Size

    Data Points

    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.

  • 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) 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 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. 

  • Popped Secret: The Mysterious Origin of Corn

    Popped Secret: The Mysterious Origin of Corn

    Short Films

    (17 min 51 sec) Where did corn come from? Genetic and archeological data point to what may seem like an unlikely ancestor: a wild Mexican grass called teosinte. Also available in Spanish.

  • The Lone Anole

    The Lone Anole

    Phenomenal Images

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

  • Anthony Barnosky and Kaitlin Maguire Measure Mammal Extinctions at the John Day Fossil Beds

    Anthony Barnosky and Kaitlin Maguire Measure Mammal Extinctions at the John Day Fossil Beds

    Scientists at Work

    (9 min 15 sec) Prehistoric extinction rates are calculated from fossil data in a paleodatabase and compared to today’s extinction rate.

  • Beaks As Tools: Selective Advantage in Changing Environments

    Beaks As Tools: Selective Advantage in Changing Environments

    Activities

    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.

  • Evolution in Action: Data Analysis

    Evolution in Action: Data Analysis

    Activities

    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.
