  • Mate Choice in Spiders

    Mate Choice in Spiders

    Data Points

    Scientists investigated how males choose their mates in a species of sexually cannibalistic spiders.

  • Analyzing Data on Tuskless Elephants

    Analyzing Data on Tuskless Elephants

    Activities

    In this activity, students analyze data to investigate tusklessness in elephant populations.

  • 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.

  • 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.

  • 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

    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.

  • Natural Selection and the Evolution of Darwin's Finches

    Natural Selection and the Evolution of Darwin's Finches

    Activities

    In this activity, students develop arguments for the adaptation and natural selection of Darwin’s finches. Students use two key NGSS science and engineering practices: engaging in argument from evidence using mathematical and computational thinking, and analyzing and interpreting data.

  • 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.

  • 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.

  • 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.

  • Film Guides: The Origin of Species: The Making of a Theory

    Film Guides: The Origin of Species: The Making of a Theory

    Film Guides

    The following classroom-ready resources complement The Origin of Species: The Making of a Theory, which tells the story of the epic adventures of Charles Darwin and Alfred Russel Wallace and of the evidence they gathered for the theory of evolution by means of natural selection
