  • Sodium Channel Evolution in Electric Fish

    Sodium Channel Evolution in Electric Fish

    Data Points

    Scientists investigated how gene duplication contributed to the evolution of electric fish.

  • Pelvic Evolution in Sticklebacks

    Pelvic Evolution in Sticklebacks

    Data Points

    This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

  • Origins of Antibiotic Resistance

    Origins of Antibiotic Resistance

    Data Points

    This activity guides the analysis of a published scientific figure from a study on whether antibiotic resistance genes evolved before or after the introduction of modern-day antibiotics.

  • Mimicry in a Diverse Community of Arthropods

    Mimicry in a Diverse Community of Arthropods

    Data Points

    This activity guides the analysis of a published scientific figure from a study that tested how effectively mimicry protects arthropods against different types of predators.

  • 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.

  • 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) In this video, biologist Ken Dial demonstrates that birds use their wings for more than just flying, which may help us understand how dinosaurs used their small wing-like limbs before the evolution of flight.

  • Natural Selection and the Evolution of Darwin’s Finches

    Natural Selection and the Evolution of Darwin’s Finches

    Card Activities

    In this activity, students develop arguments for the adaptation and natural selection of Darwin’s finches, based on evidence presented in the film The Beak of the Finch.

  • Effects of Natural Selection on Finch Beak Size

    Effects of Natural Selection on Finch Beak Size

    Data Points

    This activity guides the analysis of a published scientific figure from a study that investigated evolutionary changes in seed-eating finches after a drought.

  • Weighing the Evidence for a Mass Extinction: In the Ocean

    Weighing the Evidence for a Mass Extinction: In the Ocean

    Card Activities

    This activity supports concepts covered in the short film The Day the Mesozoic Died by replicating observations and measurements made by researchers of fossilized protists, called foraminifera (or forams), below and above the K-T boundary.

  • Icefish Blood Adaptations: Viscosity

    Icefish Blood Adaptations: Viscosity

    Labs & Demos

    This hands-on lab activity serves as an introduction to the film The Birth and Death of Genes. Students simulate and compare how blood pumps through the circulatory system of icefish and other fish.

  • Icefish Blood Adaptations: Antifreeze Proteins

    Icefish Blood Adaptations: Antifreeze Proteins

    Labs & Demos

    This hands-on activity serves as an introduction to the film The Birth and Death of Genes. Students investigate the importance of antifreeze proteins for icefish survival through one of two short labs.

  • Color Variation Over Time in Rock Pocket Mouse Populations

    Color Variation Over Time in Rock Pocket Mouse Populations

    Card Activities

    This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates.
