  • Developing an Explanation for Mouse Fur Color

    Developing an Explanation for Mouse Fur Color

    Activity

    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. 

  • The Search for a Mutated Gene

    The Search for a Mutated Gene

    Scientists at Work

    (8 min 54 sec) How do you identify the disease-causing mutation in a patient with an inherited disease? This video illustrates the steps involved—testing for genes that are the “usual suspects,” searching for mutations in novel genes, and assessing links between genotype and phenotype.

  • Using Genetic Evidence to Identify Ivory Poaching Hotspots

    Using Genetic Evidence to Identify Ivory Poaching Hotspots

    Data Point

    A team of scientists analyzed the DNA from seized ivory to determine where the ivory from poached elephants came from.

  • CSI Wildlife

    CSI Wildlife

    Click & Learn

    In this interactive, students use DNA profiling, or fingerprinting, to solve two cases of elephant poaching. In the process they will learn about genetic markers, PCR, gel electrophoresis, allele frequencies, and population genetics.

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

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

    Data Point

    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.

  • Identifying Autism Genes by Tracking Gene Mutations

    Identifying Autism Genes by Tracking Gene Mutations

    Data Point

    A team of scientists used homozygosity mapping to map SNPs on chromosome 3 in a family with an autistic son to identify a likely gene that caused the disorder.

  • The Teosinte Hypothesis

    The Teosinte Hypothesis

    Activity

    In this lesson, students work through the mathematics and concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize. Also available in Spanish.

  • Genetic Origin of Variation in Human Skin Color

    Genetic Origin of Variation in Human Skin Color

    Data Point

    Dr. Rebecca Lamason and colleagues studied the genetic origin of variation in human skin color using a model organism, the zebrafish.

  • How Species Coexist

    How Species Coexist

    Lecture

    (27 min 25 sec) Large herbivores in the African savanna coexist by partitioning ecological niches by time, space, and diet.

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

    Film Guide for Popped Secret: The Mysterious Origin of Corn

    Film Guide

    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.

  • Lactase Persistence: Evidence for Selection

    Lactase Persistence: Evidence for Selection

    Activity

    This activity provides a case study in human evolution that connects genotype, phenotype, culture, and graphical analysis skills. Also available in Spanish.

  • Pulse Chase Primer: The Meselson-Stahl Experiment

    Pulse Chase Primer: The Meselson-Stahl Experiment

    Activity

    This activity can be used in conjunction with the short film The Double Helix. It introduces students to the classic experiment by Matthew Meselson and Franklin Stahl, which revealed that DNA replication follows the semiconservative model.

  • Using DNA to Explore Lizard Phylogeny

    Using DNA to Explore Lizard Phylogeny

    Activity

    This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are guided to sort the lizard species by appearance, then generate a phylogenetic tree using the lizards’ DNA sequences to evaluate whether species that appear similar are closely related to each other.

  • Testing a Hypothesis

    Testing a Hypothesis

    Activity

    A worksheet designed to actively engage students as they watch the film. Students are asked to answer questions pertaining to the information provided in the film.

  • Bones, Stones, and Genes: The Origin of Modern Humans

    Bones, Stones, and Genes: The Origin of Modern Humans

    Lecture

    Where and when did humans arise? What distinguishes us from other species? Did our distant ancestors look and behave like us?

  • Evolution: Constant Change and Common Threads

    Evolution: Constant Change and Common Threads

    Lecture

    How has the amazing diversity of plants and animals evolved? What can fossils, butterflies, and stickleback fish tell us about the deep common ancestry of all living forms?

  • Learning from Mice: The Science of Transgenic Technology

    Learning from Mice: The Science of Transgenic Technology

    Clip

    (11 min 8 sec) What do humans, flies, and worms have in common? More than you might think. See how transgenic organisms are engineered, and how they enable researchers to study genetic diseases.
