  • Understanding Variation

    Understanding Variation

    Activity

    This lesson complements the film The Biology of Skin Color and discusses variation in human skin color and polygenic inheritance. Also available in Spanish.

  • Zebrafish and Skin Color

    Zebrafish and Skin Color

    Activity

    This lesson complements the film The Biology of Skin Color and explores how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color.

  • Skin Color Interactive Video

    Skin Color Interactive Video

    Interactive Video

    (18 min 58 sec) Embedded quiz modules test students’ understanding as they watch a short film that explores the evidence for the evolution of the variation in skin color among human populations.

  • Film Guide for The Biology of Skin Color

    Film Guide for The Biology of Skin Color

    Film Guide

    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.

  • The Biology of Skin Color

    The Biology of Skin Color

    Short Film

    (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.

  • Icefish Film with Quiz

    Icefish Film with Quiz

    Interactive Video

    (13 min 14 sec) Embedded quiz modules test students’ understanding as they watch the short film on the icefish—an example of how genes are reused and recycled.

  • 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.

  • The Origin of Species: Lizards in an Evolutionary Tree

    The Origin of Species: Lizards in an Evolutionary Tree

    Short Film

    (17 min 45 sec) In the Caribbean islands, adaptation to several common habitats has led to a large adaptive radiation with interesting examples of convergent evolution. Also available in Spanish.

  • Regulation of the Lactase Gene

    Regulation of the Lactase Gene

    Click & Learn

    Lactase persistence results from a mutation that changes how transcription factors interact, thereby affecting gene expression.

  • Recent Adaptations in Humans

    Recent Adaptations in Humans

    Click & Learn

    Lactose tolerance, sickle cell anemia, and bitter taste perception are three examples of recently evolved human traits.

  • Creating Phylogenetic Trees from DNA Sequences

    Creating Phylogenetic Trees from DNA Sequences

    Click & Learn

    This Click and Learn explains how DNA sequences can be used to generate such trees, and how to interpret them. English version is ADA accessible.

  • The Making of the Fittest: The Birth and Death of Genes

    The Making of the Fittest: The Birth and Death of Genes

    Short Film

    (13 min 10 sec) Scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.

  • The Molecular Evolution of Gene Birth and Death

    The Molecular Evolution of Gene Birth and Death

    Activity

    An advanced lesson that describes the role of mutations in the birth and death of genes. It includes background information, examples, video clips, and animations.

  • Film Guides: The Birth and Death of Genes

    Film Guides: The Birth and Death of Genes

    Film Guide

    The following classroom-ready resources complement The Making of the Fittest: The Birth and Death of Genes, which describes how scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.

  • Molecular Genetics of Color Mutations in Rock Pocket Mice

    Molecular Genetics of Color Mutations in Rock Pocket Mice

    Activity

    A lesson that requires students to transcribe and translate portions of the wild-type and mutant rock pocket mouse Mc1r genes and compare sequences to identify the locations and types of mutations responsible for the coat color variation described in the film. Also available in Spanish.

  • Genetics of Human Origins and Adaptation

    Genetics of Human Origins and Adaptation

    Lecture

    (58 min 31 sec) Genetic evidence shows that humans evolved in Africa and continue to evolve.

  • The Y Chromosome

    The Y Chromosome

    Animation

    (2 min 46 sec) The Y chromosome has been likened to a hall of mirrors because its sequence contains many sections that appear to be palindromes. These palindromes provide a clue to some interesting events that may have occurred during the course of the chromosome's evolution.
