    Using DNA to Explore Lizard Phylogeny

    Card Activities

    In this activity, students explore the phenomenon of convergent evolution presented in the short film The Origin of Species: Lizards in an Evolutionary Tree. They build and interpret phylogenetic trees to infer how certain adaptations evolved among the Anole lizard populations of the Caribbean.

    Biodiversity and Evolutionary Trees

    Card Activities

    These two activities support the Click & Learn Sorting Seashells, in which students consider the morphological characteristics of seashells to construct an evolutionary tree. Students use seashell cards as a pre-activity to explore grouping organisms by shared characteristics. As a post-activity, they construct an evolutionary tree using DNA sequences.
