The Origin of Species: Lizards
in an Evolutionary Tree
Educator Materials
USING DNA TO EXPLORE LIZARD PHYLOGENY
OVERVIEW
This lesson serves as a supplement to the film Lizards in an Evolutionary Tree
...
They have evolved to
occupy different niches in the environment, and studying them is giving researchers surprising insights into
evolutionary processes, such as adaptation by natural selection, convergent evolution, and the formation of new
species
...
In Part 1, students
examine the diverse appearance of the lizards and group them into categories according to different body types
...
In Part 2, mitochondrial DNA sequence data from these same species of lizards are used to
generate a phylogenetic tree to reveal their true evolutionary relationships
...
Students watch
the film in stages at different points in the activity
...
Adaptive radiation occurs when an ancestral species diversifies into many descendant species that occupy
different environmental niches
...
DNA sequence comparisons among different populations and species allow scientists to determine the
degree of relatedness of different species
