LIZARD EVOLUTION VIRTUAL LAB
Directions: Begin in the Introduction Tab. Read the Introduction and watch the Welcome to the Lizard
Evolution Lab. Answer the following questions as you finish each module of the virtual lab.
Click on Module 1: Ecomorphs and follow the directions as you work through the information.
1. At the beginning of the virtual lab, you were asked to sort eight lizards into categories. What
criteria did you initially use to make your groups? Did you revise your criteria later? Why?
I based my criteria off of the legs. I chose the size of the legs because I think that each of the different
anoles had evolved based on their habitat. I did not revise my criteria.
2. An adaptation is a structure or function that is common in a population because it enhances the
ability to survive and reproduce in a particular environment. Provide one example and an
explanation of one adaptation in the Anolis lizards. One adaptation is the short legs on the
sheplani hispanola anolis lizard. I think this is because of the slim branches it was on. The shorter
legs made it easier for the lizard to hold onto the slimmer branches.
3. Provide one evolutionary explanation for why lizards living in the same part of the habitat (i.e.,
grass) would have similar characteristics. Lizards in the same habitat would have similar
characteristics because there are many ways to do something, however there is only one way
that is the best for surviving. Basically, lizards in the same habitat have the characteristics that
are most fit for survival, so most lizards in that habitat would exhibit those most fit
characteristics.
4. What is an ecomorph? Provide one example from the virtual lab. Ecomorphs are species with
similar body types and habitats. An example is how the sheplani Hispaniola and occultus Puerto
Rico lizards both have short legs
