SR A0S \Y I Y (o], LY o] @A) oo SESCOCORIIEB O 6B > Bl hhm! Biolnteractive Virtual Lab Lizard Evolution Virtual Lab Student Handout LIZARD EVOLUTION VIRTUAL LAB Answer the following questions as you finish each module of the virtual lab or as a final assessment after completing the entire virtual lab. Module 1: Ecomorphs 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? | based my criteria on the size of the anoles' legs. | did not revise my criteria later. | chose the size of the anoles' legs because | believe that each of the different anoles had evolved based on their habitat, and | wanted to base my experiment on that. 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 hispaniola anolis lizard. This is most likely due to the slim branch it lives on. The short legs make the lizard able to hold onto the branch/twig better and survive longer ecause it does not fall off. ?. %rov?c?e: one evolutionary exprlfanation 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. "eco" stands for ecological niche and "morph" for morphology, or shape. An example is how the sheplani Hispaniola and occultus Puerto Rico lizards both have short legs, but with slight. 5. How is an ecomorph different from a species? An ecomorph is different from a species because it only classifies the organism as having similar body types and habitats, however species have other different characteristics such as color or look. 6. Explain how a particular body feature of one of the lizard ecomorphs from the virtual lab is an adaptation to their particular niche. One of the lizard ecomorphs, the occultus Puerto Rico anole has short legs because it needs to be able to stick to/crawl on slim twigs in their habitat. www.Biolnteractive.org February 2015
