3. Module 1. Ecomorobe a. Observe the morphologies of the eight different lizard species. For now, assume that you have just discovered these lizards and you don't even know if they are 8 different species or 1 species or some other number of species. You just have 8 lizards, 4 from each island. b. Following the module, group the lizards by morphology. i. How many groups did you find? ii. What sorts of traits or characters did you use to group the lizards? c. Then take some more careful measurements as shown and regroup them if needed. i. Did your measurements match the reference set? ii. Compare Lamellae Count, Relative Hindlimb Length, and Relative Tail Length among your specimens, and regroup your species based on these characters. iii. Did your groupings change? If so, how? iv. Watch the video to see if your conclusions match those of Dr. Losos
