Just-in-Time Teaching (JiTT) WarmUp Activity: The "Legs" of Snakes and Whales
2) Could snakes be linked to marine lizards? What your view and interpretations of the evidence?
3) Let's say I told you that I thought marine mammals evolved independently of land mammals (meaning, both originated on their own in separate environments with no linkages). What evidence would you use to argue that my viewpoint is incorrect (.... or is it really that crazy of an idea)?
