Question1. Humans have quite a few instances of suboptimal design and evolutionary quirks. Like most animals, we have vestigial structures- things that evolved for a specific purpose at one point in our evolution, but are no longer useful for that purpose. What troublesome human organ is properly regarded as vestigial?

Question2. In Arizona, there live some strange little whiptail lizards that are one of the few parthenogenic reptiles- the females can lay fertile eggs all by themselves, without males. What odd quirk, explainable through evolution, do these lizards have?
