Lizard's seem to be an interesting animal. I heared they can regrow their tale if they lose it.
I did not know this. Lizards are very widespread, and make up much of the reptilian kingdom
Do you know what their closest ancestor is?
I do not, unfortunately. It's true that they are very diverse in size, though - some only a few centimeters, with the Komodo dragon up to 3 meters.
That's right, I think there may be a relationship with dinosaurs 
That might be true! Apparently the physiology of dinosaurs has been heavily debated over the years
Yep, I think some of the morphological characters hint to that relationship.
Yes, that's probably true. Lizards share similar characteristics with them. I heard birds may be related to. Reptiles,unfortunately, cannot be found in Antarctica
