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
Are Lizards cold or warm blood animals. If they are cold blood, it would make sense that they cannot be found in Antarctica
They are cold blooded I believe - a variety of modern scientists consider birds as a part of reptilia!
