Trivia: Which animal is the closest prehistoric relative to birds?
Crocodiles
Toads
Snakes
Chameleons
The correct answer is Crocodiles
So why is this answer correct? : Both birds and crocodilians descend from archosaurs, which means “ruling reptiles.” From this group came dinosaurs — the ancestors of birds — and crocodilians. However, over time, birds underwent a drastic evolution, whereas crocodiles remained relatively similar throughout the centuries.
