When we see a crocodile’s gaping mouth and cold-blooded eyes, it’s not unusual to associate it with lizards. As a result, many people believe that there is some kind of evolutionary relationship between the two species.
In fact, when it comes to familial relationships, crocodiles are much more closer to avians than lizards. If you find it difficult to accept this relationship, why not picture those TV images of crocs floating lazily on the Nile, with Egyptian plovers cleaning their teeth? The relationship should be much more easier to swallow.
