That crocodiles share a common ancestor with bird dolphins and dog support your answer?
Crocodiles and birds share a common ancestor. This can be seen by comparing the internal anatomy of the two. Dogs and Dolphins also have a common ancestor. Their skeletons again are both distinctly mammillian. The ancestor of dogs and dolphins and the ancestor of birds and crocodiles will again share a common ancestor, but you will need to go much further back. I am not sure of the timescales but we are talking tens to hundreds of million years.
Why is the dna of crocodiles is more similar to birds dna as compared to dna of turtles?
Simply put, birds are evolved from small dinosars, and dinosaurs belong to the same group that crocodiles belong to, archosauria, while turtles belong to the group sauropsida, because, while they appear to be more similar to crocodiles than birds, the evolutionary common ancestor they share is far more ancient, unlike that of crocodiles and dinosaurs. That's evolution for you.
Why do we think birds Evolved from crocodiles and alligators?
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.
What are the piranha's enemies?

What other reptiles are related to crocodiles?
Crocodilians are most closely related to birds, sharing a common ancestor with them in the archosaur group. Other reptiles that are distantly related to crocodiles include turtles, snakes, lizards, and tuataras.
Which trait suggests that crocodiles and birds share a common ancestor?
Both birds and crocodiles have a four-chambered heart and a system of air sacs for breathing not found in mammals or non-crocodilian reptiles. The fossil record also indicates a lineage from archosaurs for both.
Do birds and mammals inherit intelligence from a common ancestor?
yes
Do birds and reptiles share a common ancestor?
Yes. If you go back far enough, all life on Earth shares a common ancestor.
How are birds and a crocodile homologous?
Birds and crocodiles share the same ancestor... and so do dinosaurs. they are in the same clade. Both birds and crocodiles build nests, brood their eggs, "sing" to attract a mate and also have four chamber hearts. It has been reasoned that because the dinosaur, bird, and crocodiles all homolgous, dinosaurs TOO built nests, brooded their eggs, sang and also had four chamber hearts.
Why do crocodiles have a four-chambered heart?
Crocodiles may have had an ancestor that was starting down the path to being warm-blooded. Crocodiles are related to dinosaurs and their modern descendants, birds, which also have four-chambered hearts. The four-chambered heart allows for more efficient blood circulation.
What are the crocodiles relatives?
Crocodiles and other members of the group crocodilia are the dinosaurs closest living relatives.Crocodiles are somtimes refered to as ''living dinosaurs'', this is based on the idea that their anatomy hasn't changed much over millions of years. Crocodiles are not however dinosaurs themselves.Modern day Birds on the other hand ARE dinosaurs.Birds are a type of maniraptorian theropod dinosaur. Birds are the only dinosaur group to survive the mass extinction ~65million years ago. So therefore dinosaurs are Not extinct. (and they are doing quite well. There are approximately twice as many birds species than there are mammals.)Birds are therefore Crocodiles closest living relatives. And vise versa.Crocodiles and dinosaurs (+birds) are both members of the group Archosauria.Yes, both dinosaurs and crocodilians are archosaurs (the "ruling reptiles", they belong to the clade Archosauria, along with pterosaurs and some other closely related, but extinct, animals) and are therefore fairly closely related. Crocodiles however are NOT dinosaurs, nor did they evolve from dinosaurs (or vice versa) - they are simply related to them.
How long ago did birds and humans share a common ancestor?
300 million years.
