If you think birds are literally dinosaurs you should also think that every vertebrate is literally a fish.

Yeah, we're all fish.

Not really...alligators and crocodiles are though. Unchanged by evolution since the time of dinosaurs.

Actually birds literally are dinosaurs according to biology. And alligators and crocodiles are not. Dinosaur doesn't mean " an old species of reptile"

>Actually birds literally are dinosaurs according to biology. Careful - dinosaurs are birds according to at least one approach to biological classification. But not according to all of them. According to some, they are descended from dinosaurs, which does not necessarily mean they are classified as dinosaurs. It depends on which approach your using. Cladistically, they're dinosaurs. But that's not the only way to look at it.

You're right. But according to one classification they are indeed dinosaurs. Alligators and crocodiles aren't. That was my point

Sharks too.

I wasn't sure about them if certain species of sharks were around and unchanged. I know prehistoric ones existed like the megalodon, but was unsure great whites or whatever were around.
