Do birds have teeth ?

All living birds lack teeth. The ancient birds, such as Archaeopteryx, Microraptor, Anchiornis, and Sinornithosaurus have crocodile-like teeth. However, there are some mutant chicken embryos that can grow the same type of crocodile-like teeth. That is surprising because many people claim that birds evolved from a theropod dinosaur, so the ancient birds should have theropod teeth, not crocodile teeth. But, facts are facts, birds did not have the type of teeth they are supposed to have, perhaps because they did not know that they supposedly evolved from a theropod dinosaur. Someone should go back in time and tell them the type of teeth they should have.

Birds can be divided into two groups, the enantiornithines (or opposite birds) and the ornithurines. All modern birds descended from the ornithurine birds, while the enantiornithine birds were wiped out by the giant meteor that also wiped out the dinosaurs. Fossil evidence shows that these two different groups of birds evolved a toothless beak independently, because Confuciusornis, a fossil enantiornithine bird from China, had a beak. At around the same time Confuciusornis lived and also later, there were ornithurine birds that had teeth. That means the toothless beak did not evolve in the common ancestor of the ornithurine and enantiornithine birds, but it has evolved independently at least twice in the two great groups of birds.

No, birds do not have teeth. Yes, they evolved from dinosaurs which did have teeth, but over time they lost the need for teeth. They simply swallow everything whole.

There is an idiom; as rare as hen's teeth, because no birds actually have teeth.

I know i am wasting an reply here - however i will take the two aspects anyways: maybe DNA is like the tinker toys of construction - depending on what you want to happen, you tweak unique components of the DNA to make it occur - everything is product of DNA - or various it - and exclusive constituents get turned on and off to make the individual creations.... I'd additionally point out - evolution is a concept - it can not be verified as the beginning of life - it is called an "abductive procedure" - appear it up. It takes as much or more religion to believe that evolution is the origin of lifestyles as it does to suppose that God created the whole thing. Watch out while you say "each" scientist agrees with some thing - it is simply now not genuine. You certainly would not have much experience with the sciences.

Ducks, geese and swans have serrated edges on the bill that can rip into your skin if they bite you (I've experienced it), however most birds have straight edges on their bills and rely on pecking with the point or just clamping down in a bite (had a cardinal do that when I caught the one that flew in through an open window at work).

As for real 'teeth' set into bone of a jaw, no they do not.

Are'nt emus and ostriches birds because they have teeth, although maybe because they are large birds that can't fly they don't count!

I'm pretty sure they don't have teeth....

I don't think that

No.
