All birds evolved from the raptor family of therapod dinosaurs.
AnswerPossibly none. Birds do have many features in common with theropods (bipedal carnivorous dinosaurs) which suggests that they had a common ancestor. We dont know that this common ancestor was a dinosaur though. It may well have been a bird (see related links).Looking back in time through the theropod fossil record, these dinosaurs appear to be more bird-like the further back in time you look. Raptors are known to have had feathers and were fairly bird-like, but Archaeopteryx was much more bird-like and lived much earlier and may have been an ancestor of the raptors. There is also a controversial fossil called Protoavis that was dated even earlier and was more bird-like still, with hollow bones like modern birds.
So birds may have been around throughout the mesozoic era and pre-date the dinosaurs. We have little record of them though because their hollow bones mean that few fossils survive to the present day.
Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Birds are more like dinosaurs to the extent that many scientists say that they are dinosaurs.
Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
they didn't. they evolved into birds.
They evolved from dinosaurs.
Birds. The reason is that both crocodiles and dinosaurs are archosaurs, and birds evolved from dinosaurs.
Birds evolved from small reptiles that lived during the age of dinosaurs, but not from the dinosaurs themselves.
No. It's the other way around. A branch of the dinosaurs evolved into birds.
Dinosaurs came before birds, because dinosaurs later on evolved into birds, therefore, making birds come along LATER then the dinosaurs. However dinosaurs were far from the first creatures on earth.
