are the dinosaours, really the ancestors of the birds?

Answer 1

It's a fact, the crow out side your house is a decendant ot the T-Rex. Heres a link to check out,

Answer 2

Ask your average paleontologist who is familiar with the phylogeny of vertebrates and they will probably tell you that yes, birds (avians) are dinosaurs. Using proper terminology, birds are avian dinosaurs; other dinosaurs are non-avian dinosaurs, and (strange as it may sound) birds are technically considered reptiles

Many scientists, including Thomas Henry Huxley (a staunch supporter of Darwin), saw incredible similarities between birds and the theropod dinosaurs (especially the coelurosaurs)

Some researchers today do not agree that dinosaurs gave rise to birds, and are working to falsify this theory, but so far the evidence for the theory has swamped their efforts. If they were to conclusively establish that birds are more likely descended from another group (Crocodylomorpha, the group containing crocodiles, has been suggested), that would be a major upheaval in our knowledge of phylogeny. One single well-preserved fossil bird unequivocably of Triassic age might shed some doubt on the theory of the maniraptoran affinities of birds.

lol, it is spelt "dinosaurs" not "dinosaours" check your spellings!!

Answer 3

It's hard to say without direct evidence of more proto-birds becoming mammals, but the fossil record seems to agree with this theory. Dinosaurs developed the characteristics that we see in birds long before the animals we know as birds existed. These are such things as hollow skeletons, specialized hip bones, and even feathers. The only other possibility for the evolution of birds is, like mammals, they evolved from a reptile that pre-dated the dinosaurs. However, this would suggest multipe occurances of similar features (like those mentioned above) in different species, which is not favored by chance evolution.

Answer 4

Many fossils that have been unearthed recently strongly suggest that some dinosaurs had feathers, and that while the majority of dinosaurs were killed off during a large natural disaster some survived and evolved into birds. The bones of dinosaurs such as raptors and the bones modern day birds are strikingly similar.

Answer 5

Many scientist beleive that birds did evolve from dinosaurs and some will argue otherwise. While there isn't realy a definitve answer to question, my belief is that birds did evolve from dinosaurs. There are several sources on the web on the subject. Check out http://www.ucmp.berkeley.edu/diapsids/avians.html and decide for yourself.

Answer 6

According to the science news that I've been reading, yes; dinosaurs really are the ancestors of birds. I hope this helps.

Answer 7

No. Keep in mind that reptiles never stop growing as long as they live. Before the Noahic flood thousands of years ago, people were living for hundreds of years. It reasons to figure that animals did the same. I think that dinosaurs are nothing more than offshoots of the reptiles we see on earth today.

Answer 8

Check tree of life ... birds and dinosaurs are classified as Archosaurs and share a strong phylogenetic relationship using several characters, including fossil evidence and molecular mapping.

Answer 9

The Houston Museum of Natural Science currently has an exhibit supporting this theory. To me, they seem to be. Here's a website that has both sides of the theory....

Answer 10

I am fascinated when I watch this on the History/Discovery Channel..They are several different versions on how they became extent, so how do they really know where they all came from?
