    Birds are the only dinosuaurs on the planet.

    Its not a matter of dinosaurs evolving, but of the DNA of a particular animal being best adapted to its environment. Dinosaurs had the best DNA (and what a variety!) to be the top of the food chain/web in the Jurassic period; during that time there were undoubtedly other organisms that had DNA that in the future would best adapt them to be modern birds. It is somewhat rare that we can actually trace the decendence of a particular animal from one organism to another. The fact that we can find fossils of reptiles with some bird characteristics seems to indicate that they shared an ancestor, but does not conclusively define dinosaurs as the ancestors of birds.

    Definitely not.

    Even using evolutionary dating methods - birds have been found that are 'older' than dinosaurs.

    Of course, there is no evidence that any kind of animal has evolved into any other kind of animal. Natural Selection, yes. Goo-to you evolution - no.

    A bird requires many unique features to be able to fly - and it needs them all at once! They can't have evolved bit by bit. For example: lightweight bones, feathers with hooks and barbs (like velcro), and feathers are quite unlike reptilian scales, an oil gland for the feathers, an avian lung - completely different to any other kind of lung, etc. The idea that a bird evolved from a non-bird is ludicrous when you take a close look.

    Many news agencies have reported (June 1998) on two fossils found in Northern China that are claimed to be feathered theropods (meat-eating dinosaurs). The fossils, Protarchaeopteryx robusta and Caudipteryx zoui, are claimed to be ‘the immediate ancestors of the first birds.’12

    The two latest discoveries are ‘dated’ at 120 to 136 million years while Archaeopteryx, a true bird, is ‘dated’ at 140 to 150 million years, making these ‘bird ancestors’ far younger than their descendants!

    (Daniel R and talk origins are talking a load of baloney - check the evidence for yourself. There is definitely not a complete set of transitional fossils. Evolutionary expert Feddccia has demonstrated dino to bird evolution os false.)

    dinosaurs are more closely related to birds then to reptiles. however not all dino's ''evolved'' into birds. for example the shark and crocodile/alligator were around during the time of the dinosaurs. but obviously not the same they have changed some to better increase there chance of survival.

    Not all dinosaurs evolved into birds. Imagine what T-Rex would look like as a bird. Dinosaurs evolving into birds is just a theory but scientists discovered that saurs like raptors had some feathers. Also, dinosaurs have similar structures to birds or vise versa.

    The entrance to the bird exhibit at the Cincinnati zoo in Ohio has or had a sign that said: “Dinosaurs went extinct millions of years ago—or did they? No, birds are essentially modern short-tailed feathered dinosaurs.”

    First of all, bird evolution is one of the most controversial areas in evolutionary paleontology and evolutionists often disagree and criticize each other.

    We hear a lot of reports of feathered dinosaurs being found, but what you rarely hear, is that the main candidates are believed by many experts to simply be frayed collagen fibers, or hair like structures that could have supported a frill or crest like those on iguanas, or are on animals that are not dinosaurs, but flightless birds. The drawings are certainly not what we find; they are just the artists’ imagination. Dr. Alan Feduccia, a world authority on birds and an evolutionist, along with his coworkers have presented a substantial body of evidence to support their view that there are, in fact, no known dinosaurs with feathers (they believe birds evolved from different reptiles, but not dinosaurs).

    And then you have ones like Archaeoraptor that was proven to be a hoax. Who knows how many times that will happen.

    All these announcements of feathered dinosaurs cause a lot of media fanfare, but when they are refuted, there is scarcely a whimper in the media. There is usually a deafening silence when the latest “evidence” for evolution joins the long list of items which are no longer believed by evolutionists themselves.

    You may be thinking, “But what about Archaeopteryx? That has been used for years and years.” Archaeopteryx was a true perching bird with fully formed wings and flight feathers, as well as a large wishbone for the attachment of muscles used for the downstroke of the wings.

    So what is all the fuss about; why is Archaeopteryx such an icon of evolution? Well, it had teeth in the bill, claws on the wings, no keel on the breast bone, an unfused backbone, and a long, bony tail, which are all characteristics most people associate with reptiles.

    But as Dr. Gary Parker said, “...the reptile-like features are not really as reptile-like as you might suppose. The familiar ostrich, for example, has claws on its wings that are even more ‘reptile-like’ than those of Archaeopteryx. Several birds, such as the hoatzin, don’t have much of a keel. The penguin has unfused backbones and a bony tail. No living birds have socketed teeth, but some fossil birds do. Besides, some reptiles have teeth and some don’t, so the presence or absence of teeth is not particularly important in distinguishing the two groups.”

    Dr. Alan Feduccia (like I said, an evolutionist, and by the way, one who doesn’t like creationists quoting him) said, “Paleontologists have tried to turn Archaeopteryx into an earth-bound, feathered dinosaur. But it’s not. It is a bird, a perching bird. And no amount of ‘paleobabble’ is going to change that.”

    On top of that, scientists have found fossils of what they would call “true birds” in layers of rock that they date as being older than Archaeopteryx. That presents a problem for them.

    I believe Archaeopteryx was something of a mosaic like a bat or platypus. Similar structures simply point to a common designer. God knew what designs would work well in multiple animals. What they need to find, is a fossil showing scales turning into feathers, or a leg turning into a wing, or the reptile lung turning into the avian lung. How you can take a “two-way” reptile lung and evolve it into a fully functional “one-way” bird lung without causing extinction of the species is quite a conundrum.

    There is no credible evidence that dinosaurs evolved into birds. Dinosaurs have always been dinosaurs and birds have always been birds.

    I'm sure some of the flying didosaurs evolved, but the cute little lizard isn't a bird.

  • 1 decade ago

    some dinosaurs evolved into birds by modifying their reptilian scales into feathers.

    other dinosaurs developed directly into mammals.

    I believe you're refering to the fossil Archaeopteryx, which is consider a link in terms of evolution between dinosaurs and birds.

  • 1 decade ago

    Yes, they did. Scientists have found a whole set of intermediate fossils - including the famous Archeopteryx, but also many others that clearly detail the progression from dinosaur to bird. See http://www.talkorigins.org/faqs/comdesc/section1.h... for a list.
