HERE I wrote about a man who was critiquing the director of Jurassic Park 4 for deciding not to put feathers on his dinosaurs. In the comment section, debate started. If you read but a few of those comments you can instantly see that dinosaur-to-bird evolution is naturally assumed.But, let’s say that, by some stroke of chance, that dinosaurs did get perfect feathers, what else would they need to change?
Beside the feather dilemma, evolutionists also have a problem with the organs and structure of birds compared to dinosaurs. In order to truly see if dinosaurs evolved into birds it is important we discuss these structures.
If we were to assume that dinosaurs did evolve feathers they still had the problem of wings. Theropod dinosaurs, the kind birds supposedly evolved from, are famous for their big back legs and small arms.
These arms were not long enough or capable of feeding the theropods (the supposed ancestors of birds) and they do not look strong enough to walk on. It is proposed that theropods may have used their arms to hunt (grasp prey after jumping them). But, what they certainly could not do is flap with them, even if they had feathers; the joints and position of them were just too off to effectively flap.
The lung of the bird is quite an amazing feature known only to its kind. When a bird breathes, air does not go down into its lungs then back up and out like that of humans or mammals but flows in a straight direction, like air through a tube. The sacs on these tubes (or lungs) push the air through and produce a unidirectional flow that gives the bird more oxygen than the reptile or mammal would have.
These sacs keep some depleted air in the lungs so they can be refilled with oxygen. This gives the birds a steady amount of oxygen, which results in the perfect flying ability these creatures have.
The lungs in reptiles, which dinosaurs are a part of, are very unlike birds, more like mammals.
One of the most famous features of the bird is its hollow bones. These bones allow for birds to weigh much less and put less strain on their muscles. The bones of dinosaurs, however, were strong and certainly not hollow. Unless these bones hollowed out and became very fragile, then the theropod couldn’t have evolved hollow bones.
Not only do hollow bones not work with dinosaurs but their tails are also a problem.
In theropod dinosaurs they had to balance their front weight with a long, heavy and well-designed tail. This tail was thick and would never allow for flight. Even though some birds have had bony tails, not one has ever had a tail nearly the size of a theropod’s!
The complete complexity and differences between dinosaurs and birds is beyond what has been described here. Dinosaurs and birds were completely different creatures and one could have never evolved into the other.
