We are often just TOLD this happens and that we can't see it because it takes an 'eternity'....it's a nonsense and luckily it is now being questioned seriously by serious thinkers.
I challenge you to detail for example the evolution of either bird lung or bird wing, without just saying this turned into that and that turned into this. Tell us how this takes could happen please!!! I want to know the mechanism.
The reptile lung, with its bidirectional air flow, could not have evolved into the bird lung with its unidirectional flow, because it is not possible for there to have been an intermediate model between them. In order for a creature to live, it has to keep breathing, and a reversal of the structure of its lungs with a change of design would inevitably end in death. According to evolution, this change must happen gradually over millions of years, whereas a creature whose lungs do not work will die within a few minutes. The passage from a terrestrial lung to an avian lung is impossible, because an intermediate form would serve no purpose. Reptiles have a diaphragm-type respiratory system, whereas birds have an abdominal air sac system instead of a diaphragm. These different structures also make any evolution between the two lung types impossible.
So, tell me how the the bird wing evolved. I'll start you off with the fact that the feather cannot function as an organ of flight until the hooks and barbules are coadapted to fit together perfectly. So go on, tell me more please......
Consider Exogenesis and stop sweeping issues under the carpet. |
Birds did not evolve from reptiles they evolved from dinosaurs and I do not believe that you have one to compare too? Feathers have been found on dinosaurs, they have even found one that could glide.

In a matter of speaking it is still the age of the dinosaurs as there are about 10,000 different species of birds.
They are tracing the evolution of DNA and the evolution of proteins, yet here you are hoping to deposit superstitious magic into this tree of evolution and then you say it makes more sense to have magic, all because your small mind can't grasp what 3 billion years looks like to life on this planet. This is what our ancestors did when they couldn't figure out how the little bright sky lights and the moon came to be...

Your evidence for this superstitious belief is 'It's to complicated' or ' there wasn't enough time." If species did not evolve from other species they must of popped out of thin air and you call evolution hard to believe, talk about weak, geez.
