Would you care to explain to us how this takes place? 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.
