Fallacy of Evolutionary thinking

In my experience, evolutionists fixate only on the supposed evidence for their theory, not on the impossibilities. With any scientific hypothesis, there will always be reasons to believe it. The scientific method requires that one objectivly and critically analyze the negative arguments. Instead, evolutionists are so entrenched in their dogma that they simple sweep hostile evidence under the rug.
For example, Let's discuss the evolution of flight in bats. How could the gradual elongation of phylanges to form wings have been any sort of selective advantage in early stages of evolution? They would have been a hindrance and would have been selected out. I would point out that flight has "evolved" indpendly in nature at least four times... in mammals, birds, reptiles, and insects. No satisfactory explanation for the evolution of flight has ever been put forth, let alone any evidence documented in the fossil record.
In response to this and innumerable other questions I've raised, I usually get the explanation that all the "details" haven't as yet been worked out.
One more question... How did Hemoglobin gradually evolve?

nor is it a shortcut to bypass the PNT.Closing thread.
