People who understand evolution.
Scientists are emotional human beings who carry with them a generous dose of subjectivity into the supposedly objective search for truth.
Doesn’t change their research or the information discovered from them.
No convincing transitional forms have been found to fill the gap between creatures that can fly and those that cannot.
When your mind is closed to other possibilities, not even God himself can provide something that is convincing. Your unwillingness to see what is right before you doesn’t change reality.
Appearing ABRUPTLY in the fossil record with complete , fully functional wings are birds, bats, flying reptiles and flying insects.
Why do you capitalize abruptly like it is important? Oh…that’s right, you don’t understand evolution, so you remain under the delusion that abrupt appearance is somehow a problem.
Archaeopteryx had wings claws and teeth.
Not entirely. Some would argue that it didn’t have wings, as it could not flap them and actually fly, but only glide.
Some reptiles have teeth and some do not.
And? You are oversimplifying things to about 5 powers of ten. The fact that some reptiles do not have teeth is quite irrelevant, especially since archaeopteryx came from dinosaurs, which were not reptiles, and became birds, which are also not reptiles. The comparison is utterly pointless.
Some fossil birds had teeth, some did not.
Which ones didn’t have teeth? And just so we’re clear, I ask this only out of curiosity. It doesn’t really change things.
Claws are not distinguishing either.
Once again, a gigantic oversimplification of things. Technically, people have claws too - that’s what finger nails are. How is this relevant?
Some living birds have them such as the ostrich, the touraco and the hoatzin. There is no question that these are 100% birds.
This is also quite irrelevant.
Importantly, this creature had feathers. The feather impressions revealed them to be fully functional.
Fully functional in what regard? Feathers insulate, they assist in gliding, in flight, in keeping water out, and multiple other things. You need to elaborate on what you mean by fully functional.
There is no evidence of reptilian scales developing into feathers. No animal except a bird has ever been known to have feathers.
Yes, yes there is. There are piles of papers and books on the subject. At least look for something before you claim it doesn’t exist.
