So then, you really don't know what you're talking about then - right. Bat wings function like hands. Were their wings covered in feathers, it would require a different configuration that would disallow them to function like hands. They hang upside down and use their wings to hold their young in tight to them. Birds do not do this. As Science stipulates that behavior is inherent. How would bird wings aid the inherent behavior of Bats. They would not. Which suggests the wing design for a purpose.
Birds and Bats aren't like trucks and lamborghinis.
Yes, they are. I'm sorry; but, they operate differently, live differently, etc. They have different functions just as cars and trucks have different functions though they both are vehicles and have four wheels. They are obviously not ink pens, buildings, vaults, etc from the list of men's creations. They are creations of a specific type - automobiles. Semis fit the class of automobile - engine, wheels, etc. You probably would prefer I just said "dump truck" or "pickup". The analogy stands. Bats have different type of wings because they are used for nesting purposes. Bats don't make nests. Birds do. Birds therefore don't require articulate wings which they can use for grasping their young. All they need do is sit on the nest and cover their young with their wings when they feel it necessary.
I didn't say bats don't make sense, I'm just pointing out that it doesn't make sense to take everything that works on birds and then try to re-invent it.
No, you're saying it doesn't make sense to you. But then you haven't shown that you're really thinking about it from a science standpoint and applying what is known. Rather, you appear to be ignorant of the subject - that or trying to avoid the truth of the subject in hopes that people who don't know any better will buy your argument..
This is good timing! I was *just* reading this article earlier today:
Science more creative and less 'true' than many believe, educator says
