Oh, okay. I thought you wanted something like a flying elephant or whale.
had a rather enormous wing span according to fossils,
Some did, some didn't. The biggest got up to 25-30 feet, but there's an extinct bird with a wingspan almost as wide, the Argentavis magnificens:
yet evolution doesn’t, over ga-jillions of years, account for other equally larger animals flyng such as pterodactyls did, why is that?
Dunno. Why should it?
It's not a matter of me wanting that...but rather wanting to know what limits all this, let alone makes it possible and it does bring up an interesting question, what is it that limits any animals from growing some wings and, regardless of size, from flying period?
Dunno. Why should it?
If it's all supposedly without intelligence, totally random, without design, without purpose, then it's more than fair to ask these questions, particularly when so many liberals DEMAND children be programmed into their cultish way of thinking; all too often to the point of suing others who dare ask these kinds of questions of them, (let alone offering a better explanation, ie. intelligent design/creationism, etc).
Why don't humans just sprout wings for instance? Right now I can think of several reasons why wings would be beneficial and advantageous...driving in and around Atlanta often has me wondering why I don't have the ability to fly over messes. We can design devices to do exactly that, with our God-given intelligence. So by playing by your own rules of no intelligence allowed, why don't we have wings by now?
If ALL life came from a single celled organism, and all this variety comes from a single common ancestor, some animals through natural selection developed the ability to fly while others did not.
Why?
And saying "we don't know yet" or "just wait" or "be patient for another ga-jillion years" is a total cop-out. (We've had enough ga-jillion years to see plenty of variety!) Particularly when squealing any other view outside evolution isn't "science".
What is it about so-called "natural selection" that ultimnately determines which animal eventually flies and which do not and why? And what is it exactly that determines the rate of this so-called natural selection process which allowed for instance bats to fly?
And it's not just a certain animal kingdom, phyla, etc...insects, mammals as well as birds can fly for instance, moreover some animals with wings can't fly, while others without wings, come real close (flying squirrels), etc.
Why is that?
