I am assuming that it takes a very long time, with a number of incremental changes that have to not only survive, but fit together in a systematic, calibrated way.
Yep. That's what evolution is. And the end result will look systematic, because it's worked. The failures are dead.
Have you ever noticed how the earliest birds had less effective wings and feathering than the modern ones? Or toothed beaks? Or bone structure not so advantageous for flight? And, indeed, there's debate over whether some are truly birds, or reptiles? And then, as the fossils get newer, they lose the teeth, and true sternums appear, and the wing bracing structure looks more like that of modern birds...
Or do you hold that fossils are little fakes created by the devil, or millions of deluded scientists, or indeed traps from the god Loki?
In fact, what do you believe fossils are?? |
