Actually science forgot about all of these in their theories, Darwin was concerned.i think you are seeing what you want to see.
then you have to ask yourself, why would god create all these (millions of them) closely related species? to me this seems like something occurring in nature and fairly random.
Science is proud to show all of the similarities, in whales for example show differences but gradual placement of fins etc. But if you are going to create a million animals, and these are to fit certain places in the food chain, why not make a DNA sequence and be able to manipulate as you like. Very much like computer code.
The other big question about this is, why does all the changes been made from evolution stop at completed animals, why does it not continue on. So we should be seeing bit's of new kinds of legs for instance or unknown part parts, in this trial and error that evolution would do. Evolution doesn't know it should stop doing this. But we don't see this either. If evolution was correct we should be see all sorts of horrendous animals in all states of change, in the world right now.
One other thing is that when, a system for a leg for example, you need heart, lungs, kidneys , veins, nerves, blood, and all connected to the brain. What came first, in this system? You need the whole system at the same time for any of it to be useful. And how did evolution know what was needed to make working legs? Not only but the bones have to fit other bones, but not touch each other, but use other tissue to connect all of this. When your done it is not just some, awkward leg , it could be the legs of a cat. How did the brain get all the gaits of movement for the animals so that eyes , muscles, brain can move like that of a cat.? Science can't demonstrate this even in a lab.
The reason we don't see any of this is that it is impossible. Without creation to make it correct in the first place, there would not be anything.
