Yes, very strange, since they (animals) have developed very differently and you can't say they've "degenerated". That term means nothing.
Are smaller animals degenerates of the larger ones ? Are the red kangaroos degenerate because they've changed colour ?
Your term means nothing.
You are just saying things that come to mind, but with nothing to back it up.
On top of this, your are philosophising ! You said you wanted facts. Nowhere in the bible does it say animals can "degenerate", whatever that even means.
Can you please stick to facts as you said. Or should I quote you again.
This is very misleading. There will always be missing links. Let me explain:
Let's say we have in our "evolution line" that goes from 1-10 (1 being the furthest back we can go and 10 being now)
We have examples from 3-6 and 7.5-9 and then 9.5-10.
Let's say we find the missing link 7, you will say no evidence was found for 6.1-6.9. Let's say we find evidence for 6.1-6.9, you'll say we have no evidence from 6.01-6.09.
Let us say we find evidence for 6.091-6.100, you'll say we have no evidence for 6.0901-6.0909.
And so on.
A very simple story someone once told me demonstrates the idea though.
Let us say a bank was robbed. You are the jury. The defendant is seen on camera entering the bank at night, entering the manager's room, taking the key to the safe, opening the safe, the camera in the safe is turned off during the robbery, then the camera just outside the safe is also off, the next camera to pick him up is in the main bank reception with a bag that seems full on his shoulder, then coming out of the bank with the bag.
So basically, you're missing the robber taking the money, but money is missing from the safe and you know he was in the bank. Your "missing link" is one piece out of a massive puzzle.
Are you going to convict the defendant? Or are you going to say he's not guilty ?
Most people would convict him and they would most likely be right. Of course there's a chance they were wrong and the guy only went in to get his stuff from the safe while someone else robbed the bank that night. Or God could have robbed the bank himself, but the more likely explanation is that it's the defendant.
So you see the missing link is not a really good argument, because the point is that evidence for evolution is massively overwhelming.
