Show me one mutation that could turn a snake into a whale over any number of years? Show me a mutation that can reproduce to identical bilateral flippers on an organsim? Unless you think all the one flippered whales died out, just happend to never fossilize.

Bilateral symmetry evolved first, stupid.
If a snake turned into a whale, that would be a falsification of evolution, stupid.
The tree of life branches, stupid.
I'm just going to keep calling you stupid, stupid.
Maybe some of these people (like Croissanwich, here) should crack a book every once in a while. I think its hilarious (yet terrifying) that people entirely ignorant of something as complex as evolutionary genetics and development feel pretty free throwing around ideas like this. It may just be a hunch, but I don't imagine that Croissanwich is a geneticist.
Think about it, C-man. What would you think about someone who knew nothing about your line of work, and yet continually spouted off about how pizzas were made?
It gets even stupider:
"Actually unforunately for evolution. Because the modern day horse in that example, does not have the genetic coding for the cat, its ancestor.
"So now not only does evolution have to explain how the DNA of a horse got into a cat, but how the DNA of the cat was lost when it became a horse.
...
"We're talking about micro-adaptation that is the supposed cause of evolution. Micro-adaptation causes no change in DNA. Which is required for evolution."
Hey Criostard, just saying so doesn't make it true.
Umm, hey asshole. I actually literally can show you a mutation that can produce identical bilateral flippers on an organism. The genes involved are: Sonic hedgehog, fibroblast growth factors 4 and 8, and Wnt7a, between the three of them they instruct an embryo to turn on the genes that cause limbs, and are responsible for bilateral symmetry. This is what happens when you argue with a professional.
Perhaps the mutation that likes to make things symmetrical? As most species have it, I guess it came VERY early in the evolutionary tree.
And no, the cat is not the horse's ancestor. Somewhere on the tree there is a common ancestor, surely, but as both cat and horse are living today and show recent evolutionary changes, neither is the ancestor of the other.
In immortal words of Academician Prokor Zakharov from Sid Meier's Alpha Cenauri, genes are NOT blueprints. This means you can't, for example, insert "the genes for whale's flippers" into a snake and get a snake with flippers. There are no genes for flippers. What you CAN do with genes is chemistry, since DNA codes for chemicals.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
