Atheistoclast wrote:... Evolutionists believe the hindlimbs of cetaceans were heavily reduced through degenerative mutations. OK. That is a reasonable point. Mutations can cause developmental arrest of parts. But the problem is in explaining the origin of the complex marine adaptations that also require need to be coordinated with each other to a large degree.

It is just not annotated.

If evolution is the result of the natural selection of random mutations in DNA, can someone please tell me how such an anatomy entirely suited to a marine environment and replete with blowholes, flukes, dorsal fins, flippers etc could have evolved through molecular tinkering in the DNA? I do realize that the dolphin genome is not yet available. But still.
Don't just say Evolutiondidit.
What's that part labelled 'pelvis', Atheistoclast?![]()

No response, unsurprisingly!

I propose we conduct an experiment and see if a race of mermen evolve.
But evolution is false, so we might not even bother.
How long do you think such an experiment would need to run, atheistoclast?
This was the exact question I was going to ask. I'm interested in what his response is, so I hope he does reply.

Yes. That's one dolphin species, not "The Dolphin".

Firstly; What is an Evolutionist?

That pelvic girdle just ain't quite the same as a pelvis, is it Atheistoclast? I know it's all so confusing that it uses a similar word and stuff...

Thats a funny last line. Never saw it before.
I am a YEC and agree selection on mutation plus time is impossible and unreasonable even for the origin of this creature.
YEt i strongly agree and welcome its just a adapted creature to a post flood world. It was on the ark as a land creature and by innate mechanisms instantly adapted to the seas. nO intermediates but there would be variety's.
Biological change is real and so mechanisms are there.
Even if we have not been smart enough to figure them out.
