I'm not trying to prove it. I'm saying: "Look, here's two different kinds with which you could easily get from one to the other with some microevolutionary changes." Don't you think that's possible?

Actually, no.

For a start, the emu is an endotherm- it's warm blooded. That means all of its cells have to gain many times more mitochondria than the dinosaur, and then they all have to be serviced by a fine network of blood capillaries that the dinosaur doesn't have.

Oh, and while it's evolving these features (for no apparent reason) it's got to find ten times as much food to burn and maintain it's body temperature. Oh, and if it wants feathers, it's going to have to grow hair first (hair and feathers both come from follicles). Tough to do when you're covered in scales.

A baby lobster and a scorpion look pretty similar, CS. Don't be fooled...

Re: Why do you keep comparing like kinds?
I suspect that under the hood (DNA, etc) they're quite dissimilar.

Actually, Meldinor, probably not.

Did you know that if you compare human, cow and kangaroo DNA, humans and kangaroos are most similar? This is despite the fact that humans and cows are fellow mammals, and the kangaroo is a marsupial.

It seems that similarities in DNA have more to do with morphological similarity than (supposed) evolutionary relatedness.

That, and it put a freakin' man on the moon... yeah, deep shizzles science is in

CS, we didn't put man on the moon through a sequence of unsound logical silogisms. (Though having recently watched a documentary entitled "The true story of Apollo 11", maybe you could be forgiven for believing that!)
