Firstly: triple-post = PHAIL. It's annoying. edit: oh, look, quadruple post. I was ninja'd x3. D:
Now that that's out of the way...
Allright there are actually 6 types of evolution.
Source, and additional information please. I've never heard of this.
Macro evolution is one kind changing to another, like a banana tree changing into a fly. This has never been seen, and neer been proven, and so far is mythical.
Again; just like gravity "has never been proven."
We do, however, have a plethora of evidence.
As for a good mutation, no, there are NEVER any 'good' mutations. Also with a mutation, for evolution to succeed you would need a new input, a new addition to an organisms DNA, and this has never been seen ever.
... w... t... f are you talking about?
"Good mutation;" see what I said about microorganisms and natural selection against our methods of killing them.
We've been able to study DNA well enough to know beyond no reasonable doubt that it
does vary to some degree, randomly, during replication etc.
Further, DNA is code. You do not need "more" DNA to create a new structure. It's like programming. You can have two pieces of software that are the exact same length, in source code, but perform completely, absolutely different things.
As for proving gravity, well the gravity IS a theory. But! You can actually test gravity and gravity is able to be tested anytime. As with evolution, you can never 'test' evolution, and therefore it hardly qualifies as a theory.
Microevolution is, again, beyond reasonable doubt. And when you change something enough, it no longer resembles its original form.
None.
