It's never going to happen. Nor will you get a clear definition of the cutoff between what is called microevolution and macroevolution. Creationist arguments need to be vague so that they cannot be disagreed with.
Yep, and they accrue over time into larger changes. There is nothing known that can prevent it.
Proof is irrelevant.
Furthermore, there is no burden of proof (or burden to provide compelling evidence) when dealing with a person who decides what is true about the world by faith rather than by the valid application of reason to the relevant evidence. It's simply not possible to convince another person of that which they have a stake in not believing. Teaching in the academic style, which is distinct from indoctrination, requires certain skills and dispositions in the student. It's a cooperative effort when it occurs. The faith-based thinker is not going to cooperate. He will resist.
Irrelevant to the theory of biological evolution, which not only makes no claim that such a thing could happen, but implies that it cannot. Change is always gradual, and offspring resemble their parents, but not necessarily their great-great-great ... great-grandparents.
If we go back enough generations, our ancestors would be marine forms with fins, gills, and scales. Further back, some form of invertebrate worm. Each of these had offspring closely resembling themselves, but a little different. Over deep time and separated by millions of generations, the descendants look a lot different than their distant ancestors.
- "Natural selection is an anti-chance process, which gradually builds up complexity, step by tiny step. The end product of this ratcheting process is an eye, or a heart, or a brain - a device whose improbable complexity is utterly baffling until you spot the gentle ramp that leads up to it. " - Dawkins
Irrelevant again.
If you want to critique the theory, don't you think that you should learn what it says rather than rebutting straw men? What chance do you have to be convincing if you make irrelevant claims such as a lack of proof, or that existing forms don't transform into one another across a generation?
And please explain why we would trade in a useful scientific theory that has already improved the human condition for an idea like creationism that has no practical application even if correct?
I am aware of what the theory says, the theory I critique.
I've said elsewhere that most scholars take the biblical "kind" as what taxonomists call "family". Here, you, me and the Bible agree. A mating pair or single reproducing species will not birth a different family of animal or plant, in one single generation.
The problem we're having, though, is grand generalizations, which we Christians note are just-so stories, like this statement you made:
"If we go back enough generations, our ancestors would be marine forms with fins, gills, and scales."
...Are you saying scientists agree as to the progenitors of apes? You are filling in "Science isn't sure, yet" with your EvolutionDidIt... that shows a spiritual or religious fervor not demanded by the science or rationality.
