Adaptation is change to more optimally exploit a situation, and can occur over very long periods of time.
I think I did - ring species. You still haven't tried to rebut that argument, so, unsurprisingly, I still consider it a correct answer. If I considered it correct then, why wouldn't I now still? I've explained what can change my mind and what can't. Only rebuttal, which is a very specific type of argument - one that falsifies a claim. Merely disagreeing and explaining what you believe instead accomplishes nothing. You'd need to give me a reason to think I'm wrong, and only a sound, falsifying argument can do that. Nothing else. Please look at that again: NOTHING ELSE. If your purpose is only to share your ideas, then you don't need to worry about how they're received. But if your purpose is to change critically thinking minds, you'll need to learn what can and what cannot do that.
Because that true. There was no human being born that didn't have human parents. But this opens the door to the
sorites paradox that occurs with gradual transformations from one thing to another. There was no first human being, yet human beings didn't exist ten million years ago but do now.
No. That's a semantic quibble based in my not specifying being fertile.
So you claim.
No, based on their fecundity. Surviving isn't enough, which is why I call survival of the fittest an unfortunate choice of language. Proliferation of the most fecund is more descriptive.
So you say. You know the drill. Demonstrate the circularity if you can, and if you're correct, you can. If you're wrong, you can't.
Darwin claimed they evolve.
Do you mean naturally gentle, or tamed by man? Darwin's theory only addresses the former. Either way, nothing about wolves contradicts Darwin. If you want to do more than tell others your opinion, you need to do more than merely state it.
Did I claim that? What I said was that niche is not part of the concept of species, and I gave the ring species example how speciation can occur in a niche. I assume that you didn't accept that argument, but since you didn't falsify it, it remains my position. You can't make progress without dialectic, and it's not dialectic without rebuttal/counterargument/falsification (synonyms in this context). Separate lions in a single niche into two populations unable to interbreed, and eventually, you will two species of lion.
