Even in the definition you posted there was a definition, and then three paragraphs of refining. Your first paragraph contained the definition, two had additional explanation, the third explored the largely arbitrary micro/macro distinction- and if anyone would like to assert that there's any significant difference in the mechanisms of macro-evolution then they can present evidence that this is the case, like any other scientific claim- and the fourth corrected the "evolution= abiogenesis" misconception, and the common ancestry inference.

To characterize any of those as additional definitions is just absurd. I will, however, concede that my question could have been broader, to encompass those weird "micro, not macro" believers. Perhaps a third question: to what extent do you accept evolution, and why?

I disagree. I quoted TalkOrigins, which is a fairly well-respected site on evolution. IMO an article on TO carries more weight than the opinions of you or Exlax.

The piece said straight out that "The word evolution has a variety of meanings." If you just want to go with their first definition - Evolution is a change in the gene pool of a population over time - then I accept evolution. I fully accept that the gene pool of one generation is not an exact duplication of the generation before it.

According to TO, that includes some biologists: "Some biologists feel the mechanisms of macroevolution are different from those of microevolutionary change."

Quote:Perhaps a third question: to what extent do you accept evolution, and why?

As noted above, I accept the first definition, as it is demonstrable.

And as I said, if those biologists wish to propose a falsifiable hypothesis as to what those macro-mechanisms are, as well as how they're meaningfully different from micro ones, test that hypothesis, and show real evidence that they exist and how they work, then I will listen.

Until then, the distinction is a meaningless one made to prop up intractable creationists.

Quote:As noted above, I accept the first definition, as it is demonstrable.

Given that the "micro" definition is demonstrable, and sufficient to cause the "macro" changes, then I suppose you accept evolution in general.

I know what's coming, by the way; I just need to play my part.

Whatever - I didn't think this was about your beliefs. I don't really care if you believe differently from the biologists the TO article had in mind.

The term was coined by an evolutionist.

It's not a given that the micro definition is sufficient to cause macro changes.

Well then you would need to propose a mechanism by which those smaller changes are prevented from accumulating. Until then, the logical view is that small, demonstrable changes will build up, just as it's logical to consider that if I walk solidly in one direction without interruption, I will eventually have walked a mile.

I dare you to make a more vague statement.

First, you haven't proven that the small changes represent anything new.

By the first definition, which I accept, a simple example of evolution would be that one generation has 75% brown eye genes and 25% blue eye genes, but the next generation has 74% brown eye genes and 26% blue eye genes. There is nothing new in this form of evolution, and nothing to accumulate.

Second, you haven't proven that changes go solidly in one direction. Going back to my example, the third generation could have 75% brown eye genes and 25% blue eye genes. This would be evolution from the second generation, but it would have gone nowhere from the first generation.
