Nor does it seem that a multiplicit mutagenics that result in non-interbreeding related intergrade species strike a logical chord...
Nor do they ever acknowledge allopatric speciation, even though it is one of the most easily understood - and demonstrated - speciation events. Heck, it’s how Darwin came to put all the pieces of his theory together.
Of course, “They’re still finches/birds!” they will cry. True, but when, over time, those finches no longer interbreed for a variety of reasons - BEYOND geographic barriers, they’ve become distinct species.
Within an hour or so, I would think even the most ardent creationist would accept that. That’s when we’ll hear about “kinds” and such. But it’s a step I guess.
