And yes, I've heard all the darwinist fairy-tales [just-so stories] about how, once upon a time, these creatures did not live in snowy climates, until one happy day a normal brown animal suddenly was touched by a magic genetic mutation that caused white fur when the winter came, but reversed itself with the snow-melt, and that complex but fortuitous genetic mutation enabled/compelled him/her to move north in the winter for camouflage purposes--to a place where, previously, all the brown-furred animals were wiped out soon after the first fall of snow, because they weren't snow white. Duh!!
You have not, in fact, heard that, because no-one has ever said that.
Except possibly the voices in your head.
Does gravity change "in unpredictable and irregular ways"? Does electro-magnetism or the nuclear forces?
No, but environments do. This is a fact.
So how in the world can darwinists keep insisting that their "NS" is on the exact same level of causality as the four accepted 'forces'?
They do not, which is why you can't quote them as doing so.

Why don't you try arguing with some opinion that someone actually holds? Or is that too difficult for you?
