You take a dog from sunny warm SoCal and relocate him to the arctic, he will change (adapt). But he will never ever turn into a polar bear no matter how may billions of years pass by.

Evolution affects POPULATIONS, not individuals you bloody nitwit!
No, no, joelch2, you're telling it wrong; it goes like this: a baby polar bear goes up to his mom and says, "Mom, am I really a polar bear?"...
So close, yet so fucking far away. Of course he won't evolve into a polar bear. But if you take whole groups of milder clime dogs and place them in the arctic, provided they can survive long enough to reproduce, then, given a few million or billion years, they will produce a new species of dog, that is more adapted to the colder climate than their predecesor/ancestor was. And no, they will still not be polar bears. However, their fur might be similar, in that it's transluscent.
Edit: I know I probably spelt transluscent wrong, but I'm sick, and I've been drinking. :D

"Do these people willfully misunderstand evolution, or are they really this stupid?"
The answer rhymes with both.
He may not, but in the unlikely event that pups are conceived, one may be born with a slightly thicker coat, allowing it to have more energy and reproduce more. After a few billions years of natural selection you will have an animal that will survive well in the Arctic.
It still won't be a polar bear.
How's that for a simplistic approach to evolution? It's probably a bit skewed but whatever.
His future generations will adapt. If you did but know it, you have described the workings of evolution.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
