If it doesn't literally know anything, how does it know how to select in a natural manner?
Do dice know anything when you roll them?
Try this: Roll a dozen dice. A couple of them will most likely come up sixes. Keep those and take all the rest and roll them again. Maybe a couple more sixes, eh? Do this until you have all sixes.
How do the dice know? How do they know???
Now, do the same thing with any living organism and kill off all of the population with a specific trait. Assuming you aren't killing them all off, in a few hundred thousand, or a million years, what do you expect you'll find?
Again, how do they know???

The point I made is that mutating genes have no idea what environment they are in so why should any mutation be favourable to the environmental context? (This was the gist of the original post in this thread)
Of course the mutating genes have no idea of what they "should" be doing.
Gene mutations are just accidents, some simple and some more complex. And some happen to be better suited for the current environments, while others are deleterious.
So, guess which ones are more likely to be passed down to descendants?
And in the case polar bears and other white animals that are camouflaged their genes are totally unaware they are living in a white environment. For a gene to create such a specific, valuable, environment-matching adaptation is indeed rather like magic. And was this alleged transition series observed or is it speculated out of necessity because the theory demands it?
Again, gene mutations are accidents. But the individuals who inherit those genes may be more, or less, suited to a particular environment and this has a direct bearing on whether they pass those genes on.
Within most organisms (or rather populations) there is quite a range of variation. Some are better adapted, others not so. If the environment changes, the ones who are better adapted might no longer be so, while others might suddenly become better adapted.
No magic needed.
Here is an on-line lecture that helps to explain how things can evolve naturally:
Making Genetic Networks Operate Robustly: Unintelligent Non-design Suffices, by Professor Garrett Odell (online lecture):
Abstract: Mathematical computer models of two ancient and famous genetic networks act early in embryos of many different species to determine the body plan. Models revealed these networks to be astonishingly robust, despite their 'unintelligent design.' This examines the use of mathematical models to shed light on how biological, pattern-forming gene networks operate and how thoughtless, haphazard, non-design produces networks whose robustness seems inspired, begging the question what else unintelligent non-design might be capable of.
