Aren't mutations supposed to be RANDOM? But you think this one just handily showed up when needed?
Yes, mutations are random. Discovering this mutation from, I believe it said 1 million years ago, tells us nothing about the multitude of other mutations that would have happened, but that were deleterious and caused the mouse that got said mutation to fail to procreate. This is how it works, it is not a single mutation that arrived just when it was needed.
Rather, it was a bunch of different mutations, one of which (Dark fur) happened to be advantageous in the enviroment that the animal lived in. This allowed the mouse with the dark fur mutation to propagate and this mutation begins to move toward fixation.

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity. - Richard Dawkins
Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night. - Issac Asimov
If you removed all the arteries, veins, & capillaries from a person’s body, and tied them end-to-endthe person will die. - Neil Degrasse Tyson
What would Buddha do? Nothing! What does the Buddhist terrorist do? Goes into the middle of the street, takes the gas, *pfft*, Self-Barbecue. The Christian and the Muslim on either side are yelling, "What the Fuck are you doing?" The Buddhist says, "Making you deal with your shit. - Robin Williams
