If the above is true, why didn't it affect Eskimos, Lapps and indigenous Siberian peoples the same way.

Light colored eyes let in more light to see in darkness

Pre-industrial darkness was the same all over.

Because that's not how evolution works. Traits don't magically appear because they're logically advantageous.

Random mutations occur and it's up to chance whether they're useful or not. Most don't even make it out of the womb.

My questions is why these random mutations for light hair and eyes DID NOT show up in other races?

The Canadian tribes have light skin compared to the US tribes. If the gene for light eyes and hair had manifest in the mongoloid people, it would've been an advantage.

Africa and the mediterranian had more sunlight near the equator.

All North American Indians are lighter skinned now, but this is due to the contribution of European genes.

No it is not. It's dark for like 6 months out of the year when you go far enough north, I'm talking 24 hours a day

By that line of reasoning, the Inuit and Yupiks should be whiter and more varied than Europeans, since those are the people that lived in the areas you describe. Still nothing to explain white skin and blue eyes based on sun light duration.

Apparently they started off Asian, and are on the way to lightening. They have the same eyelid fold as the Asians.
