I realised that for some reason, I still don’t know this. Why do we have different skin colors, hair textures, eyes or such? Is it just a random thing that happened or are there evolutionary reasons to it?

    Put differently (so as not to imply high melanin is fundamentally superior):

    Someone mutated to have lower melanin levels in their skin, which was useful to absorb more sunlight for Vitamin D production further north, and that mutation spread.
