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?

    I think the impact of wealth and access to nutrition and an environment that does not stunt development plays a major role here as well. A good example of this is height in Europe post-industrial revolution and improvements in medicine:

    Most notable being a 20cm increase in the Netherlands in just over 100 years as well as changes in places that industrialised quickly like China:

    Not to say that geography plays no role but it’s closer to 10cm gap than a 30cm one.
