However, as you move north and you get longer, darker winters you run the risk of vitamin D deficiency and rickets. Rickets is quite a strong evolutionary driver. Women with bad rickets struggle to give birth so there's a powerful filter.
And it seemed to be bound up in adaptations for eating wheat.
Pale skin, and the associated vitamin D absorption, look likely to become widespread very quickly in northern Europe once the adaption arises because the impact on fitness is very strong. I suspect there is also a warfare advantage driven by small but significant population advantages in kin-groups - but that's me guessing.
And at some point, given our African origins, we (white people in northern Europe) must have started out with darker skin. That must have happened at some point in the past. So there would be a before and an after. It doesn't seem "woke" to realise that in a thing with a before and an after some thing will be before and some after.
