I’m curious in how people evolved based on where they live, like, I heard that europeans in Europe 40,000 years ago had dark skin, but how did they become white, was it a slow process breeding with the lightest of the dark for thousands of years or was there some kind of mutation or whatever like with blue eyes, And I googled what causes mutations (cell division and replication errors) but I still don’t really know what that is or how it works.. I feel like there’s a big gap in my knowledge when it comes to evolution and biology as a whole and I really don’t know where to begin. like, at all.
