I’m amazed when genes turn on and off. What a concept.
Not sure what your are saying. Most Scientific research that has studies migrations indicate that humans moved out of eastern Africa to Europe and Eurasia about 60,000 years ago, most probably from Ethiopa which as the oldest humo sapiens fossils and predate 60,000 years ago.The fact that this early human in Britain 10,000 years ago looked like he did. Why does that freak out people Skin color changes. How many blondes do you see going to tanning booths result in a different skin tone, and that is within months.
I remember when Otzi the Iceman was found in the Northern Italian alps (he is about 5,000 years old), there were lots of folks bantering about what he looked like. On hte fringe right, The Nordic-Aryan supremacist types were saying he was likely a blonde haired fair skinned Scandinavian-german type. The marxist Afro-centrist were predicting he would be a black sub-saharan looking African he had migrated that far north.
It turns out he had brown-blackish hair, brown eyes and olive-white skin and his DNA correlated closely to modern Southern European populations (Italians and Greeks), most closely with Southern Italians, and among them the Sardinians.
So if you go back 5,000 years further than Otzi, this early British chap having darker skin and blue eyes could reflect someone whose ancestors settled thousands of years before and the colder climate produced at some point in time a recessive gene (blue eyes) and over time being in colder climate, skin tone gradually evolved to what you find common in England today.
The only people who will get pissed off at this are the Neo-Nazi types.
