First Britons were black

Bluebelle Loved your comment, made me giggle. Britain, is completely made up of so many, many immigrant groups. Wave upon wave of such groups over thousands of years.

This needs teaching in every school It might shut some of the racists up
It’s been known a long time that the origin of humans was in Africa so it doesn’t take too much of a leap to believe the first Brits were black
Oh I d love to see that English lady s (is lady in context here) face when told she is a by-product ???

I believe there is a living person in the South of England who is a proven descendant of Cheddar Man. Perhaps he should have a word with Jean.

I'm reading a book called "Who we are and how we got here" by David Reich. His speciality is Ancient DNA and he suggests the same thing, except he thinks that a new wave of people replaced the original darker skinned people. The new wave of people could have come from Sardinia, but a lot of research still needs to be done. People with lighter skin would have survived better than darker skinned people (as you say) because they would have absorbed more Vitamin D. Reich thinks that very few northern Europeans are directly descended from the first settlers.

The evidence as I understand it is that lighter skin mutations developed relatively recently.

A paper I read about maybe five or six years ago explained how pale skin and lactose tolerance developed hand-in-hand (through gene mutation) as early peoples spread into northern Europe. It said this was probably making it possible to get enough vitamins D.

Here's a link to Science Magazine - (I think this is basically saying the same thing) Not sure if it's referencing the exact presentation I read about but it does explain the same info:
