A Mind Forever Voyaging
This is interesting - it's certainly in line with the "culture as coexistence" theory that Justin posted.
New research has found genetic evidence that people of African origin have been living in Britain for centuries and many of their descendants are unaware of their African ancestry.
The research was published by the medical charity, The Welcome Trust.
The result came as a surprise to researchers carrying out a general study on the Y chromosome.
They found that a white man with a rare Yorkshire surname had a type of Y chromosome thought to be unique among people of West African origin.
Genetic dating techniques suggested that his African ancestor was in the United Kingdom 250 years ago.
A follow-up study of people with the same surname, which has not been revealed for ethical reasons, found that one third had the same African variation.
This backs historical data that records Africans in the UK centuries ago - some as Roman soldiers defending Hadrian's wall.
Turi King from the Welcome Trust says nearly half the people in the study had the African Y chromosome.
"I just happened to find this in one particular surname, with one individual to start with, and then I started recruiting other people with the surname and found that there are eight of them within the 18 that I managed to recruit with the surname that actually have this African Y chromosome."
