The Englishmen with African Y-DNA

The Englishmen with African Y-DNA
https://www.dailymail.co.uk/news/article-431948/Yorkshireman-share-DNA-African-tribes.html Quoting:
John Revis has always considered himself a true Yorkshireman who was proud of his ancestry. But he has been forced to confront an entirely different heritage - after scientists uncovered that he has exactly the same DNA imprint as a tribe of African warriors.
Scientists last week announced the discovery of the first proof that slaves brought to Britain by the Romans left behind a distinct genetic heritage. This strand was revealed to exist among just seven men with a particular surname hailing from the North of England. However, the academics refused to disclose the identities of any of those men included in the study. Now The Mail on Sunday has discovered that all of those with the African lineage have the surname Revis . . .
Scientists from Leicester University made the finding during research sponsored by The Wellcome Trust. They were examining the relationship between the male, or Y, chromosome and surnames. Like surnames, the Y-chromosome is passed from father to son, virtually unchanged through generations.
Professor Mark Jobling said: "We found John was in the A1 group of Y-chromosomes, which is very rare and highly west African-specific. This study has shown what it means to be British is complicated and always has been. Human migration history is very complex, particularly for an island nation such as ours. This study further debunks the idea that there are simple and distinct populations or races."
Over time, the Y-chromosome accumulates small changes in DNA sequence, allowing scientists to study the relationships between different male lineages. The surname Revis is believed to derive from Rievaulx Abbey in Yorkshire.
Fellow researcher Turi King said: "Our findings represent the first genetic evidence of Africans among 'indigenous' British people." She added that Africans were first recorded in northern England 1,800 years ago, brought by the Romans to help defend Hadrian's Wall. Ms King said: "The slave trade was responsible for the influx of Africans in the 16th and 17th Centuries. By the last third of the 18th Century there were 10,000 black people in Britain.
Previous studies of British genetic diversity had found no evidence of African Y-chromosome lineages."
WIKIPEDIA:
The subclade A1a (M31) has been found in approximately 2.8% (8/282) of a pool of seven samples of various ethnic groups in Guinea-Bissau, especially among the Papel-Manjaco-Mancanha (5/64 = 7.8%). In an earlier study published in 2003, Gonçalves et al. have reported finding A1a-M31 in 5.1% (14/276) of a sample from Guinea-Bissau and in 0.5% (1/201) of a pair of samples from Cabo Verde. The authors of another study have reported finding haplogroup A1a-M31 in 5% (2/39) of a sample of Mandinka from Senegambia and 2% (1/55) of a sample of Dogon from Mali. Haplogroup A1a-M31 also has been found in 3% (2/64) of a sample of Berbers from Morocco and 2.3% (1/44) of a sample of unspecified ethnic affiliation from Mali.
In 2007, seven men from Yorkshire, England sharing the unusual surname Revis were identified as being from the A1a (M31) subclade. It was discovered that these men had a common male-line ancestor from the 18th century, but no previous information about African ancestry was known.

Re: The Englishmen with African Y-DNA
This study further debunks the idea that there are simple and distinct populations or races. :lol:
No it doesn't.
Anyway, that is interesting. But having a particular haplo doesn't change your "race." I got my Euro m. haplo from my black great-great grandmother.

Re: The Englishmen with African Y-DNA
I would agree that haplogroups are too ancient to be definers of race. My maternal haplogroup, H5, originated in West Asia but it also has some concentration in Wales.

Since it comes from West Asia and it is concentrated in Wales, do you think it is a Roman holdover like the article's example?

That's for H5 in general, which seems to be from the Neolithic. I'd forgotten, but mine is specifically H5a1. Wikipedia:
"The subclade H5a1 . . . appears to occur fairly evenly across Europe at slightly lower levels than its parent. The population average in samples from Austria, Germany, Hungary, Macedonia and Romania was 1.8%. In a very large sample of the population of the Austrian Tyrol, H5a1 was found in 2%, whereas H5a was found at 2.9%."
