Diana's mtDNA ancestor "Eliza" was a native of Mumbai

"Appointed a Woman of the Bedchamber to Queen Elizabeth the Queen Mother in 1956, Ruth functioned in a world where breeding and good behavior were all-important. While she could adopt the latter, there was no way she could invent the former. Her family was neither grand nor impressive. In fact, the only thing that put them beyond the ordinary was the secret they kept hidden. This was that her great-great grandmother Eliza Kewark was a dark-skinned native of Bombay who had lived, without benefit of matrimony, with her great-great-grandfather Theodore Forbes while he worked for the East India Company. Unsavory as the taint of illegitimacy was, even at that distance in time, it was nothing compared with the stigma of what was then known as "colored blood." Had it been generally known that Ruth and her children were part-Indian, they might never have made good marriages. Eliza's true race was therefore expunged from the family tree and she reemerged as an Armenian. This fiction was maintained even when Diana married the Prince of Wales."

Visst finns det genetiska skillnader mellan olika folkgrupper idag:

Everyone living outside of Africa today has a small amount of Neanderthal in them, carried as a living relic of these ancient encounters. A team of scientists comparing the full genomes of the two species concluded that most Europeans and Asians have between 1 to 4 percent Neanderthal DNA. Indigenous sub-Saharan Africans have no Neanderthal DNA because their ancestors did not migrate through Eurasia.

Människans och schimpansens DNA sekvens är identisk till cirka 98.5 procent men nu visar Uppsalaforskare att delar av arvsmassan saknas helt i den ena eller andra arten. Det medför i vissa fall att människan kan tillverka ett protein som schimpansen saknar och vice versa. I studien, som publiceras i novembernumret av tidskriften Journal of Molecular Evolution, uppskattas den totala variationen mellan människa och schimpans istället till 6-7 procent.
