Scientists simply do not have good data on the genetic characteristics of particular countries in, say, East Africa or East Asia. But pinpointing a particular country of origin, as many testing services claim to do, is far trickier. Genetics researchers generally know which DNA sequences originated on which continents. The question of ethnicity is enmeshed with another difficult challenge for DNA testers: geography. If testing "tells me I'm 95 per cent Ashkenazi Jewish and 5 per cent Korean, is that really different from 100 per cent Ashkenazi Jewish and zero per cent Korean?" wondered Jonathan Marks, an anthropology professor at the University of North Carolina at Charlotte, in The Wirecutter. As a result, they share tell-tale sequences of DNA, easily identified by testing.īut is this sort of ethnic categorisation really instructive? Humans share more than 99.9 per cent of their DNA what makes us different is vanishingly insignificant in terms of genetics. For school and office work and things like spreadsheets and video editing, there’s no good. Historically, Jewish populations were small and tended not to marry outsiders. Your guide Wirecutter Staff Smartphones and tablets may have taken over much of people’s screen time, but there’s still a need for a real computer sometimes and for most people, that means a laptop. Jewish ancestry, on the other hand, is far easier to discern. As a group, their DNA was 6.2 per cent African, 18 per cent Native American and 65.1 per cent European.
Hispanics living in the South tended to have more African ancestry. We’ve gathered some of our picks that have.
Some had no Native American ancestry others had 50 per cent or more. The Wirecutter The Best Cameras and Gear for Beginner Photographers Finding the right camera can be hard for a photographer of any level. The ancestry of those who said they were Hispanic was something of a hodgepodge. Experts say the large proportion of European DNA found in African-Americans can be traced to before the Civil War, and the rape of enslaved African women. The chances of having African ancestry were highest in the South, and highest of all in South Carolina, where at least 13 per cent of those who said they were white had African ancestors.Īmong those who said they were black, genetic ancestry overall was 73.2 per cent African, 0.8 per cent Native American and 24 per cent European.
