Global Admixture Analysis at K=6

December 31, 2013

This new study has one of the biggest global admixture analyses ever done (185 populations at 293,832 SNPs), but it's a little hard to view so I made a more user friendly version of one of the runs. I chose K=6 because it shows clearly the divisions and admixture between the six main racial groups: Capoid (red), Negroid (orange), Caucasoid (blue), Americoid (green), Mongoloid (yellow) and Australoid (purple). Click the image below to enlarge it and scroll down for examples of the racial types.

K=2 separates African from non-African populations.

K=3 reveals a West Eurasian ancestry component [Blue].

K=4 breaks the African component into an African hunter-gatherer ancestry maximized in Bushmen such as the Ju_hoan_North [Red] and an African farmer component maximized in the Yoruba [Orange].

K=5 breaks the ENA [eastern non-African] component down into one maximized in the Karitiana from the Americas [Green] and one maximized in the Ami from Taiwan [Yellow].

K=6 reveals a south Eurasian component maximized in Papuans [Purple], which is also represented in South Asians.

Yoruba (Nigeria)
Sardinian (Italy)

Ami (Taiwan)
Papuan (PNG)

How is the purple component Australoid if the Onge aren't shown to be full purple?

Racial Reality said...

Obviously because it's almost 100% in Australian Aborigines and Papuans.

Truthteller said...

So then, are the Onge around 40% mongoloid? Because I have not read that anywhere. Yet that's what K=6 shows.

Nice one. I am a bit negative about that Iranians are so pure caucasoids tho'

Mark Royer said...

Are the Ainu missing from the study, or did I just skip over them?

the study shows the different ethnics, not different races.

Varg said...

Sorry,but Papuan Austroloids probably are old Turkic Kypchaks.

Max said...

How about Austronesians? Do they appear at k = 7? I do not see Indonesians, Filipinos, Melanesians, Polynesians, Micronesians etc.

roberto quintas, there are as many ethnicities as there are countries. This study obviously shows racial i.e. genetic differences. Seems to me like you've got it precisely backwards - you'd probably say that the French and the Germans are two distinct races, but same white ethnicity. They are two distinct ethnicities, but same white race.
