Pre-Columbian & Modern Native Americans in Eurogenes K36

[Peterski]

1) Pre-Columbian samples:

















2) Modern Native Americans:

I also found modern Mayans scoring few percent of "Malayan" admixture.

The same "Malayan" admixture was present in two Botocudos (Bot15 & 17).

Some explanations from Davidski regarding admixtures in Eurogenes K36:

An important point to keep in mind is not to take the ancestry proportions in Eurogenes K36 too literally. If you're, say, English, and you get an Iberian score of 12% this doesn't actually mean you have recent ancestry from Spain or Portugal. What it means is that 12% of your alleles look typical of the reference samples classified as Iberian, and this figure might only indicate recent Iberian admixture if it's clearly higher than those of other English users. But it calculates deep root similarities more than real recent ancestry.

So I wonder why is Kennewick Man scoring European & African admixtures?

Those Botocudos were Polynesians (who are a mix of Taiwanese, South-East Asian and Oceanian):

"Identification of Polynesian mtDNA in remains of Botocudo Amerindians from Brazil":

http://www.pnas.org/content/110/16/6465.full

Moreover, they were fully Polynesian (not mixed with Amerindians, Europeans, or Africans):

The second interesting aspect of the genomic sequencing is that the remains did not show any evidence of admixture with European, Native American nor African individuals. More than 97% of their genome fits exactly with the Polynesian motifs. In other words, they appear to be first generation Polynesians. They carry Polynesian mitochondrial, Y and autosomal (nuclear) DNA, exclusively.

Recent DNA has shown trading based out of Polynesia extended as far as South America and the Caribbean, but there have been questions to the exact timing. European traders are often thought to have led the spread of commerce across the globe, enabled by early Spanish and British explorers—but the actual story may be a bit more complex.

Also Polynesians from Easter Island have Amerindian admixture:

I am Polynesian however score some Native American. What does this mean?

Polynesians from Easter Island and natives of South America met and mingled long before Europeans voyaged the Pacific. One study by Erik Thorsby suggests Native Americans likely arrived on Easter Island shortly after Polynesians. Other scientists’ state Pacific currents and Polynesian mastery of the waves make it more likely that the Polynesians were the voyagers. They may have sailed to South America, swapped goods for sweet potatoes and other items—and returned to their island with South American women. It is possible those Polynesians on Easter Island traveled back west to trade with east Polynesian countries. As you can see there are many possibilities.

You may have had a Native American ancestor, but unless you score a good chunk of it on an autosomal test, it will be hard to confirm. The study by Thorsby stated that in the 27 living Easter Islanders who were tested, there was around 8% Native American in their genomes.

I also found modern Mayans scoring few percent of "Malayan" admixture.

The same "Malayan" admixture was present in two Botocudos (Bot15 & 17).

The Botocudo samples are not Amerindians, but fully Polynesian colonists. This is also confirmed by their Y-DNA and mtDNA.

Interesting how Kennewick man was thought to have clear European skull features yet mainstream papers that came out said Kennewick man was a full native American to debunk that. It's just some MA-1(MA-1 also has all this stuff in K36)admixture that came in with some Amerindians across the Bering Strait, along with some Amerindians having extra Siberian(and no, Amerindians still aren't a mix of East Asians and MA-1, who isn't an outlier population, given not all Amerindians score this European).
