According to mainstream scientists. Not even these people (who have lived isolated and inbred for 60,000 years) are "pure". No one is pure. Race isn't allowed to exist. Ever. People's ancestry doesn't cluster "discretely enough" by their standards and never will.

You have nothing to back that number up.
Even today they probably aren't completely isolated. Andamanese groups historically traded with them and that may never have stopped. It's just modern civilizations that they reject any contact with due to some colonial shenanigans that happened in the 1880's.

They share a lot of cultural customs with the Jarawa and Onga so gene flow may still be ongoing, albeit among protected tribes.

Could be both survival and stopping foreign invaders they hunt.

>>16968818
The 1880s reference is to Portman's expeditions. He took several Sentinelese by force for "study" in Port Blair, several died quickly, the others were returned with gifts. The rejection of contact is usually dated to that. Whether trade with Jarawa continued after that point is genuinely not well documented, the isolation of the island makes it hard to say.

Oh look at that, at 2D map of DNA. Blessed math, the genetic code isnt millions of bases anymore, two numbers suffice

According to your plot these are the most quintessentially European people in existence, with almost no trace of african or asiatic admixture.

Good to know

Adding onto this, they did make contact with modern civilization in the 1800s and many of them died from diseases.
>>
>>16968915
Yes, tell me again how you represent millions of digits with 2 digits. Im sure it has nothing to do with the visualization limits of a 2D computer screen.

>>16968788
There's something honestly very funny about grouping together Europeans as "people who are least like Mbuti pygmies or Han Chinese"

We should collect a population of the most pygmy pygmies and the most chinese chinese and breed a population of anti-Europeans

Do you usually contradict your own opinions like this or do you just hope whoever sees it is too dumb to know what they’re looking at?
>>
>>16968787
>only 60,000 years
They almost certainly have some Neanderthal in them just like every other south Asian group
>>
>>16969789
The almost arbitrary three-way split in the middle of the west eurasian cluster is really something. A saner person might have circled the whole thing as "Caucasians" and labeled each lobe perhaps, but the editor was psychologically unable to resist drawing an imaginary line of separation between "europeans" and "arabs" or "turks"

That's not really true. There's a big censorship problem when it comes to science (https://boards.4chan.org/sci/thread/16964352#p16966091).

Also, "the expert consensus" doesn't really disagree with common sense too much (https://archive.fo/TDZem).

Here's an article that explains the existence of race: https://archive.fo/ch1Y9

Very specific african tribes can be highly genetically similar to Europeans but jews will extrapolate this to mean that race is meaningless and everything is part of one large continuum. Thoughts?

PCA isnt a representation of the data. Its a shadow of it. A projection. I know what it is, it is not a representation of the data. The data cant be graphically represented as it has millions of dimensions, and a computer screen only has 2.
You want to reduce it to two dimensions only because its what you can see (3 dimensions with a fancy holographic display or a 3D render).
This is like trying to represent a person by its shadow over a telephone pole.
>>
>>16969651
>>16969759
I seriously wonder if a Pygmy mating with a non-African has ever happened before ever
>>
>>16984431
Each dimension explains less variance. You can graphically represent 3 dimensions using PCA, but there really isn't much of a difference going from 2 to 3 dimensions, anyway.
>>
>>16984434
there are tonnes of negritos with black skin and curly hair in south east asia, in the phillippines too, the oldest ethnicities there, i think this is why the asians there look different from those in east asia
>>
>>16984437
2 or 3 dimensions are irrelevant when the source data has millions of dimensions. This is why i made an analogy of a shadow on a telephone pole. You may guess a person's height from it. Almost all information is lost just because you want to have an easy 2D display (or inconvenient but doable 3D render)

>>16968787
99.9% of DNA is identical across all humans. Race is a social construct.
>>
>>16984891
True, same as how colors are a social construct
>>
>>16984434
I recall some white guy marrying one and integrating into their tribe. Not sure if he had any kids though...
>>
>>16984891
>99.9% of DNA is identical across all humans.
Craig venter (the guy who you're implicitly citing) did a re-analysis, retracted the 99.9% claim, and stated that any two random humans will be 99.5% the same on average.

It's worth noting that on this same scale (SNPs), humans are 99% the same as chimpanzees and about 98.7% the same as gorillas.

>>
>>16984551
You aren't going to get more overlap by adding in extra dimensions for groups to differ. You see a ton of overlap with 1 dimension, almost none with 2, and even less with 3.
>>
>>16985218
>two random humans will be 99.5% the same on average
It's not useful for this data to be polluted by the similarity of humans within the same population, the similarity of humans at opposite ends of the variation is more relevant
>>
>>16985812
You would also need to exclude people with extreme personal mutations, like an extra chromosome
>>
>>16984437
>there really isn't much of a difference going from 2 to 3 dimensions, anyway.
that depends on your data and loadings, anon.
>>
>>16985218
this is irrelevant, on average, humans are 99.9% similar, that you ignored this shows you don't know statistics
>>
>>16986216

There's no denying at this point that the eugenicists were right.

Still unaddressed I see. Predictable.

>>16986273
I don't see the label "European" anywhere in that plot. Are you sure you're not having another episode of ashkenazi schizophrenia?
>>
>>16986275
The big red square in the top right is labelled “Europeans”

Ok. Looks like I was being even more retarded than you.

Why don't they have a society and built their own small businesses if Whitey didn't come to oppress them? Lol.
