Was the four race theory actually correct?

Notice how the Mediterranean people are closer to africa. North Africans and southern europeans are part african, at least that is what I believe.

Knowledge of human origins, migrations, and expansions is greatly enhanced by the availability of large datasets of genetic information from different populations and by the development of bioinformatic tools used to analyze the data. We present Ancestry Mapper, which we believe improves on existing methods, for the assignment of genetic ancestry to an individual and to study the relationships between local and global populations. The principle function of the method, named Ancestry Mapper, is to give each individual analyzed a genetic identifier, made up of just 51 genetic coordinates, that corresponds to its relationship to the HGDP reference population. As a consequence, the Ancestry Mapper Id (AMid) has intrinsic biological meaning and provides a tool to measure similarity between world populations. We applied Ancestry Mapper to a dataset comprised of the HGDP and HapMap data. The results show distinctions at the continental level, while simultaneously giving details at the population level. We clustered AMids of HGDP/HapMap and observe a recapitulation of human migrations: for a small number of clusters, individuals are grouped according to continental origins; for a larger number of clusters, regional and population distinctions are evident. Calculating distances between AMids allows us to infer ancestry. The number of coordinates is expandable, increasing the power of Ancestry Mapper. An R package called Ancestry Mapper is available to apply this method to any high density genomic data set.

excuse my ignorance, but what is "four race theory"?

 

[The Real]

No.

 

[Brown_Pride]

interesting....
sorta makes sense though. People in america are one group
People in europe are another
people in africa are another
and people in east asia are another

There's a lot of bleed over in terms of asia and east asia.

I'm not sure this shows us anything outside of migration propensity...which isn't really saying much about "race". The fact that there are 4 data groups is just coincidence. Especially considering they've group Scandinavians with Arabs.

the four race theory is a classification of humans based on average skull measurements

the negroid: africans and some populations in south east asia.
the Mongoloid: east asia, south east asia, and the american natives
The caucasoid: arabians, south asians, europeans and west asians .
The australoid: australia, melanesia, and papua new guinea
