I may have given the impression the other day that a “race” exists if and only if it shows up as a singel color (or almost a single color) on Haak’s graph. Certainly mon-=color groups satisfy the requirements for genetic distinctiveness, but mon-chronicity is not a requirement.
Homogeneity is more important than mono-chronicity.
For starters, the number of colors in certain parts of Haak’s graph pobably hhas more to do with the number of ancient skeletons that have been analyzed htan net common ancetry–as you can see from the left side of the graph, scientists have analyzed the genomes of numerous ancient European skeletons (all of which show continuity with modern European people,) but they’ve analyzed rather few ancient sub-Saharan skeletons. This isnt’ ebcause they dislike ancient sub-Saharan skeletons or anything, but because the DNA content breaks down very quickly in the Sub-Saharan environment. Many of the groups here identified as mono-chromatic or nearly mono-chromatic may begin showing up as multi-chromatic as our powers of analysis continue to develop and we learn more about ancient human migrations.
But back to homogeneity. Let’s take a look at the Japanese. (One of the Yellow/Red groups on the right side of the graph.) The Japanese genome, like most east-Asian peoples’, composed of two distinct colors. And in this case, we even have names for these two groups, the Jomon and Yayoi people (not to be confused with the Yanomami or Yamnaya.) (Maybe we should institute a system where all cultures are given a set of coordinates based on physical location and era. EG, the Jomon would be J-35N,139E-12,000BC. Okay, maybe that’s not an improvement for ordinary conversaton, though when I’m trying to look up a group like the Evens, it would be.)
But this does not mean that the “Japanese” possess a great deal of ethnic diversity. The Japanese people are fairly homogenous–notice that the border between red and yellow is very smooth. Almost every Japanese person has the exact same % of Jomon and Yayoi ancestry as every other Japanese person.
This is because the merger of the Jomon and Yayoi cultures happened a long time ago, and the modern Japanese are descended from a single, homogenous population. The Japanese are a single people.
By contrast, take a look at the Evens, a Siberian group, (E-62°N,153°E-Today.) There is no homogeneity in the Evens’ genomes; they are a very mixed group in which different individuals have vastly different genetic heritages. The Evens may exist as a cultural, ethic, or linguistic group, but genetically they are a bunch of different things. The Turks, likewise, have a very choppy profile, though in this case the anomaly is easy to figure out: some “Turks” are Greek. The Ojibwa, Nama, and Yukagir are all jagged–these are groups with a great deal of recent mixing, in which many individuals are not closely related to other group members or share much DNA with them at all.
Zooming back out, let’s take a general look at the European cultures. From Greece through Spain, southern France through Ukraine, we see a smooth, three-color pattern. The blue is perhaps most concentrated in Lithuania, the orange in the Basque, and the teal in Greeks. There is a bit of purple in the south and red in the north east. But overall, the pattern is found, with consistency and evenness, throughout Europe, and not found outside of Europe.
Yes, the borders of Europe are fuzzy–Turkey, the Caucasus, and a variety of steppe-peoples are obviously related to some of the same guys as Europeans. But these do not show the same pattern as the Europeans, and beyond these border zones, the resemblance disappears entirely.
So, yes, we may speak of the Orange/Blue/Teal people, and call the “Whites” or “Europeans” if we so desire. They are a real genetic grouping, just like the “Japanese” and the “East Asians” and the Onge.
