Genetic Detection of Immigrants

Multilocus genotypes.

Detecting immigrants from the analysis of multilocus genotypes: paper here.  An old paper; of course, methodology has gone past this since; nevertheless, it deserves to be noted, for the idea that looking at multilocus genotypes allows for distinguishing genetic types even when “bean bag genetics” differentiation is low.  The basic premise; emphasis added:

Immigration is an important force shaping the social structure, evolution, and genetics of populations. A statistical method is presented that uses multilocus genotypes to identify individuals who are immigrants, or have recent immigrant ancestry. The method is appropriate for use with allozymes, microsatellites, or restriction fragment length polymorphisms (RFLPs) and assumes linkage equilibrium among loci. Potential applications include studies of dispersal among natural populations of animals and plants, human evolutionary studies, and typing zoo animals of unknown origin (for use in captive breeding programs). The method is illustrated by analyzing RFLP genotypes in samples of humans from Australian, Japanese, New Guinean, and Senegalese populations. The test has power to detect immigrant ancestors, for these data, up to two generations in the past even though the overall differentiation of allele frequencies among populations is low.

Classical theory in population genetics has focused on the long term effects of immigration on allele frequency distributions in semi-isolated populations, concentrating on the stationary distribution resulting from a balance between forces of immigration, genetic drift, and mutation (1–4). Less theory exists addressing the effect of recent immigration among populations with low levels of genetic differentiation. A theory describing the effects of immigration on the genetic composition of individuals in populations that are not at genetic equilibrium is needed to interpret much of the data being generated using current genetic techniques.

In this paper we consider the multilocus genotypes that result when individuals are immigrants, or have recent immigrant ancestry. We propose a test that allows recent immigrants to be identified on the basis of their multilocus genotypes; the test has considerable power for detecting immigrant individuals even when the overall level of genetic differentiation among populations is low. Molecular genetic techniques that allow multilocus genotypes to be described from single individuals are relatively new, and much of the information contained in these types of data is not fully exploited by estimators of long term gene flow that are currently available (5–7). We provide an example of an application of the method to restriction fragment length polymorphism (RFLP) genotypes from human populations; the method may also be applied to analyze multilocus allozyme and microsatellite data.

Also:

 At least three potentially misleading results may arise when applying the method considered here. First, the failure to reject the hypothesis that an individual was an immigrant, or descended from immigrants, may simply reflect the fact that the appropriate populations for comparison were not included in the analysis. Second, an individual might incorrectly appear to have originated in a particular population other than the one from which it was sampled. This might be due to similarities in allele frequencies, due to long-term gene flow, between that population and a third population from which the individual actually originated, but which was not included in the sample of populations. Third, the fact that many pairwise comparisons between populations are performed for each of a large number of individuals means that some individuals will appear to be immigrants purely by chance.

See this as well.  And also this.

In the late 1990s and early 2000s, there was some work going on in population genetics concerning multilocus genotypes.  A lot of good could have come from that if it was continued.  By an interesting coincidence, work on this subject essentially ended around the same time Der Movement and the HBDers went online talking about, and dissecting, population genetics studies.  It could be a coincidence, but given how most population geneticists are hysterical SJWs, maybe some of them decided not to investigate areas of their field that would focus attention on the great degree of actual ethnoracial differentiation that exists when genetic structure is taken into account.

Siberian Gene Flow into Europe

Raciology alert!

Something to read, emphasis added:

Siberia and Northwestern Russia are home to over 40 culturally and linguistically diverse indigenous ethnic groups, yet genetic variation and histories of peoples from this region are largely uncharacterized. We present deep whole-genome sequencing data (∼38×) from 28 individuals belonging to 14 distinct indigenous populations from that region. We combined these data sets with additional 32 modern-day and 46 ancient human genomes to reconstruct genetic histories of several indigenous Northern Eurasian populations. We found that Siberian and East Asian populations shared 38% of their ancestry with a 45,000-yr-old Ust’-Ishim individual who was previously believed to have no modern-day descendants. Western Siberians trace 57% of their ancestry to ancient North Eurasians, represented by the 24,000-yr-old Siberian Mal’ta boy MA-1. Eastern Siberian populations formed a distinct sublineage that separated from other East Asian populations ∼10,000 yr ago. In addition, we uncovered admixtures between Siberians and Eastern European hunter-gatherers from Samara, Karelia, Hungary, and Sweden (from 8000–6600 yr ago); Yamnaya people (5300–4700 yr ago); and modern-day Northeastern Europeans. Our results provide new insights into genetic histories of Siberian and Northeastern European populations and evidence of ancient gene flow from Siberia into Europe.

Perhaps some of that leaked into the David Bromstad and Bjork family lines. Actually, Bromstad would seem to be a solid candidate to be recruited by HopeNotHate for their next Alt Right infiltration.  Infiltrate the Nutzis as well.  And if the Alt Wrong mistake him for a high-IQ Chinaman, so much the better, although I suspect the Alt Wrong and the Nutzis, with their yellow fever, would be more prone to accept Bjork as an infiltrator.


In any case, the idea of absolute racial purity takes another hit, and the unscientific “hypodescent” paradigm, as applied to Old World demographics, is again shown to be untenable, unless all of Northeastern Europe is now to be considered “Asian.”

Another 23andMe Fail

In a word: hogwash.

I’ve seen the “timeline” “data” from a number of people, and it’s all been as absurd as that (or more so).   If DNAPrint as “bad,” how is 23andMe better? In a gross sense it is, but in a net sense, compared to the “state of the art” at the time, and given what we should expect in 2017, and given Der Movement fantasies about absolute accuracy and precision, it’s not. For majority ancestry, no problem, but for fine-grained analyses – not good at all.

And when are any of these companies going to provide genetic kinship data to established ethnic and racial categories?  Of course, academic population geneticists shy away from genetic kinship data as well – after all, we can’t let the rubes know who they are most related to, can we?  I mean, they might get all, like, racist on us and all.

Genetic Continuity in the Levant

Extant Canaanites.

The Canaanites inhabited the Levant region during the Bronze Age and established a culture that became influential in the Near East and beyond. However, the Canaanites, unlike most other ancient Near Easterners of this period, left few surviving textual records and thus their origin and relationship to ancient and present-day populations remain unclear. In this study, we sequenced five whole genomes from ∼3,700-year-old individuals from the city of Sidon, a major Canaanite city-state on the Eastern Mediterranean coast. We also sequenced the genomes of 99 individuals from present-day Lebanon to catalog modern Levantine genetic diversity. We find that a Bronze Age Canaanite-related ancestry was widespread in the region, shared among urban populations inhabiting the coast (Sidon) and inland populations (Jordan) who likely lived in farming societies or were pastoral nomads. This Canaanite-related ancestry derived from mixture between local Neolithic populations and eastern migrants genetically related to Chalcolithic Iranians. We estimate, using linkage-disequilibrium decay patterns, that admixture occurred 6,600–3,550 years ago, coinciding with recorded massive population movements in Mesopotamia during the mid-Holocene. We show that present-day Lebanese derive most of their ancestry from a Canaanite-related population, which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age. In addition, we find Eurasian ancestry in the Lebanese not present in Bronze Age or earlier Levantines. We estimate that this Eurasian ancestry arrived in the Levant around 3,750–2,170 years ago during a period of successive conquests by distant populations.

So, essentially, modern-day indigenous Lebanese demonstrate highly significant – the large majority of their ancestry – genetic continuity with ancient Canaanites, with some more minor “Eurasian” admixture, tied to historical events, which mostly took place during the “ancient” Classical era.

Likely, most indigenous peoples would represent significant genetic continuity with ancient peoples that occupied the same territories, with of course some degree of subsequent admixture, some of which would be “ancient” and some “modern.”  There would be exceptions, there are always exceptions, and the degree of admixture would vary from case to case. But one suspects that continuity is greater than what Der Movement typically postulates, with its breathless accounts of retconned population changes to explain whatever ethnic fetishism is in style at any particular time. Changes in population character are more likely to be due to dysgenic degeneration of native stocks than it is wholesale population replacement, or admixture of such an extent that it is practically equivalent to population replacement. No doubt such extreme cases have occurred in human history, but those are the (relatively rare) exceptions, not the rule.

The problem of course is that today, European-derived peoples are actually faced with real population replacement, dealing with a catastrophic combination of extremely low birthrates, mass migration of far more fecund alien peoples, and treasonous native elites (coupled to clever anti-White aliens) dedicated to facilitating native race replacement.  However, one cannot always project current trends to past eras. Sometimes, perhaps. Always, no.

Of Declines and Falls

Not always an alien influx followed by racial admixture.

One of Der Movement’s favorite memes is the idea that national decline and the fall of civilizations always have an external racial basis – i.e., the decline and fall occurs as a result of some sort of alien influx followed by “racial admixture.”

A look at history provides many counter-examples.  Consider the Italian Renaissance, centered on North-Central Italy, particularly Tuscany-Florence. The great intellectual ferment there changes the world and then essentially vanished, all without the influx/admixture model being relevant.  What happened to the great Italian artists like Michelangelo and the all-around figures like Alberti and da Vinci?  Where are the great German composers today?  After Nietzsche and Heidegger, what happened to German philosophy?  What happened to French culture and French martial glory? Where’s the English Dickens and Shakespeare today?  Isn’t it true that the Third World influx into Great Britain occurred after, not before, they lost their empire?  Spain lost their empire, but that empire was formed after they had thrown off centuries of Arabic rule; it wasn’t that the “Arab influx” was responsible for Spain’s fall.  Does anyone really believe Portugal lost their empire because of “an influx of Negro blood?”  Was it really possible for a small nation like Portugal could maintain their lead in exploration and colonization after larger European nations got involved?  Did “racial admixture” lose the Netherlands most of their overseas possessions?  Did the transformation of Scandinavians from Vikings to SJW social democrats involve “racial admixture” or did the alien invasion of that part of Europe occur after the behavioral and cultural changes?

In these cases, to the extent the problem was biological, it was internal – dysgenics including the counter-selective effects of war, Frost’s genetic pacification, and the breeding of the unfit and the botched – as well as cultural/historical (Spengler?).  In many cases, alien influx and admixture, when it has occurred, was the consequence, not the cause, of decline. One can speculate that the Ancient World was similar.  In some cases of course, admixture may have caused decline (Ancient Egypt?  The Middle East?) but that’s as much the exception as it is the rule.

But Der Movement can’t get is head around such ideas, just as their heavy breathing about Paleolithic/Neolithic differences in Europe typically doesn’t understand that such differences were in place long before the beginnings of the Ancient World’s Classical Civilizations.

I would invoke “cognitive dissonance” here, but that implies some sort of cognitive process to begin with.


A note:


It’s a bit humorous that the same Alt Right that has disdain for S. Italians also has an obsessive man-crush on Julius Evola who is described thus:

Giulio Cesare Andrea Evola was born in Rome to a minor aristocratic family of Sicilian origins.


Again, I could say “cognitive dissonance” but that implies some degree of cognitive function, and I’m not sure how much of that Der Movement actually has.

More Amren Lies on Lynn’s Pseudoscientific Fraud

Amren is an embarrassment.

In the last edition, the Balkan countries were shown to have lower IQs than Western Europe. Lynn argues that they are clines, reflecting genetic admixture with peoples from the Near East, where the IQs are in the range of approximately 90 (Turkey), 87 (Lebanon) and 83 (Syria) and hence the peoples of the southern Balkans are a mixed race cline of European and Near-Eastern populations with IQs intermediate between the two peoples.


Absolute retardation. Note the word “hence.” Essentially, the senile fool is saying that admixture exists because his “estimated” IQ scores are in between the populations – as if (falsified) IQ score differences prove (or determine?) a “racial cline.” There is absolutely no evidence for any such cline, assuming that Lynn is not so absolutely stupid to confuse Neolithic farmer ancestry with modern Near Eastern ancestry – particularly stupid since varying degrees of Neolithic ancestry is found throughout Europe. Thus, the groups that Lynn calls “European” have the same ancestry (to a lesser degree) as the others. Even if all of this is true, one thing does not necessarily cause another. Even IF the IQ scores were intermediate between two populations does not mean that the population with those scores are genetically/racially intermediate between the other two populations.

Likewise, in the last edition, Lynn noted that Portugal’s IQ was significantly lower than other Western European countries, something he put down to Early Modern African slaves, an issue which was not a factor in Spain, for example.

So, the retard is arguing that the admixture exists in Portugal, but not at all in Spain? What about the “North African” admixture (which carries some sub-Saharan genes)? Lynn is a pathetic joke.

In this edition, it is shown that the IQ in the far south of Western Europe is, in general, significantly below 100.

That is not true.

In Sicily and in the South of mainland Italy it is 90, and in southern Spain it is 95.5.

That’s from Lynn’s “estimates.” However, as discussed previously at this blog, there is ZERO real evidence for these IQ scores based on actual IQ data. ZERO. There are data that the IQs throughout Italy are similar, and there is also data that IQs in the south may be higher.

Lynn argues that the populations here are a European-North African cline, so the IQ is intermediate between Europe and North Africa.


What an idiot. North African input here is maybe, at most, at the level of ~ 5% at most, which is not, as Lynn implies, some sort of half-way intermediate admixed cline. That low level of admixture is not reasonably plausible as a possible source of depressing IQ to the absurdly low levels that Lynn “estimates.” In reality, the Mediterranean Sea has been an effective genetic barrier. Those Southern European populations are NOT “racial clines.” They are European populations with low levels of “exotic admixture” at levels comparable to admixture (of varying types/origins) found in different parts of Europe.

He quotes many expert sources–often verbatim and at length–to back up these interpretations and also substantiates his interpretation with gene frequency data.

Expert sources? The sources linked in his published papers were laughable and his interpretations of population genetics were comical, cherry picked nonsense. Again: there is ZERO evidence that actual IQ in Southern Europe is as low as Lynn asserts, and there is ZERO evidence that these populations are some sort of heavily admixed “racial cline.” Admixture exists throughout Europe at low levels; but of course, an Asiaphile like Lynn would consider East Asian admixture is a positive thin (boosting IQ, I suppose). The autosomal data linked in this post do not support the implication of a heavily admixed “cline” radically different from other parts of Italy or Spain. The differences are relatively minor and consistent with the “genes mirror geography” gradual clines found tthroughout Europe as a whole. Does this image suggest any sort of radical “racial cline” within Italy (North-Central-South)?


That Amren is still pushing Lynnian crap (while they still kowtow to Jews) tells you all you need to know about the destructive stupidity, mendacity, and cowardice of the conservative-HBD faction of Der Movement. Pushing outright LIES and pseudoscientific distortions – a complete embarrassment. Interesting how Jews have to be treated with “kid gloves” for political expediency, but White gentile ethnics can be lied about with impunity. The truth about Jews must be covered up, while fantastic inventions about dagoes must be promoted. I can’t seem to remember that Jefferson quote suggesting we need to lie to protect non-European peoples, yet promote falsehoods about Europeans.


Even AFTER Lynn has been refuted on these issues, Amren still promotes these lies. Amren seems emotionally beholden toward lying to their readers. Amren is pitiful – part of the problem, not the solution. 

Dienekes on U6

An Eurasian origin?


Ordinarily, I have zero interest in mitochondrial and NRY DNA studies, but there is an underlying issue here that is relevant to the important autosomal DNA – some of what has been considered “admixture” may not be, it may be due to a misunderstanding of haplotype/haplogroup origins or, for autosomal DNA, a lack of proper parental populations (or a lack of application of statistical significance).  Or, a failure to go back far enough.  That may or not be the case here, but in population genetics, as in science as a whole, there is never a “final answer” – new data should can always alter beliefs/hypotheses.

In any case, the “racial purity” meme is less relevant to EGI than is genetic kinship, an all-encompassing concept that takes into account all sources of genetic divergence (including real admixture), to establish the genetic benefits and costs of different biopolitical scenarios.
