Dark Age Assimilation
Yet another blow to the purists.
Is this where Saint Adolf's NRY haplotype came from?
In all cases, emphasis is added.
Abstract:
Many European towns and villages trace their origins to Early Medieval foundations. In former Roman territories, their emergence has traditionally been linked to mass migrations from outside the Roman Empire. However, recent studies have emphasised local continuity with some individual-level mobility. We generated and analysed 248 historic genomes from Late Roman (3rd and 4th century CE) and Early Medieval (5th-8th century CE) burial sites in southern Germany, comparing them to over 2,500 contemporary and Iron Age genomes in addition to 1,344 modern-day genomes from Germany, Italy and Great-Britain. Despite small inferred Early Medieval period community sizes, genetic diversity exceeded that of modern German cities. In the Altheim graveyard, established in the 5th century by a group of Northern European descent, we inferred a demographic shift in the 6th century with the integration of newcomers with ancestry typical of a nearby Roman military camp, likely as a result of the collapse of Roman state structures. We reconstructed multigenerational pedigrees and, using a novel approach to infer ancestry of unsampled relatives, inferred immediate intermarriage between incoming and local groups, with a distinct tendency for men from former Roman background marrying women of northern descent. Burial proximity correlates strongly with kinship, in some cases spanning six generations. These communities were organized around small family units, exhibited loosely patrilineal or bilateral descent patterns, practiced reproductive monogamy, and avoided close-kin marriages. Such practices reflect broader transformations in family structures that began during the Late Roman period, were transferred to small agrarian societies in the Early Medieval period, and continued to shape European societies. By the 7th century, ongoing admixture had shaped genetic diversity patterns into those resembling Central Europe today.
Main points:
In the earliest phase, individuals born before 500 CE predominantly cluster with Iron Age samples from Northern and Central Europe, consistent with descent from ancestral populations further north. However, individuals born in the 6th century CE exhibit a much broader distribution in PCA space. While some still overlap with Iron Age populations from Northern and Central Europe, others show affinities to groups from the western Mediterranean, Southeast Europe, in six cases the Steppe region, or even fall completely outside the genomic variation of western Eurasia (Fig. S6.2-S6.3).
The same type of data for Southern European territories would trigger an endless series of blog comments and social media posts about “admixed Meds, True Romance, not White, etc.” Here it will no doubt be met with absolute silence from Der Movement and Der Fetishists.
This expanded genetic range indicates a substantial influx of people with diverse ancestries. Individuals from the later phase of occupation, after 600 CE, once again cluster with Northern and Central European Iron Age genomes. However, their position in PCA space shifted slightly toward Southern Europe, suggesting a degree of genetic admixture, likely occurring in the preceding 6th century.
Thus, the new population, in part ancestors of modern populations of that region, exhibited “a degree of genetic admixture.”
We next assessed population substructure over the duration of these demographic shifts. Population substructure results in a deviation from random mating, which we quantified over time with the inbreeding coefficient (F). During the 5th century, we found low F-values, indicating little population substructure. Shortly after 500 CE, F-values peaked before gradually declining toward the 7th century (Fig. 2B, Table 1). This pattern aligns with the arrival of genetically diverse groups around 500 CE, prior to their assimilation.
Again, the same data and the same wording with respect to Southern Europe would lead to endless hysteria. Not here though. Wonder why.
We then used qpAdm to model the ancestries of Altheim individuals, using various Iron Age populations as potential sources (SI Chapter S7, External_Data_Table_2.3).
Supervised admixture. Do I like the methodology? No, not really. But goose and gander. Der Retards do not get to pick and choose when they accept the methodology and when they do not.
Consistent with the patterns identified using PCA and F-statistics, the majority of 5th-century individuals (81%) can be modeled as deriving their ancestry exclusively from Northern and Central European Iron Age populations (hereafter IA-NC).
Subsequently…
During the 6th century, 51% of genomes are still best described by 100% IA-NC ancestry…
81% to 51%.
… while the remaining individuals exhibit partial or complete ancestry from Iron Age populations of the western Mediterranean, the Balkans, or western Anatolia. Since qpAdm modeling revealed no clear genetic differentiation among Iron Age groups from the more southern sources — often identifying them interchangeably as potential sources of ancestry — we collectively refer to them as “Iron Age - Southeast” (hereafter IA-SE).
The wogs are all the same. The modeling is clearly suboptimal, but these types of studies are “grist for the mill” for Der Movement, so let us continue.
This designation is based on the observation that Altheim individuals, in PCA space, display a stronger genetic affinity to Iron Age and Late Antiquity genomes from south-eastern Europe, such as those from Argamum, than to those from Italy and the western Mediterranean, such as the Spina site (see Fig. S1.19, S1.21). Additionally, five individuals show minor genetic contributions from Steppe-related populations, and one individual (Alh_245) has approximately 75% East-Asian-like ancestry (Iron Age populations from China Xianbei; Mongolia Khentii-Xiongnu, External_Data_Table_2.4-5).
Well, gee, that last individual possibly was mistaken for an ancient David Bromstad.
By the final 7th century, 94% of the individuals can be modeled as deriving all their ancestry from IA-NC — consistent with further genetic contributions from northern populations.
Right, modeled as such, but earlier “However, their position in PCA space shifted slightly toward Southern Europe.”
So, the later population must have been “tainted,” correct? Let us consider how Der Movement looks at Ancient Roman data. They assume that the intrusive elements mongrelized the native population and that there is a direct continuity between that mongrelization and modern populations, ignoring subsequent population shifts, such as the depopulation of Rome and repopulation from more rural elements, etc. Der Movement assumes that all intrusive elements left permanent taints in the genome. Very well. The same applies here. Yes, the “further genetic contributions from northern populations" superimposed on a population that was “shifted slightly toward Southern Europe” reinforced the northern character of the population. However, if Der Retards want to push a paradigm of “absolute racial purity” and of “permanent genetic taint” then it applies here as well as elsewhere. Saint Adolf’s NRY did not pop out of nowhere, amirite?
More “taint” -
While the smaller sample sizes at other archaeological sites do not allow the same fine-grained chronological analysis as in Altheim, we do find evidence of similar processes occurring throughout the region. Individual affinities towards IA-NC-like and IA-SE-like ancestries quantified with D-statistics (Fig. S8.1, External_Data_Table_2.6), for instance, confirmed an overall influx of IA-SE-like ancestry across the region…The available genomes from Eltville, located outside the former Roman frontier but close to the large Roman settlement of Moguntiacum (today Mainz), are from the 6th century and represent the full spectrum from IA-NC to IA-SE…The studied Early Medieval settlements from the Danube-Isar area consistently exhibit the full spectrum from IA-NC to IA-SE ancestry…
Full spectrum.
Demographic shift prompted by intermarriage between newcomers and locals
So it ain’t so!
In line with the notion of a rapid assimilation of 6th-century people from a Roman background… During this Late Roman period, the region was home to both individuals from a non-Roman context displaying northern ancestry (sites Pförring and Kemathen) and a genetically diverse Roman military population (site Straubing-Azlburg). In Altheim, evidence of gene flow between these groups is apparent in 6th century marriages between newcomers from Roman settlements and established local families, marking a phase of integration.
Assimilation and integration…the usual pattern of female-driven exogamy:
The rapid absorption of newcomers with a Roman background into local families of primarily northern European descent is well illustrated by the family with predominantly IA-SE ancestry…all had wives with D-values indicative of more IA-NC-like ancestry. This is a general trend, with females in Altheim having lower D-values than males (Wilcoxon p=0.035, Fig. S13.1). This likely reflects a continuous flow of IA-NC-like females from the northern hinterland, thereby explaining the later reduction of IA-SE-like ancestry in southern Germany, particularly if the IA-SE-like ancestry entering Altheim was primarily driven by a pulse of males from the Roman centres in the Danube-Isar region.
Note this:
Nearly all Early Medieval cemetery population samples in southern Germany exhibit high diversity across all measurable indices, including π, θ, mitochondrial and Y-chromosomal haplotype diversity, and PCA (Table 1, Table S5.1, Fig. S6.2-S6.3). The average pairwise differences (π) estimated for Altheim, for instance, exceed that of the 1000 genomes present-day reference populations (Table 1). This aligns with the observation that Early Medieval individuals from Altheim (as well as Büttelborn, Mömlingen and Weilheim) are spread across a significantly larger PCA space than individuals of modern German cities…Notably, the diversity (e.g. π) observed in Altheim was consistently high in both the 5th and 6th centuries, suggesting that the incoming groups contributed additional genetic diversity to an already genetically diverse in-situ population…
So, a pattern of increased genetic diversity, followed by consolidation and later decreased genetic diversity. Sound familiar? Roman history, perhaps? The difference is that one case (Rome) is interpreted with hysteria and the other (Germany) is ignored. Yes, the scale of the intrusive elements in this German case was smaller than migration into Rome, but the principle is the same.
Either you accept “absolute purity” or you do not. Which is it? "Purity" does not come in degrees; it either exists or it does not. Indeed, using the word "absolute" along with "purity" is redundant; however, "absolute" is useful in order to stress how stupidly (and hypocritically) fanatical Der Movement is about such things.
The standards of "purity" do not shift dependent on “how close to home” the scenario is.
Strom is correct - racial purity is something that we need to strive for toward the future, not a past state of grace from which we have fallen. That the retarded "movement" fails to realize this is another black mark against it. Of course, the current state of affairs is that we are moving to even less purity, and more admixture, in the future, but that is on us, a failure of will and of competence on our part, and has nothing to do with past realities that need to be presented truthfully.
