    Genomic signals of migration and continuity in Britain before the Anglo-Saxons

    ^^ More about 3DRIF-26 (the "Roman skeleton [...] of exogenous origin"), from the study:

    One York Roman 3DRIF-26 gives a clear Middle Eastern signal, with closest neighbours of Palestinian, Jordanian and Syrian origin. This dichotomy is also apparent in maximum likelihood estimation of individual ancestries using NGSadmix (Fig. 1b). In this, when a model of three ancestral populations is imposed across the entire sample, this analysis highlights three major geographical foci: Europe; North Africa; and West Asia/Middle East. The European ancestral component predominates in the majority of ancient samples (which show similar profiles to modern northwestern Europeans), whereas 3DRIF-26 again shows a majority West Asian/Middle Eastern component. Isotopic analyses of the skeletons support this genetic differentiation of 3DRIF-26 from the remainder of the individuals sampled. Strontium isotope ratios (87Sr/86Sr) vary mainly according to geological substrate, while oxygen isotope values (q18O), which track locally available drinking water, reflect climatic and geographic variables such as temperature, rainfall levels or distance from the coast22. When we compared these ratios in our seven samples with other British Romans, 3DRIF-26 showed both an unusually low 87Sr/86Sr ratio and an extreme q18Op value (Supplementary Fig. 2).

    [...]

    Interestingly, the top-ranked modern sample for IBS for each of these ancient British samples was one of the formerly Celtic language-speaking regions of the British Isles, with the single exception of 3DRIF-26, which showed highest IBS with samples from Saudi Arabia. We gauged the sensitivity of this approach by checking whether individual modern samples were assignable to their region of origin. When tested, local individuals were assigned with high frequency (0.97) to the British Isles and also most often to their correct country. The method showed lower sensitivity for Middle Eastern genotypes, with primary assignment to that region in only 39% of instances (Supplementary Fig. 15). Nevertheless, outside assignments tended to be to Cypriot, Sardinian and Druze, never to Northern Europe. In contrast, specificity of a Middle Eastern assignment was high—only three individuals, from Iran, Tunisia and Morocco, were incorrectly assigned to that region. Thus, assignment of 3DRIF-26 to the Middle East region seems secure, but resolution to an individual population may not be possible. Specificity in assignment to the British Isles was lower, with about half of assignments (0.53) derived from elsewhere, most often from neighbouring populations such as France (0.28) and Norway (0.15). Small sample sizes (B10 per population) render individual scores only weakly informative but, when we compared the six Roman burials after excluding the outlying 3DRIF-26, their rank orders across the geographical sample were highly correlated (Spearman rank correlation coefficients (r ¼ 0.982; Po0.01; Supplementary Note 2, Supplementary Figs 12–14 and Supplementary Tables 11 and 12).

    [...]

    Five samples returned imputed lactase persistence genotypes: two Roman burials and the Iron-Age individual were likely to have been lactase persistent, while two Romans, 6DRIF-22 and the suspected migrant 3DRIF-26 were homozygous for the ancestral non-persistence variant.

    [...]

    Combined genomic and isotopic evidence support the inference that the origins and childhood of individual 3DRIF-26 lay far outside Britain. His modern genomic affinities clearly lie with the Middle East. Isotopically, the most plausible suggestion is an arid environment on igneous or limestone geology, which is consistent with the same regions (Supplementary Fig. 2 and Supplementary Note 2). Hence, although this individual is indistinguishable from the other inhumations in terms of burial practice and osteology, the analyses show that, even in its northernmost provincial capital, the profoundly cosmopolitan nature of the Roman Empire suggested by documentary and epigraphic sources continued to hold sway.


    Here's the PCA plot (Fig.1):



    3DRIF-26 carried Y-DNA haplogroup J2 and mtDNA haplogroup H5, more resolution on these markers could enable us to make educated regarding his place of origin.

    Genomic signals of migration and continuity in Britain before the Anglo-Saxons

    This is a thread for the new Martiniano et al. paper.

    The purported migrations that have formed the peoples of Britain have been the focus of generations of scholarly controversy. However, this has not benefited from direct analyses of ancient genomes. Here we report nine ancient genomes (~1 ×) of individuals from northern Britain: seven from a Roman era York cemetery, bookended by earlier Iron-Age and later Anglo-Saxon burials. Six of the Roman genomes show affinity with modern British Celtic populations, particularly Welsh, but significantly diverge from populations from Yorkshire and other eastern English samples. They also show similarity with the earlier Iron-Age genome, suggesting population continuity, but differ from the later Anglo-Saxon genome. This pattern concords with profound impact of migrations in the Anglo-Saxon period. Strikingly, one Roman skeleton shows a clear signal of exogenous origin, with affinities pointing towards the Middle East, confirming the cosmopolitan character of the Empire, even at its northernmost fringes.
    These results, probably to no one's surprise, don't exactly support the old idea of Iron Age Celts being "Mediterranean" but they sure look Welsh and Irish. Further, it appears one can be similar to Anglo-Saxons without being close to Celts but not vice versa.



    IBS-similarity scores. 3DRIF-26 has J2-L228 and indeed looks autosomally Near Eastern, all other DRIF are R1b. Anglo-Saxon is I1-S107.

    Interesting that, of the R1b Roman males, two were R1b-U106, one was R1b-U152, and one was R1b-DF63 (downstream of L21).

    I have not had time to read the paper in detail, but apparently they were all either gladiators or possibly Roman military men.

    I glanced through it kind of fast, but were all of them decapitated? Is that right?

    The paper says that the bodies fit the profile of gladiators buried in a different cemetery or they could have been Roman soldiers..either way, it states they were of British origin.

    3DRIF-26 clusters with Levant(Palestine, Jordan) on PCA and in ADMIXTRUE scores most similar to to Levant(Palestine, Jordan). He was definitely from Levant, because it was apart of the Roman empire. He can be used to test how much of a genetic affect the expansion of Islam had on the Levant. He also is a good proxy for the non-European ancestors of European-Jews.

    3DRIF-16 and 3DRIF-3 were R1b-U106 (they're both listed as R1b-M405/S21 in the study), I find that rather interesting, it would seem not all U106 arrived in the Isles with the Anglo-Saxons, this marker's sheer diversity in Britain already suggested that IMO.
    6DRIF-22 was R1b-U152 (listed as S28), here's what we can read in the sup data:

    "In R1b* derived European Y-*chromosomes, L52 lineages are present in more than 90% of Europeans, and are characterized by a frequency gradient towards the West of Europe. There is a resemblance between R1b-*M269 and L52, except that the latter is seen at much lower frequencies in the East of Europe. This trend is also observed at the level of the British Isles, where L52 reaches its highest frequencies in Wales, Ireland and Scotland. All Roman York samples were assigned to L52/L11, either by direct observation of the derived alleles, or by belonging to sub*lineages that imply membership to this branch. Deeper phylogenetic resolution was achieved for some of the samples: 3DRIF*16 and 6DRIF*3 are derived for S21/M405, which can be detected in ~60% of M269+ Y*chromosomes in Central Europe, 6DRIF*21 belongs to DF63, a sub*lineage of S145/L21, more commonly found in the British Isles, in particular Ireland and Wales, and 6DRIF*22 was identified as belonging to haplogroup S28, present in modern* day Switzerland, Italy and France, but also reaches over 15% in certain English and German regions. Sample 3DRIF*26 is clearly an exception, both in terms of autosomal variation as in the Y-*chromosome lineage it presents (J2), common in the Middle East, Caucasus, Balkans and Italy and attributed to neolithic demic migrations or to seafaring Phoenicians. The Anglo-*Saxon sample (NO3423) was assigned to I1 lineage, characterized by higher frequencies Nordic countries and in a british context it is more common in East/Central England with a decrease in frequency towards the West and this distribution has been interpreted as Anglo-*Saxon mass migrations into Britain."

    Well, they were Romano-Brits at least, grown locally. Interesting collection of y haplogroups. Thus far, that's the earliest U106, U152 and DF63 in Britain.

    Here we are, finally autosomal aDNA from the ancient Middle East (through Britain ) that looks modern. 2000 years old isn't very ancient indeed but it predates the islamic period that supposedly completely changed the face of the region.


    In the supplements, 3DRIF-26 clusters with Syrians in terms of African ancestry but not in the Middle East + North Africa PCA where he's closest to UAE. I must say I don't like the PCA because it's - as always - hijacked by Mozabites and Bedouins but it's pretty clear this individual is a bit different from modern non-bedouins Levantines.

    From the supplementary materials:

    Sr*isotope and concentration and oxygen isotope data for 3DRIF*26 is inconsistent with Europe and
    consistent with origins on basalt or limestone terrains in a hot, dry region of northern Africa or the
    Levant.
    Dietary (C and N) isotope data are consistent with this and suggest a childhood in an area where
    aridity had a significant effect on δ
    15N values but were C4*plants or marine resources made no significant
    contribution to the protein intake. Origins for all other individuals in Britain cannot be ruled out but have
    potentially important implications for the definition of the British isotope range.
    This Y-DNA J2 man was genetically MENA and the isotope data point to that as well.
