    Could this be our first Iron Age Greek sample?
    In PCA (Fig. 1C-D), most of the individuals from Emp˙ries form two clusters: one (which we call Emp˙ries1) plotting close to the Iron Age Iberia cluster that includes samples from the nearby site of Ullastret and the other(which we call Emp˙ries2) plotting close to Bronze Age samples from the eastern Mediterranean such as the Mycenaean samples from Greece
    Using this setup, all the 1-way models failed(P-value<3.69E-14)except for the Mycenaeans(P-value==8.81E-01), indicating that Empuries2and the Mycenaean samples form a clade with respect to the rest of the groups in the populations set to the limits of our resolution.This result is perhaps not surprising given that the available Mycenaean samples from southern Greece lived only ~700 years before the founding of Emp˙ries by Greeks from Phocaea ~575 BCE, according to historical sources.

    * BAL001 and BAL005 are the same individual. It appears as BAL051 along the manuscript

    I1 in BAL051 (Azilian) is kind of interesting. R1b in Cardial (probably V88) is to be expected as was probably lurking in the Adriatic area.

    Some interesting and enlightening quotes.

    Middle Ages

    " Unlike in Central or Northern Europe, where Steppe ancestry likely marked the introduction of Indo-European languages (12), our results indicate that, in Iberia, increases in Steppe ancestry were not always accompanied by switches to Indo-European languages. North African ancestry, probably related to the well-known mobility patterns during the Roman Empire(22) or to the earlier Phoenician-Punic presence (23); the latter is also supported by the observation of the Phoenician-associated Ychromosome J2 (24). Gene flow from North Africa continued into the Muslim period, as is clear from Muslim burials with elevated NorthAfrican and sub-Saharan African ancestry (Fig.2D, fig. S4, and table S22) and from uniparentalmarkers typical of North Africa not presentamong pre-Islamic individuals (Fig. 2D andfig. S11). Present-day populations from southern Iberia harbor less North African ancestry(25) than the ancient Muslim burials, plausibly reflecting expulsion of Moriscos (former Muslims converted to Christianity) and repopulation from the north, as supported by historical sources and genetic analysis of present-daygroups (25)."
    The Reconquistada is real?

    YDNA remplacement in the Bronze Age.
    The earliest evidence is in 14 individuals dated to~2500–2000 BCE who coexisted with local people without Steppe ancestry (Fig. 2B ). These groups lived in close proximity and admixed to form the Bronze Age population after 2000 BCE with~40% ancestry from incoming groups (Fig. 2Band fig. S6). Y-chromosome turnover was evenmore pronounced (Fig. 2B ), as the lineages common in Copper Age Iberia (I2, G2, and H) were almost completely replaced by one lineage, R1bM269. These patterns point to a higher contribution of incoming males than females, alsosupported by a lower proportion of nonlocal ancestry on the X-chromosome (table S14 and fig.S7).

    This can go one of two ways. Either the lingusitics didn't shift in Iberia from the Neo/CA when the genome was replaced by 40%, or someone would need to prove that Iberian related languages were spoken deep within Germany around 2500 BC, and was brought by the ~90% (my guess) or so male replacement.

    Or by the Iron Age IE people with steppe dna had married into non-IE cultures that managed to hang onto their non-IE languages. That sort of thing isn't unheard of. Lots of IE-speaking people were absorbed by the Turks, for example.
