    Genetic Origins of Minoans and Mycenaeans

    YEAH! Finally.

    See: Lazaridis et al

    "The origins of the Bronze Age Minoan and Mycenaean cultures have puzzled archaeologists for more than a century. We have assembled genome-wide data from 19 ancient individuals, including Minoans from Crete, Mycenaeans from mainland Greece, and their eastern neighbours from southwestern Anatolia. Here we show that Minoans and Mycenaeans were genetically similar, having at least three-quarters of their ancestry from the first Neolithic farmers of western Anatolia and the Aegean1, 2, and most of the remainder from ancient populations related to those of the Caucasus3 and Iran4, 5. However, the Mycenaeans differed from Minoans in deriving additional ancestry from an ultimate source related to the hunter–gatherers of eastern Europe and Siberia6, 7, 8, introduced via a proximal source related to the inhabitants of either the Eurasian steppe1, 6, 9 or Armenia4, 9. Modern Greeks resemble the Mycenaeans, but with some additional dilution of the Early Neolithic ancestry. Our results support the idea of continuity but not isolation in the history of populations of the Aegean, before and after the time of its earliest civilizations."

    The Bronze Age Anatolia individual:
    "This individual wasancestral for the major subclade3 P58 (J1a2b; previously designated3 J1e) and could thus bedesignated as J1a(xJ1a2b)."

    "I0070 (Minoan from Lasithi)This individual was derived for mutation M319:15467785T->A (J2a1d) as well as upstream mutationsL26:22942897T->C (J2a1) and M410:2751678A->G, L212:22711465T->C (J2a). He was not foundto be ancestral for any downstream mutations and could be designated as J2a1d. Haplogroup M319was found4 at a frequency of 8.8% in one sample set of 193 present-day Cretans (95% confidenceinterval from the binomial distribution 5.2-13.7%) and 5.4% in another set5 of 168 Cretans (95% C.I.:2.5-10%), but no examples were found in a combined sample set of 171 Greeks from three locationsnear early Neolithic settlements in mainland Greece (95% C.I: 0-2.1%). A re-analysis4 of large set of523 present-day Anatolian males6 revealed only 2 examples of M319 in this population (95% C.I.: 0-1.4%). Thus, it appears plausible that this represents a Y-chromosome lineage that existed in MinoanCrete but was at a lower (or absent) frequency in neighboring mainland Greece and Anatolia and itsoccurrence in present-day Cretans represents continuity with those of the Bronze Age."

    "I0073 (Minoan from Lasithi)This individual was derived for mutation L26:22942897T->C (J2a1) as well as upstream mutationsM410, L559, L152 (J2a). He was ancestral for several downstream haplogroups: M322:15469740C->A (J2a1a), L560:21899860C->T (J2a1b1a), M166:21764694C->T (J2a1b2), M68:21878700A->G(J2a1c), M339:2881367T->G (J2a1e), L24:14286528G->A (J2a1h), L88.2:17595842T->C andL198:17595861A->C (J2a1i). He could thus be designated as J2a1(xJ2a1a, J2a1b1a, J2a1b2, J2a1c,J2a1e, J2a1h, J2a1i)."

    "I9130 (Minoan from Moni Odigitria)This individual was derived for mutations CTS946:7100848A->G (G2a2b2a) and upstream mutationsF3088:20813445G->A and M3397:21605685G->C (G2a). He was ancestral for downstreammutations CTS4803:15833180G->A (G2a2b2a1b1a2a) and Z3423:19251438G->T (G2a2b2a1c1a).He could thus be designated as G2a2b2a(xG2a2b2a1b1a2a, G2a2b2a1c1a). G2a2 Y-chromosomeswere common in Neolithic Europe7, western Anatolia8,9, and Neolithic mainland Greece9. We havealso re-analyzed data from a recent study of central Anatolian Neolithic genomes10, determining thatthey were present there during both the Aceramic phase at Boncuklu (2 G2a2b2b samples) and later atTepecik-Çiftlik (1 G2a2a sample). Plausibly, the Minoan from Moni Odigitria who belonged to thislineage was also related to the same group of early Neolithic farmers as those from Europe, mainlandGreece, and Anatolia."

    "I9041 (Mycenaean from Galatas Apatheia in the Peloponnese)This individual was derived for mutations L26:22942897T->C and F4326:23021978A->G (J2a1) aswell as upstream mutations M410:2751678A->G, L559:21674327A->G, L152:22243566C->T,L212:22711465T->C (J2a). He was ancestral for M322:15469740C->A (J2a1a), M260:15025506G->A and M92:21904023T->C (J2a1b1), M166:21764694C->T (J2a1b2), L210:16492197A->T(J2a1b3), M68:21878700A->G (J2a1c), M339:2881367T->G (J2a1e), P81:6739856G->A (J2a1g),L207.1:6753448A->G and L24:14286528G->A (J2a1h), L88.2:17595842T->C andL198:17595861A->C (J2a1i). He could thus be designated as J2a1x(J2a1a, J2a1b1, J2a1b2, J2a1c,J2a1e, J2a1g, J2a1h, J2a1i)."

    "More sampling of ancient populations is needed to establish the presence (and frequency) ofhaplogroup J in the Aegean and neighboring regions). However, (i) the great time depth of itspresence in the Caucasus/Iran, together with (ii) its low frequency/absence in NeolithicGreece/Anatolia, and (iii) its appearance in the samples of our study, lead us to believe that it mayhave accompanied the genetic admixture (Neolithic Iran/Caucasus-hunter-gatherer related) that seemsto have affected all populations in our study (Supplementary Information, section 2). Thus, the Ychromosometurnover that occurred in central Europe during the Bronze Age7,19 may also haveoccurred in the Aegean, with a different set of incoming lineages."

    So we've been saying here for a long time. Perhaps it's time to put some of the more exotic explanations to rest.
