Epigravettian migrations 3,000 years before Villabruna

epigravettian-magdalenian-tagliente

Open access Early Alpine human occupation backdates westward human migration in Late Glacial Europe, by Bortolini et al. bioRxiv (2020).

Interesting excerpts (emphasis mine):

To understand the full extent of the role played by demic processes in this key transition in Late Glacial Europe we focused on the left hemimandible of an individual found at Riparo Tagliente (Tagliente2) associated with Late Epigravettian evidence. During the LGM and the Late Glacial, the Adriatic Sea basin played a critical role in shaping the economy and mobility of Epigravettian groups. Geomorphological and sedimentological processes linked to the extension of Alpine glaciers and

Villabruna cluster in Late Epigravettian Sicily supports South Italian corridor for R1b-V88

epipalaeolithic-whg-expansion

New preprint Late Upper Palaeolithic hunter-gatherers in the Central Mediterranean: new archaeological and genetic data from the Late Epigravettian burial Oriente C (Favignana, Sicily), by Catalano et al. bioRxiv (2019).

Interesting excerpts (emphasis mine):

Grotta d’Oriente is a small coastal cave located on the island of Favignana, the largest (~20 km2) of a group of small islands forming the Egadi Archipelago, ~5 km from the NW coast of Sicily.

The Oriente C funeral pit opens in the lower portion of layer 7, specifically sublayer 7D. Two radiocarbon dates on charcoal from the sublayers 7D (12149±65 uncal. BP) and 7E,

“Steppe ancestry” step by step: Khvalynsk, Sredni Stog, Repin, Yamna, Corded Ware

dzudzuana_pca-large

Wang et al. (2018) is obviously a game changer in many aspects. I have already written about the upcoming Yamna Hungary samples, about the new Steppe_Eneolithic and Caucasus Eneolithic keystones, and about the upcoming Greece Neolithic samples with steppe ancestry.

An interesting aspect of the paper, hidden among so many relevant details, is a clearer picture of how the so-called Yamnaya or steppe ancestry evolved from Samara hunter-gatherers to Yamna nomadic pastoralists, and how this ancestry appeared among Proto-Corded Ware populations.

Dzudzuana, Sidelkino, and the Caucasus contribution to the Pontic-Caspian steppe

hunter-gatherer-pottery

It has been known for a long time that the Caucasus must have hosted many (at least partially) isolated populations, probably helped by geographical boundaries, setting it apart from open Eurasian areas.

David Reich writes in his book the following about India:

The genetic data told a clear story. Around a third of Indian groups experienced population bottlenecks as strong or stronger than the ones that occurred among Finns or Ashkenazi Jews. We later confirmed this finding in an even larger dataset that we collected working with Thangaraj: genetic data from more than 250 jati groups spread throughout India (…)

Palaeolithic Caucasus samples reveal the most important component of West Eurasians

dzudzuana-ancestry-europe

Preprint Paleolithic DNA from the Caucasus reveals core of West Eurasian ancestry, by Lazaridis et al. bioRxiv (2018).

Interesting excerpts:

We analyzed teeth from two individuals 63 recovered from Dzudzuana Cave, Southern Caucasus, from an archaeological layer previously dated to ~27-24kya (…). Both individuals had mitochondrial DNA sequences (U6 and N) that are consistent with deriving from lineages that are rare in the Caucasus or Europe today. The two individuals were genetically similar to each other, consistent with belonging to the same population and we thus analyze them jointly.

(…) our results prove that the European affinity of

Earliest modern humans outside Africa and ancient genomic history

palaeolithic

Interesting new paper at Science, The earliest modern humans outside Africa, by Hershkovitz et al., Science (2018) Vol. 359, Issue 6374, pp. 456-459

Introduction:

Recent paleoanthropological studies have suggested that modern humans migrated from Africa as early as the beginning of the Late Pleistocene, 120,000 years ago. Hershkovitz et al. now suggest that early modern humans were already present outside of Africa more than 55,000 years earlier (see the Perspective by Stringer and Galway-Witham). During excavations of sediments at Mount Carmel, Israel, they found a fossil of a mouth part, a left hemimaxilla, with almost complete dentition.

The sediments
