A combination of evidence, based on genetic, fossil and archaeological findings, indicates that Homo sapiens spread out of Africa between ~70-60 thousand years ago (kya). However, it appears that once outside of Africa, human populations did not expand across all of Eurasia until ~45 kya. The geographic whereabouts of these early settlers in the timeframe between ~70-60 to 45 kya has been difficult to reconcile. Here we combine genetic evidence and palaeoecological models to infer the geographic location that acted as the Hub for our species during the early phases of colonisation of Eurasia. Leveraging on available genomic evidence we show that populations from the Persian Plateau carry an ancestry component that closely matches the population that settled the Hub outside Africa. With the paleoclimatic data available to date, we built ecological models showing that the Persian Plateau was suitable for human occupation and that it could sustain a larger population compared to other West Asian regions, strengthening this claim.

Abstract
A combination of evidence, based on genetic, fossil and archaeological findings, indicates that Homo sapiens spread out of Africa between ~70-60 thousand years ago (kya). However, it appears that once outside of Africa, human populations did not expand across all of Eurasia until ~45 kya. The geographic whereabouts of these early settlers in the timeframe between ~70-60 to 45 kya has been difficult to reconcile. Here we combine genetic evidence and palaeoecological models to infer the geographic location that acted as the Hub for our species during the early phases of colonisation of Eurasia. Leveraging on available genomic evidence we show that populations from the Persian Plateau carry an ancestry component that closely matches the population that settled the Hub outside Africa. With the paleoclimatic data available to date, we built ecological models showing that the Persian Plateau was suitable for human occupation and that it could sustain a larger population compared to other West Asian regions, strengthening this claim.

Initial Upper Paleolithic in the Zagros Mountains

Mohammad Javad Shoaee1* Hamed Vahdati Nasab2, 3 Michael Strozum1 Peter Frenzel4 Mohammad Akhavan Kharazian5 Ricardo Fernandes1, 6, 7, 8 Seyed Milad Hashemi2, 3 Mozhgan Jayez9 Noel Amano1 Behrokh Marzaban Abbasabadi10 Mehdi Aalipoor11 Mary Lucas1 Sara Marzo1 Jana Ilgner1 Robert Patalano12 Patrick Roberts1 Nicole Boivin1 Michael Petraglia13, 14, 15

The Iranian Plateau and the Zagros Mountain chain, located at the crossroads of Africa and Eurasia, occupies a critical geographical position in out of Africa scenarios, sitting astride a major dispersal corridor into southern and central Asia. Yet, the region's role in human population expansions remains under-investigated. Here, we present findings from new excavations at Pebdeh Cave, a site located in the southern zone of the Zagros Mountains. Pebdeh contained a well-defined layer dating to ~42-40,000 years ago (ka), with Levallois elements alongside laminar reduction. This transitional feature in the Zagros was not dated and recorded before and given its similarity to Western and Central Asian industries with respect to chronology and technological features, we define it here as the Zagros Initial Upper Paleolithic (IUP). Though Late Middle Paleolithic and Early Upper Paleolithic technologies have been identified in the Zagros in the time period ranging between 50-40 ka, suggesting the presence of Neanderthals and modern humans in the mountainous region, the overall abrupt and constrained chronology of the IUP at Pebdeh, together with the penecontemporaneous appearance of other Upper Paleolithic sites in the Zagros Mountains, is compatible with a population expansion of Homo sapiens rather than an autochthonous development.

Good paper, but I wish they could get ancient DNA from the Near East during this period of time.

This is what I was talking about with Iran N occupying a position that looks mostly derived from early OoA group with regards to that discussion on an ancient Eurasian tree.

Yes, on Kales thread about ancient West Eurasia I believe.

That means Iran neo minus ANE is the ancestral west asian cluster? Or with ANE?

I was getting minor ANE into Iran after. Not much though. I believe it was around 12%.
