Abstract:
A combination of evidence, based on genetic, fossil and archaeological findings, indicates that Homo sapiens spread out of Africa between similar to 70-60 thousand years ago (kya). However, it appears that once outside of Africa, human populations did not expand across all of Eurasia until similar to 45 kya. The geographic whereabouts of these early settlers in the timeframe between similar to 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 theHub 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.
