A new study has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa some 70,000 ago.
After years of debate, the new study said the human species, who emerged in Africa more than 300,000 years ago and migrated out of the continent 60,000 to 70,000 years ago, have lingered for thousands of years in a geographic hub that spanned Iran, southeast Iraq and northeast Saudi Arabia. These bands of hunter-gatherers then went on to settle all of Asia and Europe starting roughly 45,000 years ago.
Their findings were based on genomic datasets drawn from ancient DNA and modern gene pools, combined with palaeoecological evidence that showed that this region would have represented an ideal habitat, because of its capacity to support a larger population compared to surrounding areas in West Asia.
"Our results provide the first full picture of the whereabouts of the ancestors of all present-day non-Africans in the early phases on the colonization of Eurasia," said molecular anthropologist Luca Pagani of the University of Padova in Italy, senior author of the study published in the journal Nature Communications, opens new tab.
Anthropologist and study co-author Michael Petraglia, director of the Australian Research Centre for Human Evolution at Griffith University, said the study "is a story about us and our history - our goal was to unravel some of the mystery about our evolution and our worldwide dispersal." "The combination of genetic and paleoecological models allowed us to predict the location where early human populations first resided as soon as they exited Africa," Petraglia added.
