Routes of early people can be unexpected.
Researchers from China think that Homo sapiens may have been many paths in Asia during the late Pleistocene.
The new model determines the unexpected potential route of spread of human culture, reports the online edition of the Chronicle.info with reference for a New time.
When they left Africa, Homo sapiens dispersed across the Asian continent in the late Pleistocene, but it is unknown what routes have been followed by our views. Most models assume that the chain of the Gobi desert and Altai mountains in North and Central Asia formed an impassable barrier on the way to the East, therefore, archaeological research has generally ignored these regions are in favor, apparently, more likely routes further North and South.
In this study, anthropologist Feng Li from the Institute of paleontology and vertebrate paleoanthropology and his colleagues use the software of geographic information systems data along with archaeological and paleoclimate data for the reconstruction of Northern and Central Asia in the late Pleistocene and to determine possible routes of travel.
Their data indicate that the desert and mountain regions were probably impassable in the cold and dry glacial periods, but in warm and more humid interglacial time would be possible, so that people passing through these regions at least three routes of ancient lake and river systems.
The authors warn that these data do not demonstrate certain ways of dispersion of the ancient people and that verification of these results needs to be built more detailed models. However, these models define a specific route that may be good candidates for future archaeological research.
Understanding the timing and tempo of the spread of Homo Sapiens throughout Asia will be crucial to determine how the culture and technology spread and develop, and how our species interacted with our extinct relatives, the Neanderthals and denisovans.

“Our modeling of the available geographical and historical climate data suggests that archaeologists and anthropologists should look for early human presence, migration, and interaction with other hominids in the new parts of Asia that were ignored as a static emptiness. Given the fact that we are learning more and more about the flexibility of our species, it would not be surprising if we found early Homo Sapiens in the middle of modern deserts or mountainous glacial shields throughout Asia,” — noted the authors.
