A groundbreaking new study reveals that ancient human groups inhabited the Mongolian Gobi Desert when it was a lush landscape of lakes and wetlands. The findings, published in PLOS One, push back the timeline of human presence in the region significantly, from approximately 140,000 years ago until around 8,000 years ago.
While the Gobi is known today as a harsh, arid region, researchers say a much wetter climate during the Early Holocene created a favorable environment for early human populations.
A new study published in PLOS One by an international team of archaeologists examined a dried-up lake in the Gobi Desert that was left over from the Ice Age as temperatures rose. They even found a cluster of stone tools — up to 2,700.
The Luulityn Toirom Paleolake provided them with rare evidence of human occupation during this humid phase of the Gobi Desert. This evidence suggests that humans were present much earlier than expected, showing their ability to adapt to desert landscapes during these brief humid periods.
By studying lake sediments, soil layers, and nearby landforms, researchers determined the ancient lake’s size and shape and how the climate changed. They combined all this evidence to glean who lived there, what they did, and how they made these tools.
The study shows that early Homo sapiens were strategic, climate-aware foragers who could thrive on the desert’s edge while they spread to new territories as the global ice melted.
Combining techniques such as geoarchaeology, sedimentology, luminescence dating, and lithic analysis, they discovered that the mountain basin once held a lake in the Pleistocene and Early Holocene, up to 140,000 years ago, according to Archaeology News.
One method worthy of note was optically stimulated luminescence, which helped them to understand how long ago the soil was last exposed to sunlight. This technique uncovered the deepest layers of human activity, which were dated between 8,000 and 13,000 years ago.
Tools that reveal how smart and agile humans were
The 2,726 lithic artifacts recovered suggest that early humans exhibited the ability to think ahead about the tools they crafted with notable skill.
From scraping leather to processing wood and bones, these tools were made from jade and chalcedony, sourced from distant outcrops. This finding shows the remarkable mobility, trade, and foraging territories of these early humans.
As per the study, the tools at site FV92 show that humans “transported raw materials from elsewhere, produced bladelets using structured reduction sequences, and used them for diverse tasks such as scraping, cutting, and processing plant and animal materials.” This reveals a “complex and organized approach to tool production and use” in this region of the Mongolian Gobi Desert.
“It is noteworthy that there are no outcrops of raw materials located in the vicinity of the site,” the study authors explained.
A study that fills a gap in early human history
These early humans were highly mobile and possessed extensive knowledge of their environment. They would have traveled substantial distances to source the materials they used, even to butcher animals and process plants. Archaeologists thus got a snapshot of these early humans during a pivotal moment in history when the climate permitted their dispersal through a warming Gobi Desert.
This was one of the few studies that employed a multidisciplinary approach to understand Early Holocene human activity in the Gobi Desert, revealing how they interacted with the land and adapted to the changing climate. The research focuses on human dispersal after the Ice Age, which was made possible by the rising temperatures, and the strategies they employed to thrive.
“The research is part of comprehensive multidisciplinary projects aiming at reconstructing, among other things, the ways of exploiting the natural environment of the Gobi Desert by prehistoric communities,” the authors concluded in the study.
“The obtained results contribute to filling the gaps in the knowledge about the presence and technological behavior of prehistoric communities in the arid regions of Central Asia.”
