Center for Archaeological Science, Sichuan University publishes new evidence of tropical rainforest adaptation in South Asia from the Late Pleistocene to the mid-Holocene

In recent years, the adaptation to extreme environments during the dispersal of modern humans has attracted much attention. For example, when and how modern humans expanded to high-altitude, permafrost, desert, and tropical rainforest environments is at the forefront of archaeological debate. Archaeological evidence from Sri Lanka, located in the Indian Ocean, shows that evidence of modern human fossils, microliths, bone tools, and symbolic ornaments appeared around 40,000 years ago, which fully demonstrates that the tropical rainforests of Sri Lanka have special significance for early human foraging patterns. To further understand the continuation and change of the tropical rainforest foraging tradition represented by microliths from the end of the Pleistocene to the early and middle Holocene...

Center for Archaeological Science, Sichuan University publishes new evidence of continuous occupation of Paleolithic cave sites in Southwest China.

Since Marine Isotope Stage 3 (MIS3), significant changes in global climate, population dynamics, and human behavioral patterns have occurred in many regions of the world. With the increasing amount of archaeological evidence, our understanding of human species and technological trajectories in the Late Paleolithic of East Asia has become increasingly complex, while in southwestern China, many key questions remain unclear. Recently, the Center for Archaeological Science, Sichuan University published an article titled "New Evidence of Human Occupation in Southwest China Since 44,800 Years ago" in the international journal Lithic Technology.

The Center for Archaeological Science, Sichuan University, in collaboration with multiple international institutions, is constructing a strontium isotope map of Africa to trace the geographical origins of victims of the transatlantic slave trade.

Population migration has played a significant role in the development of human civilization, shaping global ethnic and cultural patterns. The transatlantic slave trade from the 15th to the 19th centuries was the largest forced migration event in global history, transporting at least 15 million Africans to the Americas and Europe, profoundly altering the ethnic structure and political landscape of Africa, the Americas, and Europe today. Although extensive historical documents record the scale of transportation and port information of the slave trade, the geographical origins and life experiences of enslaved individuals have been difficult to ascertain, which has long been a concern for global archaeologists and historians. Strontium isotope analysis technology (87Sr/86Sr...

Center for Archaeological Science, Sichuan University publishes new perspectives in Land magazine on hunter-gatherers permanently occupying high-altitude areas of the Qinghai-Tibet Plateau.

Over the past decade, when humans permanently occupied the high-altitude areas of the Qinghai-Tibet Plateau and no longer migrated between high and low lands has been the focus of archaeological attention. The mainstream view is that permanent human occupation of the Qinghai-Tibet Plateau became possible only after the introduction of wheat agriculture around 3600 years ago. In response to this major academic question, the Qinghai-Tibet Plateau archaeological team of Sichuan University and the Cultural Relics Research Institute of Tibet Autonomous Region have jointly carried out a series of field archaeological works in the eastern, central, and western parts of the Qinghai-Tibet Plateau in recent years. On the one hand, it reveals the contribution of Neolithic people in the southeastern margin of the Qinghai-Tibet Plateau to permanent occupation at an earlier stage (around 5000 years ago), on the other hand...
