Conny Waters – AncientPages.com – The Center Paleolithic interval is usually considered a dynamic period in European and African historical past. But, it has historically been seen as a static part in East Asia. Nevertheless, latest findings from the College of Washington are difficult this view.
Researchers have uncovered a whole Quina technological system on the Longtan web site in southwest China, relationship again roughly 50,000 to 60,000 years. This discovery is critical as a result of whereas Quina expertise was recognized in Europe a few years in the past, it was not beforehand present in East Asia.

“This can be a massive upset to the best way we take into consideration that a part of the world in that time period,” stated Ben Marwick, co-author and UW (College of Washington) professor of archaeology.
“It actually raises the query of, what else had been individuals doing throughout this era that we haven’t discovered but? How is that this going to alter how we take into consideration individuals and human evolution on this space?”
The Center Paleolithic, also referred to as the Center Stone Age, spanned from roughly 300,000 to 40,000 years in the past and is a pivotal period in human evolution. This era marks the emergence and improvement of recent people in Africa. In Eurasia, it’s related to the evolution of archaic human teams like Neanderthals and Denisovans. Opposite to the assumption that China skilled gradual improvement throughout a lot of the Paleolithic period, latest findings problem this notion.
The Quina system found in China has been dated to round 55,000 years in the past, aligning with related European discoveries. This challenges earlier assumptions about stagnation in the course of the Center Paleolithic on this area and enhances our understanding of Homo sapiens, Denisovans, and probably different hominins.
A key function of the Quina system is its distinctive scraper—a stone device characterised by its thickness and asymmetry with a broad sharp edge exhibiting indicators of use and resharpening. Researchers have uncovered a number of such instruments and manufacturing particles. The presence of tiny scratches and chips suggests these instruments had been used for scraping supplies like bones, antlers, or wooden.
Researcher Marwick highlights an essential query: how did this toolkit attain East Asia? Future analysis goals to find out whether or not there was a gradual west-to-east migration or if this expertise emerged independently with out direct contact between teams. Figuring out an archaeological web site with in depth stratification may present insights into device improvement previous Quina expertise’s look.
“We are able to attempt to see in the event that they had been doing one thing related beforehand that Quina appeared to evolve out of,” Marwick stated. “Then we’d say that improvement appears to be extra native — they had been experimenting with totally different types in earlier generations, and so they lastly perfected it. Alternatively, if Quina seems with none signal of experimentation, that means this was transmitted from one other group.”
There are a number of potential the reason why Quina expertise has solely just lately been found in East Asia. In line with Marwick, one purpose is that archaeologists in China are gaining a greater understanding of archaeological practices from different areas, which helps them determine their findings extra precisely. Moreover, accelerating analysis efforts will increase the chance of uncovering rarer artifacts.
“The concept that nothing has modified for such a very long time in East Asia additionally has a decent grip on individuals,” Marwick stated. “They haven’t been contemplating the potential of discovering issues that problem that. Now perhaps there are some students who’re all in favour of questioning these concepts.”
A lot of archaeological discovery depends on luck, Marwick stated, however one purpose for the long run is to uncover human stays within the space.

“That would reply the query of whether or not these instruments are the product of a contemporary human such as you and me,” Marwick stated. “There have by no means been any Neanderthals present in East Asia, however may we discover a Neanderthal? Or, extra seemingly, may we discover a Denisovan, which is one other sort of human ancestor? If we will discover the human stays related to this era, we’d discover one thing shocking — perhaps even a brand new human ancestor that we do not learn about but.”
The research was revealed within the journal Proceedings of the National Academy of Sciences
