Research: The culture and ancient traditions of Neanderthals and early modern humans have existed for more than 654.38 million years.

According to foreign media reports, it is estimated that Achery people died out as early as 200,000 years ago, but new findings show that it may have lasted longer and overlapped with the more advanced technology created by Neanderthals and early modern people for more than 654.38 million+years.

By Dr. alastair Key (University of Kent), Dr. David Roberts (University of Kent) and Ivan Jarry? This discovery was made by a research team led by Dr. (Biological Center of Czech Academy of Sciences) when studying stone records in different parts of the world. Archaeologists and experts in cultural relics protection have been able to reconstruct the end of the Achery era and redraw archaeological records by using new statistical techniques in archaeological science.

In the past, people thought that the early design of stone tools in Achery changed rapidly with the more advanced Le valois technology created by Heidelberg people (the same ancestor of modern people and Neanderthals) and early modern people and Neanderthals. However, this study provides a new clue for the transition between the two technologies, indicating that there is a lot of overlap between the two technologies.

Asheli stone tool technology is the oldest cultural tradition of early human beings. Hand axe and machete originated in East Africa 6.5438+0.75 million years ago. They are a kind of stone tools representing this period, and were later used by different kinds of early humans in Africa, Europe and Asia. Prior to this, it is generally believed that the Asheli period ended 3-1.5 million years ago. However, there is no specific date in the record, and its extinction time has been controversial. Research teams in Kent and Czech Republic found that this tradition may end at different times around the world-from sub-Saharan Africa 6.5438+0.7 million years ago to Asia 57,000 years ago.

In order to know when the Stone Age ended in Achery, the research team collected information from different archaeological sites around the world to find the latest known stone tool assemblage. A statistical technique called best linear estimation, which is usually used in conservation research of species extinction, is used to predict how long the stone tool tradition will last after the latest known location. In fact, this technology can model undiscovered archaeological records.

Dr. Ji, a paleolithic archaeologist and the main author of this study, said: "The earliest archaeological record is always an incomplete picture of early human behavior, so we know that the youngest known Asheli site is unlikely to truly represent the final example of these technologies." By reconstructing these missing archaeological records, this technology not only allows us to know more accurately when this tradition will end, but also points out the direction for us to discover new archaeological discoveries in the future. "

Dr Roberts added: "This technology was originally studied by a colleague and me, because the last time a species appeared is unlikely to be the time when it really became extinct. It is exciting to see it applied to a new environment. "

According to reports, this new paper, entitled "Simulating the end of Ashley at the global and continental levels and proposing to extend the permanence to the Middle Ages", has been published in Humanities & Social Sciences Newsletter.
