Redefining Human History: Scientists Uncover Advanced 1.1 Million-Year-Old Tools in China

Credit: IVPPA new research study from the Nihewan basin of China has actually revealed that hominins who had advanced knapping capabilities equivalent to Mode 2 technological features inhabited East Asia as early as 1.1 million years earlier (Ma), which is 0.3 Ma earlier than the date associated with the first handaxes found in East Asia. One or more of the resulting pieces were then selected as blanks for retouching, with the intending of producing tipped tools with two convergent sides, therefore substantially altering the initial shape of blanks.In addition, patterns of retouching tools like points and borers, which showed standardization of tool shape, were also well recorded in the Cenjiawan assemblage, hence recommending complicated psychological design templates among the Cenjiawan toolmakers.Complexity in Early Pleistocene Tool-MakingThe prepared core technology, standardized predetermined items, and retouching tool shapes, together with the high level of manual precision, fragmented decrease series, long reduction series, and arranged management of raw materials documented in the Cenjiawan assemblage, supply engaging evidence for intricate technical capabilities and thorough planning behaviors among Early Pleistocene hominins in East Asia.The CJW website and Lithology of the CJW profile and matching magnetic polarity time scale. The compelling proof in the Cenjiawan assemblage offers a brand-new viewpoint in understanding the small debitage system in China and may force a reconsideration of current understandings of technological tension in East Asia.The authors argued that the technological functions, rather than the simple presence or absence of particular tool types (e.g., handaxes), need to be the basis for studying Early and Middle Pleistocene assemblages in East Asia.
