The details

A recent archaeological discovery in East Asia has revealed that hominins with advanced tool-making skills, equivalent to Mode 2 technology, were present in the region over 1.1 million years ago.

This finding challenges previous timelines and perceptions of early technological development in the area.

The hominins were skilled in intentionally breaking slender flakes to be used as blanks for retouching tipped tools.

Unifacially retouched points and borers were also found at the site.

The study, led by Prof. PEI Shuwen and Prof. Ignacio de la Torre, provides key insights into the early dispersals and adaptations of hominins in Eurasia.

Organized flaking techniques were observed in the Cenjiawan refit sets from the Nihewan basin, indicating a standardized operational process.

The prepared core technologies exhibited detailed planning and a deep understanding of flaking mechanisms.

Moreover, the retouched tools showed intentional breakage of slender flakes and standardization of tool shape, suggesting complex mental templates among the toolmakers.

The evidence from the Cenjiawan site provides compelling proof of complex technical abilities and in-depth planning behaviors among Early Pleistocene hominins in East Asia.

The technology documented at the site is similar to Mode 2 technology, challenging the long-held belief that Lower Paleolithic technology in China was simple and homogeneous.

In contrast, a genetic study conducted at Stone Age burial sites in Western Europe revealed that blood relations and kinship were not all-important for hunter-gatherer communities.

Researchers from Uppsala University analyzed biomolecular data from human skeletons at sites like Téviec, Hoedic, and Champigny, dating back to the Mesolithic period.

The study found that distinct families lived together in these communities to avoid inbreeding, indicating that hunter-gatherer groups mixed with other hunter-gatherer groups rather than with Neolithic farmers.

Graves at Téviec and Hoedic contained individuals who were not biologically related, suggesting that strong social bonds existed that were not based on kinship.

Overall, these new findings offer valuable insights into the social dynamics and technological advancements of early human populations in East Asia and Western Europe, shedding light on the complex behaviors and interactions of our ancient ancestors.
