Fossils found in China belong to a previously unknown human ancestor

Recently, a group of researchers from the Chinese Academy of Sciences made an amazing discovery that may change our understanding of human ancestors. The fossils found in Hualundong, China, belong to a hominin that lived about 300,000 years ago. This hominin differs from previously known ancestors of modern humans, such as Neanderthals and Denisovans, and represents a previously unknown human lineage.

The researchers conducted a morphological and geometric evaluation of the fossils and found that the jawbone has unique features such as a triangular lower edge, a distinctive curve, and the absence of a chin. Although this hominin resembles modern humans, it is closer to older species such as Homo erectus than to Homo sapiens.

This discovery supports the theory of the possible coexistence of three lineages in Asia during the Middle Pleistocene: Homo erectus, Denisovan, and a new, as yet unidentified lineage that is one step closer to Homo sapiens. This suggests that the features inherent in modern humans began to appear as early as 300,000 years ago.

However, further research is needed to fully understand the significance of this discovery and its impact on our understanding of human evolution. Scientists plan to compare these fossils with other unidentified hominin bones found in other parts of the world to determine if they belong to the same species.

This discovery also raises the question of the geographic distribution of hominin species in different parts of the globe during the Pleistocene epoch. Therefore, researchers will continue to study this topic to expand our knowledge of human ancestors and their evolution.
