A jaw, skull, and leg bones were discovered in Hualongdong, China in 2019. Since then, experts have tried to match the remains to a specific lineage of humans, but they’ve now decided that it may be an entirely new species of hominin from a previously unknown branch. The individual’s face is similar to the anatomically modern human lineage, but the lack of a chin is more similar to the Denisovans. And the limbs, skull cap, and jaw seem to have more primitive traits. Thanks to these similarities and differences, the researchers believe this may be a hybrid between the two branches. Fun fact: Another missing group (or perhaps the same one) that would have lived in the Middle to Late Pleistocene was previously identified by genome studies in Europe and western Asia, but nothing has been found in the fossil record to date. Maybe it’ll turn out that they’re one and the same.
