studyfinds | Could another group of ancient humans have lived alongside Homo sapiens? A new study suggests that they did, and scientists are starting to piece together the clues of their forgotten past. A researcher from the University of Hawai’i at Manoa is revealing new insights into a group called the Julurens — meaning the “big head” people.
The new research is revolutionizing our understanding of human evolution, particularly in eastern Asia, where scientists have uncovered a far more intricate picture of our ancient past than previously thought.
For decades, researchers believed human evolution followed a relatively straightforward path. The dominant theories suggested either that humans gradually evolved in place across different regions or that a single group from Africa replaced all other human populations. However, the groundbreaking study published in the journal Nature Communications is turning those simplistic models on their head.
Paleoanthropologists Christopher Bae and Xiujie Wu introduce a potentially revolutionary concept: a new human species called Homo juluensis. This group, which may include the mysterious Denisovans — ancient human relatives known primarily through fragmentary DNA evidence — lived approximately 300,000 years ago, hunting and surviving in small groups across eastern Asia before disappearing around 50,000 years ago.
Moreover, they found that eastern Asia was home to multiple distinct human species during the Late Quaternary period, roughly 50,000 to 300,000 years ago. Instead of a linear progression, the human story looks more like a complex, branching network of different populations (including the Julurens) interacting, mixing, and coexisting.
The team identified four human species that existed during this time: Homo floresiensis, a diminutive human found on the Indonesian island of Flores; Homo luzonensis from the Philippines; Homo longi, discovered in China; and the recently named Homo juluensis, which includes fossils from various sites across eastern Asia.
“We did not expect being able to propose a new hominin (human ancestor) species and then to be able to organize the hominin fossils from Asia into different groups. Ultimately, this should help with science communication,” Bae says in a university release.
