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.
Each of these species possessed unique morphological characteristics that set them apart. Homo floresiensis, for instance, was remarkably small, earning it the nickname “hobbit” human. Homo luzonensis represented another compact human variant, while Homo longi was characterized by a massive cranium that suggests a different evolutionary trajectory.
The most intriguing aspect of these discoveries is how they challenge our previous understanding of human migration and interaction. Rather than a simple “out of Africa” narrative where one human group replaced all others, the evidence now suggests a much more nuanced story of multiple dispersals, interactions, and genetic exchanges.
The Hualongdong fossils from central-eastern China exemplify this complexity. Dating back approximately 300,000 years, these remains display a mosaic of characteristics that cannot be easily categorized into any single known human lineage. These findings underscore just how intricate human evolution truly was.
“I see the name Juluren not as a replacement for Denisovan, but as a way of referring to a particular group of fossils and their possible place in the network of ancient groups,” writes anthropologist John Hawks, who did not take part in this study, in a statement. “In my opinion, Bae and collaborators have a good case for distinguishing the Chinese fossil record from the fossils from Africa and western Eurasia across this time.”
What makes this research particularly exciting is how it represents a significant leap forward in our understanding of human prehistory. The eastern Asian fossil record has traditionally lagged behind those of Europe and Africa, but now it’s revealing a rich, diverse evolutionary landscape that demands we rethink our previous models.
