A skull maintained almost completely for more than 140,000 years in northeastern China represents a new species of ancient people more closely related to us than even Neanderthals– and might fundamentally change our understanding of human development, researchers revealed on Friday.
It came from a large-brained male in his 50s with deep-set eyes and thick brow ridges. Though his face was large, it had flat, low cheekbones that made him resemble modern individuals more carefully than other extinct members of the human ancestral tree.
The research group has actually connected the specimen to other Chinese fossil findings and is calling the species Homo longi or “Dragon Man,” a recommendation to the region where it was found.
The Harbin cranium was initially found in 1933 in the city of the same name but was reportedly concealed in a well for 85 years to protect it from the Japanese army.
It was later dug up and handed to Ji Qiang, a professor at Hebei GEO University, in 2018.
” On our analyses, the Harbin group is more carefully connected to Homo sapiens than the Neanderthals are– that is, Harbin shared a more recent common ancestor with us than the Neanderthals did,” co-author Chris Stringer of the Natural History Museum, London informed AFP.
Sister species
This, he stated, would make Dragon Man our “sis species” and a more detailed forefather of modern-day guy than the Neanderthals.
The findings were published in 3 documents in the journal The Innovation. The skull dates back at least 146,000 years, putting it in the Middle Pleistocene.
” While it shows normal archaic human features, the Harbin cranium presents a mosaic combination of primitive and derived characters setting itself apart from all the other previously called Homo types,” said Ji, who led the research study.
The name is originated from Long Jiang, which literally means “Dragon River.”.
Dragon Man most likely lived in a forested floodplain environment as part of a small neighborhood.
” This population would have been hunter-gatherers, living off the land,” stated Stringer. “From the winter season temperatures in Harbin today, it looks like they were managing even harsher cold than the Neanderthals.”.
Offered the place where the skull was found along with the large-sized male it suggests, the team believe Homo longi may have been well adjusted for harsh environments and would have been able to distribute throughout Asia.

Scientist first studied the cranium, identifying more than 600 characteristics they fed into a computer system design that ran millions of simulations to determine the evolutionary history and relationships between different species.
” These recommend that Harbin and some other fossils from China form a 3rd lineage of later people along with the Neanderthals and Homo sapiens,” explained Stringer.
The other findings consist of a fossilised skull from the Chinese province of Dali that is believed to be 200,000 years of ages and was discovered in 1978, and a jaw found in Tibet going back 160,000 years ago.
Stringer described that his Chinese coworkers had actually chosen upon the name Homo longi, which he called a “fantastic name,” however stated he would have been equally pleased to describe the species as Homo Daliensis, which was formerly utilized for the Dali cranium.
More than 100,000 years back, a number of human species existed together throughout Eurasia and Africa, including our own, Neanderthals and Denisovans, a just recently discovered sis species to Neanderthals. “Dragon guy” might now be included to that list.
An alternative description is that Homo longi and Denisovans remain in reality one and the exact same. Fossils up until now credited to Denisovans include bones and teeth however not a full skull, so researchers are not sure what they appeared like.
Denisovans and neanderthals were genetically closer to each other than to Sapiens, while the new research study suggests Homo longi were more anatomically comparable to us than Neanderthals.
The sticking around unpredictability may therefore require future hereditary sequencing to assist clear up.
