When researchers digitally reconstructed a crushed skull unearthed in China, they made a surprising discovery, revealing features that could potentially alter the story of our beginnings.
Researchers believe the skull, known as Yunxian 2, is approximately one million years old. This finding suggests that the lineages leading to modern humans and their relatives may have existed at least half a million years earlier than previously believed.
The “Muddle in the Middle”
The stretch of time between one million and 300,000 years ago has presented challenges for scientists studying human evolution. Fossils from this era are often incomplete or difficult to classify. This ambiguity leaves questions about whether they represent early examples of Homo erectus, the first Neanderthals, or ancestors of Homo sapiens. These uncertainties have led scientists to refer to this era as the “Muddle in the Middle.”
The Yunxian 2 skull was first discovered in Hubei Province, China, in 1990. It was initially classified as Homo erectus, the large-brained ancestor believed to have dominated that era. However, new technologies have since let researchers examine the skull more closely, and the latest results challenge this earlier classification.
Digital Reconstruction and Analysis
A recent study published in Science details the process of reconstructing this fossil. The reconstruction was performed by an international research team, led by Xijun Ni of Fudan University and Chris Stringer of the Natural History Museum in London. The team utilized advanced CT scanning, structured light imaging, and 3D reconstruction techniques to digitally restore the Yunxian 2 skull.
These advanced techniques were required to understand the structure of the skull, which had been severely damaged. The resulting digital model was then compared with over 100 other human fossils to assess its features and evolutionary significance.
The analysis revealed that Yunxian 2 contains a combination of features not typically seen together. Certain characteristics, such as a projecting lower face, are consistent with Homo erectus. Other aspects, including a larger braincase and more modern facial proportions, are more aligned with Homo longi. Some of these traits are also shared by early Homo sapiens.
Stringer, who co-led the analysis, described the work as transformative. “It suggests that by one million years ago, our ancestors had already split into distinct groups, pointing to a much earlier and more complex human evolutionary split than previously believed,” he said. “This changes a lot of thinking.”
A More Complex Family Tree
If these findings are accurate, they would push back the emergence of the large-brained human species by at least 400,000 years. This revised timeline suggests that Homo sapiens, Neanderthals, and Homo longi may have coexisted on the planet for extended periods. This also raises the possibility that these groups interbred during that timeframe.
“Human evolution is like a tree,” Ni said. “This tree included several branches, and there were three major branches that are closely related, and they may have some interbreeding to each other, and they coexisted for almost one million years.”
“So this is an unbelievable result,” Ni added.
The discovery also raises questions about the origin of our species and the significance of Asia in human evolution. While the prevailing view is that Homo sapiens originated in Africa around 300,000 years ago, the Yunxian 2 reconstruction and other million-year-old fossils found in Eurasia indicate that Asia may have played a much larger and more direct role in shaping our evolutionary lineage than previously assumed.
Michael Petraglia, director of Griffith University’s Australian Research Center for Human Evolution, called the findings “provocative.” He also noted that they muddy the waters of long-standing ideas that early humans dispersed exclusively from Africa.
Controversy and Caution
Not all experts are convinced. Aylwyn Scally, a geneticist at the University of Cambridge, pointed out that there are notable uncertainties when interpreting both fossil shapes and genetic data. “One has to be particularly tentative about the timing estimates, because those are very difficult to do, regardless of what evidence you’re looking at,” he said. “Even with the largest amount of genetic data, it is very difficult to place a time when these populations may have co-existed to within 100,000 years, or even more.”
Other researchers, including La Trobe University archaeologist Andy Herries, point out that relying solely on skull features can be unreliable when determining evolutionary relationships. While genetic analysis of Yunxian 2 would provide more definitive evidence, DNA is seldom preserved in fossils of this age.
Even Stringer noted that the picture remains incomplete. He emphasized the importance of including fossils from Africa and Europe of comparable age in future analyses, as it is possible that multiple regions contributed to the intricate history of human evolution.
Yunxian 2 has already become a focal point in the study of human origins. If the conclusions hold, the fossil suggests that the human family tree began branching a million years ago, adding new depth to the long-contested “Muddle in the Middle.”

Out of Africa is a politically correct lie, that is perfect for the DEI/politically correct times that we live in. Mankind also originated in Eastern Asia. The cold parts of it, warm parts too. This is my take.
The dating on all these ancient human finds is all over the place. Scientists are winging it. No one is going to give grant money to a confused scientist who says, “We don’t know yet”. This farce is similar to the billions in grant money going to so called climate scientists.
Hominid migrations went both ways. Out of and INTO Africa.
Sorta depends on where you draw the “human” line, doesn’t it?
We are a lustful species.
A LOT of these carbon dating improbably large numbers turn out to be errors, that subsequently are downgraded by a LOT.
Heh-Lin Thomas?
If its a million years old its a fossil not a bone. So we don’t know the DNA. And it may very well not be a human (or Homo Erectus) at all. I think we need a lot more than these fragments to determine that this fits on our family tree and where. Africa does have Lucy who is about three million years old and they have most of a full skeleton.
Ugh Li Ho
Anything to counter God’s statement of His creating human began with Adam & Eve as recorded in the Bible.
Believing humans evolved from a single cell in the primordial swamp is insanely stupid.
Sum Ting Old
Uder Ting Way Old
So I’m not African-American but Asian-American now?
No, “climate science” is very different. There is huge money to be made in that space, not so much in archeology.
🧬
That would be insanely stupid if it were true, but it’s not.
Anatomically correct humans were around 300,000 or more years ago. Just swing in the trees and lurking in caves for 290,000 years. If anyone believes that they are fools.
Yep, it is obvious to anyone that there were 3 different branches of humanity that form the 3 basic races or breeds if you prefer (black, white, and asian)
All other races are just a simple mixture of those three.
I think this story is a crock.
