Digital reconstruction of skulls a million years ago suggests that humans may have been different from our ancient ancestors 400,000 years earlier than their minds, a study said Friday.
The findings are based on reconstructions of crushed skulls discovered in China in 1990 and have the potential to address the long-term “chaotic” of human evolution, the researchers said.
But experts who are not involved in the work warn that the findings may raise objections and point to the ongoing uncertainty in the timeline of human evolution.
The skull is marked Yunxian 2, which was previously considered to belong to the pioneer of humanity, known as HOMO ERECTUS.
However, modern reconstruction techniques reveal characteristics closer to species previously thought to exist only in human evolution, including the recently discovered Homo Longi and our own homosexual wise men.
“It changed a lot of ideas,” said Chris Stringer, an anthropologist at the Natural History Museum in London.
He added: “This shows that by a million years ago our ancestors had been divided into different groups, which suggests that human evolution is more complex than before.”
If found correctly, this suggests that there may be other members of early human hormones, including Neanderthals and Homo sapiens, the study said.
Michael Petraglia, director of the Center for Human Evolution Research at Griffith University Australia University, said this is also a long-term hypothesis that early humans dispersed from Africa.
“There is a big change here, and East Asia is now playing a very critical role in human evolution,” he told him. AFP.
“Many problems”
The study, published in the journal Science, uses advanced CT scanning, structured light imaging and virtual reconstruction techniques to model the complete Yunxian 2.
The scientists partially rely on another similar skull to shape its model, and then compared it to more than 100 other specimens.
The results model “shows a unique combination of features,” the study said, and some resemble those of erect people, including those of the leaves.
But other aspects, including its significantly larger brain capacity, are closer to Homo Longi and Homo Sapiens, the researchers said.
“Yunxian 2 may help us solve what is called “chaotic in the middle,” a confusing array of human fossils from 1 million to 300,000 years ago,” Stringer said in a press release.
Many debates about human evolution have been made about human evolution, Petra Laglia said that despite being based on solid work, the findings of the study are “provocative”.
“It sounds, but I think the jury is still there. I think there will be a lot of questions,” he said.
Andy Herries, an archaeologist at Latobu University, said he does not believe in the conclusion, and genetic analysis shows that fossil morphology or shape “is not always a perfect indicator of human evolution.”
“They have this explanation, and I really don’t think they are considering the genetic history of these things we know,” he told him. AFP.
These findings are just the latest in a series of recent studies that complicate our understanding of the original.
Homo Longi, also known as “Dragon Man”, was called the new species by the team including Stringer in 2021 and the “Dragon Man” in 2021.
The authors say their work illustrates the complexity of our shared history.
“Fossils like Yunxian 2 show how much more we have to know about the original,” Stringer said.
