Teeth Discovered in China Show that Modern Humans Left Africa at Least 30,000 Years Earlier than Previously Thought
A team of Chinese and Spanish researchers say that at least 80,000 years ago there were Homo sapiens, with a completely modern appearance, already living in Asia. This assertion is based on the thorough analysis carried out on 47 teeth which belonged to at least 13 individuals.
The newspaper El Mundo reports that the teeth were recovered in the Fuyan Cave, located in the south of China, in Daoxian . The study was presented in the journal Nature and shows that modern humans lived in Asia long before they arrived in Europe and the Eastern Mediterranean: between 30,000 to 70,000 years before, in fact.
"The Daoxian teeth are the earliest evidence of modern humans out of Africa that we have today ," Maria Martinon-Torres , a researcher at the University College London , member of the research team at Atapuerca since 1998 and co-author of the study, told El Mundo . She also said:
"The majority of the scientific community has supported the hypothesis that modern humans left Africa only around 50,000 years ago, which is known as the "Recent Out of Africa" hypothesis. Other previous evidence on the possibility of Homo sapiens in Asia before 50,000 years ago has not been accepted unanimously, either because it could not be ascertained that they were part of our species or because their stratigraphic context, i.e. exact origin and dating, creating doubts. With our study of the Daoxian remains we have broken the quarantine to which these assumptions were subject ."

Another of the lead researchers, Liu Wu of China's Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), told CNN “The fossils reveal that 80,000 years ago, the first modern humans appeared somewhere in southern China. We believe that southern China probably was a central area for modern evolution."
For his part, Jose Maria Bermudez de Castro , co-author of the study with Martinon-Torres and co-director of the Atapuerca site, explained that:
"Modern humans arrived in Europe some 40,000 years ago and in China and Australia there is previous evidence for their existence between 45,000 and 50,000 years ago. So a minimum figure of 80,000 years ago for the Fuyan Cave is a major leap. It also confirms the hypothesis about the departure of Homo sapiens out of Africa much earlier than previously thought and their passage via the Bab el-Mandeb Strait, on the Horn of Africa ."

Although remains of Homo sapiens from 90,000 years ago have been found at the sites of Skhul and Qafzeh caves in Israel, the fact is that these individuals still retain some archaic or primitive features – something not present in the Daoxian fossils.
"This article forces the scientific community to rearrange all the information on how, when and perhaps why this first expansion outside of Africa took place. In addition, there is no doubt that new projects will be launched in China and perhaps in other regions of Southeast Asia to confirm the antiquity of our study ," Jose Maria Bermudez de Castro told El Mundo .
The teeth were discovered with a wide variety of fossils of other mammals, both extinct and existent. According to Maria Martinon-Torres the evidence for the dating came about because: “All the fossils have been sealed in a calcitic floor, which is like a gravestone, sealing them off. So the teeth have to be older than that layer. Above that are stalagmites that have been dated using uranium series to 80,000 years.”
The maximum age of the teeth has been dated to 120,000 years ago. This earlier date has been inferred by the wildlife that was found near the human remains – which is typical of the Upper Pleistocene period.
Neanderthals and Modern Humans
Martinon-Torres mused that:
"It is interesting to think that while modern humans were in Asia about 100,000 years ago, they were not able to get into Europe until only 40,000 years ago . We think that maybe Neanderthals were an additional barrier to a tropical species (Homo sapiens) that was not ready for the hostile climate - even though the Neanderthals were able to survive there for hundreds of thousands of years. We always thought that the entry of Homo sapiens caused the Neanderthal extinction. But perhaps we should also be open to the possibility that they only were able to open the way when Neanderthals began to decline, after such a long isolation in a difficult location. It was only when Neanderthals were exhausted demographically and genetically weaker that Homo sapiens had the opportunity to enter. "

Bermudez de Castro and Martinon-Torres have been collaborating for years with the IVPP in Beijing . The Spanish investigators visited the site of Daoxian a year ago and examined the original teeth. There they were able to see that the conditions of the cave were not ideal, so the more resistant skeletal human and animal remains are the only ones that endured the long passage of time.

Myself, if I weren't a white dude of european ancestry, I’d be semi pissed if the powers that be declared caucasion skulls were indicative of modern man, and varience was less. While on every campus on earth, pretty much every skull type is represented.
Not to mention the scary implications of getting in step with the likes of evolutionists like Hitler and Stalin…
It’s pushed too hard with nothing what so ever to back it up, and woe to the scientist that tries to publish data that screws with the religion of the state.
Why is the roundest head possible used for comparison? Many less sensationalist comparisons could be made. Even a cornfed hard working slavic farmer or an Aussie Aboriginal both homo sapien sapien would give a more proper time/evolutionary comparison without touting extreme differences to push a dogmatic belief on us.
Much if not all of the mainstream theory(ies) of human origin doesn’t match up with observations. More and more the out of Africa theory of human orgins seems wrong.
I think we will never get it right, because massive worldwide catastrophes have destroyed most of the evidence of the past.
Rather than thinking of humans as “modern,” or “modern with archaic features,” or other variations, what about thinking of the fossil records as various mutations from a prior unknown ancestor.
The genetic evidence shows that humans almost died out completely not that long ago, leaving only about 2000 breeding humans. It follows that the survivors of these 2000 survived mostly as mutants, as such a small genetic pool would result in a lot of mutations.
And over tens of thousands of years, we the descendants of these 2000 have sort of stabilized our mutations, but not completely. Birth defects occur by the tens of millions every year, of all sorts. People have massive variations, from tiny brains to giant ones, tiny bodies to giant ones, colors of all shades, head shapes of all types, body shapes of all types, etc.
I think these represent continuing mutations and genetic viability problems.
