Oldest Human Fossils Outside Africa, found in Zihren Cave (China)

A human jawbone fossil found by palaentolog Zihren Cave, China. The fossil was actually discovered in 2007, but a new publication this year. The fossil has a modern human traits, such as a protruding chin.

Although the structure of the jaws show characteristics of modern humans, but the age of the fossils were found is 60,000 years older than the oldest Homo sapiens in China. "The fossils were discovered it was the oldest human fossils found outside the African continent," said Erik Trinkaus, an anthropologist from Washington University, USA.

Among the research results, the researchers suspect that in his time, humans are now found in the fossil is never interact and even mating with other human species, such as Homo neanderthalensis. Erik said, and was previously no studies that 1 to 4 percent of human genes are genes of Homo neanderthalensis.

A more scientific analysis, discovery of modern human fossils in China is disturbing theories about the span of human migration out of Africa that had been believed. As known, popular theory says that humans began to develop in the African Continent. While humans began migrating out of Africa to expand its territory since 60,000 years ago.

"Until now, genetic evidence supports the theory about human timeframe 'Out of Africa'. However, this invention provides a new challenge on the theory," said Christopher Bae, an anthropologist from the University of Hawaii who was not involved in this research.

Another scientist, John Hawks of the University of Wisconsin, also revealed that the fossil jaw found in China are the traits of modern humans. "If it is proven true, then we must think again about our views. In theory, the view of researchers is correct, just need to proof it," he said.

In addition, the researchers said, the results of this research also revealed that the kind of man who found this fossil has come to China before they behave like human beings. It was indicated from the lack of archaeological traces, such as a picture of an animal or human that is found in China before 30,000 years ago.
