Stone tools are useful. They only had no original person in charge of cutting and suspending meat. But also for anthropologists who continue to migrate and evolve humanity.
In this way, blades appear in a place that has not been built, prior to prediction, sit down and warn.
According to a study by the University of Wollongong in Australia, published in the science journal Nature A paleolithic tool found in a cave south of the south-west China of 80,000 to 170,000 years.
This does not fit.
Understanding how humanity migrates from Africa, Europe and Asia are not in the framework of time.
These are too early.
Neanderthal and Homo Sapiens methods show manufacturing techniques only.
We have known, for a long time, those who inhabited the various species of humans. And a long species of the last decades, Denisovans from Siberia's cave, discovered the first remains, it began to light.
So who – or what – these Chinese artificial realities?
We do not know
Bones are not recovered on the site.
But the discovery has many consequences.
"Our new discovery … suggest that they have been invented locally without any input, or much more than before cultural migration or human migration," wrote the author of the study Conversation. "Chinese documents provide more evidence of the origin and spread of stone technology technologies."
Such discoveries have established understanding of human migration.
The stone tools reveal to their makers. It's not a matter of banging rocks until one of the sharp sharp collapses fall – well, at least not since the first inventors.
As the human minds developed, the complexity of the construction and assembly of their instruments was created.
Archaeologists have defined five types of "tools" of stone tools. Each one is the most important advance and a more complex construction process.

According to the authors of the investigation, the controversial tool called Modu III (Levallois) is sitting in the midst of the technological evolution of stone. Presents useful vermin with pre-prepared stone kernels.
"They are the result of a series of specific steps by crushing a piece of stone, creating similar tools suitable for multiple purposes," writers write.
They have great progress in efficiency, effort and reduced waste.
But where was that style created?
"One of these debates was the way Tool Tools were invented in one place and then spread or independently invented in different locations."
Levallois's oldest stone group was found in Africa 300,000 years ago. And the continuation of the previous evidence suggests that this instrument was only reached in China from 30,000 to 40,000 years ago.

A study by 2273 artifacts from the Ganindong cave in Guanyhou shows 45 examples that match the Levallois style.
"Mod III III tools have been found around 170,000 and now over 80,000 layers, which is used before Modu IV tools (blades), and Levallois was the leading tool in Europe and Africa."
The answer emerged as a result of a lost tribe of humanity, which had long since been in Asia before reaching the modern human Sapiens.
And they can be innovative.
The last meeting suggests a third group isolate Neanderthal and Homo Sapiens. But some of the remains of a finger and other scattered Siberia artifacts, and in China, unusual hybrid skulls, nothing is known.
They are called Denisovans.
"The Levallois nucleus came to China recently thought of as modern humans," said Secretary of State of Washington, Ben Marwick. "Our work reveals the complexity and adaptability of people who are anywhere else around the world, showing the diversity of human experience."
The co-authors of BoL and Hu Yue of Wollongong University can do this.
"For a reason why it has been so difficult to prove the technique in China until today, many Eastern Paleolithic countries may be much smaller than in the West," they say.
"We do not know what the human species did in Guanyindong, who did not find bones, who were similar skills to people living in the West at the same time. It seems independently that Levallois's strategy has been found in China, and at the same time people use it in Europe and Africa your extensive use ".
The authors argue for the best way to find out how to expand and complete new digestive tracts. Many studies were carried out on the museum records and samples of the 1960s and 70s, compared to the fresh soil recovered from the soil.
"Our work shows that ancient people were innovative just nowhere else. East Asian technological innovations can be homegrown and not always in the West," says Marwick.
