Stone tools in China point to the disappearance of human race



[ad_1]

Stone tools are useful. It's not just for the original producers when it comes to cooking meats and skirts. But at the same time they are watching the migration and evolution of humanity for anthropologists.

Hence, when an oddly constructed set of knives emerges in an unexpectedly long time, they sit and draw attention.

According to a study published in the science journal in Australia's Wollongong University Nature A cluster of Paleolithic tools in a cave in southwestern China is between 80,000 and 170,000 years old.

This is not appropriate.

The understanding of how humanity migrates from Africa to Europe and from Asia to Europe does not fit within this timeframe.

They're too early.

Only half of those times show production techniques in the Neanderthal and Homo Sapiens methods around the world.

We know a few different types of people living with each other for a long time. And in recent years, after a cave in Siberia, they found a long lost species – the first one they found, Denisova.

And who made these strange Chinese works?

We do not know.

No bones were recovered from the site.

But the find has many meanings.

Or Our new discovery ler says that they can be invented locally without entering from other places, or they have come from previous cultural transfers or human immigration “. Talk. . These Chinese works offer a piece of evidence that changes our thinking about the origin and spread of new stone tools technologies. En

Some such finds distract the established understanding of human migration.

SIGNS OF STONES

Stone tools show a lot about their makers. Not a matter of multiplying rocks until only a few sharp chips have fallen, at least since the first inventors.

As human minds evolve, so is their complexity and complexity.

Archaeologists have identified five different ”mode“ stone tools. Each represents a significant advance in terms of previous arrivals and a more complex construction process.

RELATED: Is there evidence of civilization before humanity?

According to the authors of the study, sitting in the middle of this stone technology is a controversial group called the Mod III (Levallois) tools. It contains striking, useful stamps from a previously prepared stone core.

”These are the result of very specific steps to sculpt a piece of stone to create similar sized tools for shaping for various purposes, Yazar the authors said.

They represent a big step in terms of efficiency – both in terms of effort and reduced waste.

But where did this style come from?

”One of these discussions is whether Mod III vehicles were invented in one place or if they were invented in different places.“

The oldest group of Levallois stones was found in Africa, some 300,000 years ago. And the evidence of previous evidence shows that this kind of team construction came in only 30,000 to 40,000 years ago in China.

However, an analysis of 2273 works recovered from Guanyindong Cave in Guizhou Province showed 45 examples of Levallois style.

Uk We found Mod III vehicles in layers that lasted approximately 170,000 and 80,000 years ago. This reveals them before the Mod IV tools (knives) and also as the main tools used by Levallois in Europe and Africa. "

OTHER HUMAN

The answer can be attributed to evidence of a human missing tribe who may have been well established in Asia long before modern Homo Sapiens arrived.

And they can be innovative.

Recent findings show a third group isolated from Neanderthals and Homo Sapiens. However, with the exception of some of the remains of a finger and some scattered artifacts in Siberia, as well as some unusual hybrid skulls in China, nothing is known about them.

They are called Denisovans.

Çin Levallois cores were thought to have come from China with relatively recent modern people, di says Ben Marwick, co-author of Washington University. Or Our work reveals the complexity and compatibility of people who are equivalent in other parts of the world. Shows the diversity of human experience. "

The authors, Bo Li and Hu Yue from Wollongong University, this one step further.

Insanlar One reason why it is so difficult to find evidence of the technique in China so far is that the number of people in East Asia in the Paleolithic era can be much smaller than in the West. “

Araç We don't know what kind of people the vehicles in Guanyindong belong to because we couldn't find any bones. Whoever it was, they also had similar skills to people living in the West. Levallois in China independently explored his strategy, while at the same time using people intensively in Europe and Africa. "

The authors argue that it is the best way to go back to the new digs and make them happen. Most of his works have been completed according to the museum records and samples made in the 1960s and 70s and compared with the fresh soil samples collected from the field.

Iyor Our work shows that old people have as much innovation as they are there. Technological innovations in East Asia can be grown at home and not always available from the West, # says Marwick.
