The earliest humans in Shaanxi or found in China were farthest 2 million 120 thousand years ago.

Original title: great discovery! The earliest humans in Shaanxi or found in China can be traced back to about 1 million 260 thousand to 2 million 120 thousand years ago.

The people of Yuanmou about 1700000 years ago

It has been regarded as the earliest human being in China.

Now

With the publication of the research on Shang Chen ruins in Lantian

This cognition may have to be corrected

Xi'an

The land full of historical memory

It has brought an amazing surprise to mankind.

It was in the morning of today (July 12th)

Science and technology journal Nature (Nature)

A research achievement has been published online

-

Guangzhou Institute of geochemistry, Chinese Academy of Sciences

Research team led by Zhu Zhaoyu

In Yushan Town, Lantian County, Xi'an, Shaanxi, China

An old stone site is found in the new village of Chen Chen

The Shang Chen site

The site has a good continuity.

Sequence of cultural layer of artificial products

It can be traced back to about 1 million 260 thousand to 2 million 120 thousand years ago.

This discovery shows that

Ancient humans probably appeared outside Africa.

Earlier than before

According to the introduction

To date, the earliest known outside Africa.

Evidence from ancient humans came from demenis, Georgia.

The area was found 1 million 850 thousand years ago.

The fossils of the erectus and the tools used

In addition

Found in China and Java in Indonesia

Early paleo human fossils

It can be traced back to 1 million 500 thousand to 1 million 700 thousand years ago

The Zhu Zhaoyu team described in detail the 82 battered stones and 14 unbeaten stones in the S15 to L28 horizon of the early Pleistocene loess paleosol sequence found at the site of the early Pleistocene, including stone core, stone, scraper, apex, drill and hand pick. They are evidence of ancient humans using tools. The author also introduced two stone hammers with striking marks. In addition, in the geological exploration slots in this area, the mandible broken blocks of deer with stone core and stone tools, as well as the skeleton fragments of cattle family (ruminant hoofed mammal) and other animals are found.

Zhu Zhaoyu said:

The age of this old stone culture sequence was determined mainly by the identification of the well developed continuous Loess - paleosol stratigraphic profile and the high density paleomagnetic dating technology. The middle and lower part of this stratigraphic section (S15 to L28) contains 17 layers of artificial products, among which stone products are mainly found in 11 paleosol layers formed in the moist warm climate. In addition, he analyzed the time span of these 17 cultural layers for about 850 thousand years, showing that ancient humans had probably lived on the Chinese Loess Plateau repeatedly (not necessarily continuously) from 2 million 120 thousand to 1 million 260 thousand years ago.

According to the Chinese science newspaper

This time is led by the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences, combined with the Institute of the Institute of earth environment, the Institute of vertebrate and paleontology, the South China Sea Institute of Oceanography, the Institute of Geology and Geophysics, and the Exeter University, England and so on, in Yushan Town, Lantian County, Xi'an, Shaanxi Chen Cun conducted an inspection and geological excavation for about 14 years.

Zhu Zhaoyu:

"Our study confirmed that the earliest relics of ancient human activities at the site of the Shang Dynasty were about 2 million 120 thousand years ago, 270 thousand years earlier than the currently recognized demenis sites in the world."

Wu Yi, doctor of Nanhai Institute of Chinese Academy of Sciences,

There are many clear signs in the geological section of Shang Chen site, and we can see the exact age range. Through field exploration and comparison, the cooperative team established clear loess paleosol sequence and paleomagnetic time series.

Zhu Zhaoyu:

"This study proves that the Loess Plateau is a natural experimental field for the study of the origin and evolution of ancient human beings, and reconsiders the origin, migration, diffusion and evolution of the early human beings. Since no Paleolithic fossils were found in this Paleolithic age, it is not yet possible to identify the race to create these tools.

The distribution of important sites of ancient human remains in the world.
