The "Langxian" skull fossil or reflects China's existence of human evolutionary corridors

The Yangtze River Daily Da Wuhan Client September 28 (Reporter Wan Jianhui) The origin and evolution of human beings has been a major scientific proposition about human beings. The discovery of No. 3 Slutia of "Xixian County" one million years ago may help scientists to further expand the "Qinling to Hanshui Basin" as a "human evolution corridor" cognition.

According to CCTV's "News Live Room" on September 28, for the origin and evolution of human beings, the current general consensus of academic circles is "Africa out." The hypothesis believes that human beings originated from African apes. After the evolutionary phase of the southern ancient apes, capable people, and upright people, it has gone out of Africa and spreading around the world at the upright stage and spread to around the world.

Gao Xing, the leader of the archeological expert working group of the Liangzi site and the researcher at the Institute of Chinese Academy of Sciences, believes that human beings originated in Africa. This is just a hypothesis. Some scholars believe that Asia may also be a origin of human beings, but lack of human fossils of human beings 2 million years ago Evidence of culture lacks a series of evidence chains that change from ape to adults, so the academic community basically determines that the original human beings originated in Africa.

The Liangzi site of the academy is located in the Qinling to Hanshui Basin. Qinling area. The Bailong Cave, which has been discovered in Hubei about 500,000 years ago, a late WHO of Huanglong Cave, which is about 100,000 years old, and 153 old stone artifact sites. It is also roughly located on the geographical strip of Qinling to Hanshui.

Gao Xing said that the fossils of the "people in the county" are also in the middle position, so it can constitute a intermediate link from Qinling to Hanshui, a human evolutionary corridor. The sequence of evolution may be a magnificent picture of more materials in the future.

Gao Xing introduced that in general, when the earliest humans evolved from an ancient ape, the amount of brain was small, about 350 ml, similar to the current chimpanzee. In the future, it gradually increased, and in the period of power, once expanded, in the period of upright people, it became significantly expanded than those of the people, like Beijing Ape -Man average of 1088 ml.

The "Langxian People" No. 1 skull and No. 2 skull have a relatively serious deformation. There are very big difficulties in the measurement of brain volume and some anatomical traits. Some people suspected that it was an ancient ape in the south. Thanks to the complete preservation, the No. 3 skull of "Xianxian" is expected to provide more accurate and clear the characteristics of human face skull and brain skull anatomy during this period, as well as major scientific information such as brain volume, evolutionary stage, and regional population characteristics.
