What is the basis for saying that Yuanmou people are human beings?

The Yuanmou people invented the basic tools of labor.

Remains of fire were found at the site.

Hello, glad to answer for you. The concept of Yuanmou people is that everyone is equal. They live in a harsh environment overgrown with trees and beasts.

In addition, the main production tools were rudimentary stone tools, so it was very difficult to obtain food. In this case, the role of the individual is insignificant. They must unite to compensate for the weakness of individual power with the strength of the group.

The members of each group must cooperate with each other, hunt and fish collectively, and work together to defend against the invasion of wild beasts in order to barely survive. Common labour inevitably leads to the destruction of public ownership of the means and products of production, which must also be equally distributed. At that time, people did not have enough food, no clothing, no exploitation and oppression, and because the level of productivity was very low, the raising of the old and weak and children needed to rely on the collective strength of the surplus jujube.

The teeth of the Yuanmou people are large and thick, the lip surface is relatively flat, and the pattern of the tongue surface is very complex. Compared with the incisors of Yuanmou Man and Peking Man, there are some similarities in the size, stoutness, and complexity of the incisors. However, there are also obvious differences between the two, such as the end of the crown of the Yuanmou people is extended and wider, and the base is relatively constricted and slightly triangular.

The crown of the Peking Man is slightly rectangular. Researchers have thus confirmed that Homo erectus should be a new subspecies of Homo erectus. Therefore, it was named after Yuanmou County, where this fossil source was found, and it was named Homo erectus Yuanmou new subspecies (homo

erectus

Yuanmoensis), referred to as Yuanmou Homo erectus, commonly known as Yuanmou Man.

After an in-depth study of the two incisors, it was found that Yuanmou people had a well-developed spade-shaped tongue fossa. The spade-shaped tongue socket is characteristic of the modern race. That is to say, this characteristic of the Yuanmou people gives us a research topic for the origin of a human race.

Later, further research on the tooth morphology of Yuanmou Man, especially through comparative studies with great apes, giant apes, Australopithecus, Peking Man, and Homo sapiens, concluded that Yuanmou Man was closer to Australopithecus and Peking Man. Compared with the teeth of Homo pekingensis, the difference between the teeth of Yuanmou and Peking Man is quite obvious, and the degree of difference is even greater than that of Australopithecus. Due to the fact that they lived much earlier than the Peking Man, according to the complex situation indicated by the existing Homo erectus data, it is proposed to use the upper middle incisors of Yuanmou Man as a representative of the early type of Homo erectus that has been discovered in southern China so far.

The morphological differences with Peking Man reflect the characteristics that they may have had in transition from the slender type of Australopithecus to Homo erectus.

The tooth morphology of Yuanmou Man shows the primitiveness and antiquity of Yuanmou Man, which is the earliest human fossil material found in China so far. It is not surprising that the Yuanmou Man fossils came from the Yunnan region, which was within the range of early human activity.

The production and living conditions of Yuanmou people: boring

1. The Yuanmou people not only used their own tools to engage in hunting and gathering activities, but also learned to use fire to roast and eat the prey they obtained.

2. Yuanmou people live in groups to prevent wild beast attacks and belong to a matriarchal society. Stone tools were used, with men hunting and women collecting. And because the collection is more stable, the status of women is higher.

3. Yuanmou people can use the hammering method to manufacture and repair stone tools, and can make scrapers and pointed tools, and the size of the tools is not large.

Characteristics of Yuanmou people:

Although Yuanmou Man belongs to the category of humans, it still retains the physical characteristics of more apes. For example, the skull is low and flat, the cranial cavity is small, the bone wall is thick, the eyebrow ridge is thick, the jaw is protruding forward, and there is no chin. The teeth are quite different from those of apes, but they are still larger than those of modern humans.

The lower limb bones are similar to those of modern humans, and they can walk upright. They were able to make stone tools, and some were able to use and preserve natural fire.

They live in caves or near river banks, picking plants and hunting animals. China is one of the countries with a large number of late ape-man fossils found in the world, in addition to Peking Man, Lantian Man, Yuanmou Man, in recent years, late ape-man fossils have also been found in Yunxian and Yunxi in Hubei Province and Hexian County in Anhui Province.

Yuanmou people lived 1.7 million years ago.
