Another major discovery in our country!
In the site of xianren cave in Lushan County, PingdingShan, Henan Province, scientists have found a large number of human fossils, animal fossils, stone tools, etc., which are of great significance for the study of the origin and evolution of modern Chinese humans.
At present, the Site of xianren cave has excavated a number of human teeth and skull fragments, etc., through uranium dating, the smallest age of 2 human skull fragments excavated in the xianren cave site is 32,000 years ago, 12,000 years ago, of which 32,000 years old skull fragments are human frontal bones, and the thickness is within the range of modern human variation.
Many people do not understand the significance of this study, which is important because the human skeletons found in the cave are likely to be the ancestors of Chinese.
However, we know that in our country, many primitive human skeletons have been found, the most famous of which is found on the Keel Mountain in Zhoukoudian, Beijing: the Beijing Ape Man.
Peking apes lived between 700,000 and 200,000 years ago, which also means that they have long come to the land of China. If this is the case, then why is it that the Peking Ape Man is not our ancestor, but the human being found in the Xianren Cave in Henan, about 32,000 years ago, and may be the ancestor of Chinese?
<h1 class="pgc-h-arrow-right" data-track="7" >Why is Peking Ape Man not the ancestor of Chinese? </h1>
To understand why Peking Ape Man is not our ancestor, we also need to know how Peking Ape Man came to china.
According to the current mainstream theory, human beings originated in Africa, as early as 10 million years ago, ancient ancestors of human beings began to live in African forests. However, with the gradual formation of climate change and the formation of the Great Rift Valley in Africa, the ancient ancestors of human beings remained in the East African region to evolve, and the climate in the East African region began to become more and more arid, and the local forests were gradually replaced by savannas.
The large number of forests disappeared, resulting in some apes began to live in the ground, and in the process of living in the field, they learned to eat meat, because digesting meat does not require a longer intestine, so the intestines of these apes began to shorten, and the shortening of the intestines invisibly saved a lot of energy. In addition, compared to plants, meat energy is higher, so that a lot of energy is saved, and this energy is also used to develop brain capacity, so the brain capacity of ancient humans is getting larger and larger.
About 1.8 million years ago, the first member of the human family, the Noh, was born. Capable people have begun to learn to use and make rough tools.
After the Noh, a kind of man evolved on Earth: Homo erectus, and Homo erectus learned to use fire. At this time, due to global climate change, some Homo erectus began to go out of Africa and reach all over the world, among which those who arrived in Beijing, China, were called "Beijing Ape Man".
Although Peking Ape Man learned to use fire, Peking Ape Man belongs to Homo erectus, while we modern humans belong to Homo sapiens, and the two are not the same species, so Peking Ape Man is not our direct ancestor. It's just that they came to live in china one step ahead of our ancestors, but in the process of later evolution, they gradually became extinct because they were difficult to adapt to the environment.
<h1 class="pgc-h-arrow-right" data-track="14" > 32,000-year-old modern human fossils</h1>
The reason why it is believed that the 32,000-year-old human remains unearthed in the Xianren Cave in Henan may be our ancestors, mainly because the human remains belong to early modern human fossils.
After Homo erectus left Africa, a portion of the hominids remained in East Africa and evolved, including our ancestors.
About 200,000 years ago, early Homo sapiens appeared, and about 100,000 years ago, the first Homo sapiens began to leave Africa, but these people did not leave offspring, and disappeared.
About 65,000 years ago, the second group of Homo sapiens came out of Africa, and this time Homo sapiens not only succeeded in leaving Africa, but also spread around the world, including the regions where we live.
According to experts, about 30,000 years ago to 50,000 years ago, it is a critical period for the spread of modern humans and the emergence and development of behavior, which is the discovery of human fossils 32,000 years ago, which not only fills the gap in human evolution at this stage in the Central Plains, but also directly proves the evidence of early human life in china's Central Plains.
In the site of the Immortal Cave, in addition to the discovery of ancient human fossils, there are a large number of animal fossils, stone products, etc., a total of 287 animal fossil specimens can be identified, including Przewalski's gazelle, brown bear, red deer, porcupine, wolf, roe deer, musk and rodent small mammals, etc., and these animals lived and lived like ancient humans, all 30,000-40,000 years ago.
This means that these animals are likely to be the food of ancient humans, and they brought the food obtained from hunting here to eat, which is of great value for studying the diet of ancient humans and reconstructing the ancient ecological structure, which is also conducive to helping us understand the changes in the ecological environment in the central plains in ancient times.
Therefore, we can say that the ruins of the Immortal Cave are a treasure for all mankind!
