Anonymous users2024-02-08An in-depth analysis of fossils has allowed the history of modern humans to go back 10,000 years. Scientists have concluded about fossils unearthed in Ethiopia——— some fossilized bones were unearthed in Ethiopia about 40 years ago.
After years of research, scientists have finally concluded that this may be the earliest known fossil of a modern human race, dating back 10,000 years, 350,000 years earlier than the original known time. Fossils were unearthed in 1967 near the Omo River in southwestern Ethiopia. One of the fossils, known to archaeologists as "Omo 1", contains part of a fossilized skull and a body skeleton; On the "Omo 2" excavated from the other side of the river, a larger skull was found, but no fossilized bones were found.
Unfortunately, based on the fossils found, archaeologists were unable to put together a complete face. Although Omo 2 appears more primitive than Omo 1, scientists have classified the two fossils as "Homo sapiens" (the scientific name for modern humans) and estimated them to be around 130,000 years old. After research in recent years, scientists have finally determined that the age of these fossilized bones is 1.95 million years.
Conclusion After the excavation of the two fossils, there has been a lot of academic controversy in the archaeological field. Some experts insist that the two fossils are not from the same period, as "Omo 1" is clearly more "modern" than "Omo 2". In the latest issue of the British journal Nature published on the 17th, a scientific research team composed of three geologists from Australia and the United States unified their understanding.
A team led by Ian McDougall of the Australian National University's Institute of Earth Sciences has proposed that they use argon isotope determination to determine the age of fossil deposits by the degree of isotope attenuation. The results showed that the two fossils came from the same sedimentary rock layer, which is located 100 meters deep underground across the Omo River. The scientists finally concluded that "Omo 1" and "Omo 2" both lived 195000 years ago, with a positive and negative error of 5,000 years, so "'Omo 1' and 'Omo 2' are the oldest modern human fossils ever discovered".
As for "Omo 2", it is older because the bones come from different but overlapping ethnic groups. History On the question of the origin of mankind, there is the origin of the human family and the origin of Homo sapiens. Judging from the current archaeological results, there is not much debate in the academic community about 7 million to 5 million years ago that the common ancestor of the family originated in Africa.
However, the "African origin theory" lacks crucial fossil evidence. For a long time, scientists have not been able to find a relatively complete and well-dated Homo sapiens fossil at the critical stage of the origin of Homo sapiens in Africa——— from 300,000 to 100,000 years ago. It was not until 1997 that the Hetu fossil was unearthed.
The dating of Omo's fossils undoubtedly provides new evidence for the "African origin theory".

Go, known as Yi in ancient China, can be said to be the originator of chess in the entire ancient chess category, and has a history of more than 4,000 years. According to the Shiben, Go was created by Yao. Jin Zhanghua also said in the "Naturalist": >>>More
It was the Houjin created by Nurhachi, because the Ming Dynasty had not been destroyed, so the Ming Dynasty was the real dynasty at that time, and the Houjin could only be regarded as a vassal state or something, and the Houjin had not yet entered the customs at that time, so it was called the Houjin. The Qing country was created by Shunzhi, and after Wu Sangui surrendered, Dolgon took Shunzhi into the customs, so the country name is Qing. It was the Qing Dynasty (that is, the Later Jin) that Nurhachi and Huang Taiji fought before entering the customs. >>>More
Coal is a solid combustible organic rock, which is mainly formed by biochemical action of plant remains, buried and then transformed by geological processes. Commonly known as coal. The formation of coal is transformed into peat or saprolite by peatization or saprolite by plant remains accumulated in stagnant water bodies at normal temperature and pressure on the surface; After peat or saprolite is buried, it sinks to the deep underground due to the decline of the basin basement, and is transformed into lignite by diagenesis. When the temperature and pressure gradually increase, it is transformed into bituminous coal to anthracite through metamorphism. >>>More
