Why did the remains of Mexico's seabed break the legend that Indians are Asians?

Early Homo sapiens lived between 250,000 and 40,000 years ago and was close to modern people. But it still has some primitive features, such as developed eyebrow ridge, low forehead, flat nose and prominent jaw. The average brain volume was 1.350 ml.

Although these fossils of early Homo sapiens are found in many places in Asia, Africa and Europe, most of them appear in land or land caves. Therefore, for a long time, human bones found on land have become an important basis for archaeologists to study ancient humans. However, did you know that human bones were found not only on land, but also in an underwater cave in Mexico?

What the hell is going on here? Next, let's take a look.

The oldest human skeleton in the United States was found in an undersea cave in Mexico. It sounds incredible, but it's true. Through radioactive carbon, scientists have dated the bones. After calculation, this female skeleton has a history of more than 13600 years. The researchers named this skeleton? Eva de Nahalen? .

In fact, it is not the first time that ancient human remains have been found in underwater caves. Three human remains were found in underwater caves on the Caribbean coast of Yucatan Peninsula. The discovery of this skeleton provides a new clue to the time when early ancient humans immigrated to America. A research team composed of professionals from the Mexican Museum of the Saarti Desert has made a systematic study of this skeleton in the past four years.

At the same time, the team members also conducted relevant screening near the town of Toulon, Mexico, where the bones were found, hoping to find more bodies. The head of the research team said: At present, they are not sure how these bones found in caves first came to the United States. At the same time, it is not known whether these ancient humans came from the Atlantic coast, tropical jungle or inland areas. But what is certain is that these remains are the oldest human remains found in the United States so far.

Therefore, these remains are of great historical significance for studying the first humans who arrived in America. This has advanced the time for human beings to settle in America for many years, and also provided more favorable evidence for scientists to study the origin of human beings who first moved to America. After analyzing the skull characteristics of the remains, the researchers ruled out the possibility that these ancient humans came from northern Asia. This conclusion can be said to subvert the previous immigration theory in the New World.

Because, at the beginning, people thought that the earliest ancient humans who settled in North America should have come from northern Asia, but now they have mainly sunk? Bering Continental Bridge? Come here and thrive here. Through further analysis of the skull shape, the researchers believe that these bones may be the oldest and most important human bones found in Mexico so far. Judging from the shape of bones and the shape of bones, these bones have the characteristics of ancient Indians.

From this, we can judge and speculate on the age and other information of the owner of this pair of bones. After radiocarbon dating, scientists determined that these ancient humans should have lived11000-14000 years ago. Although these remains were found in caves 0/5m deep at the bottom of the sea/kloc-,research experts believe that when Eva de Nahalon lived, it should be a vast and dry plain, located 60m below the sea level.

The reason why it is Wang Yang now is because it was in 8000? 9000 years ago, changes in climate and temperature caused a large number of polar glaciers to melt, and the melted snow water flowed into the ocean, causing the sea level to rise continuously. It rose by about a few hundred feet, flooding the former plains and the cemetery where these bones were buried. The reason why these precious bones can be preserved in caves is mainly because a large number of stalactites and stalagmites are formed around these bones, thus preventing them from being washed away by water.

In addition, the remains of elephants, giant sloths and other ancient animals were found in these caves.

If the theory obtained through the above research and textual research is finally proved to be accurate, it will be of great reference value for the scientific community to explore the situation of the first batch of ancient humans who settled in America. This discovery also made it possible for humans to cross before? Bering Continental Bridge? The theory that the residence time from Asia to the New World of America was later than 13500 years ago was overthrown, which will also prompt the research topic about when ancient humans began to settle in America to be restarted.

September 20 17, the researchers excavated the fourth ancient human skeleton previously discovered and named it? Chen Hao? . ? Chen Hao? Should be older than Eva de Nahalon. Chan hol's skeleton preserved 10 teeth, which is very complete for ancient human bones. These teeth will also be used as specimens for people to study Chan hol, so as to learn more about people's living habits and eating conditions at that time.

Carlos. Lorenzo, a researcher from Raviglia-Vilkki University in tarragona, believes that the discovery of Mexican remains is of great significance for future related research. If Eva de Nahalon's remains are finally identified as those of ancient humans more than 3000 years ago, it will play a very positive role in studying the history of American colonists. And the related research is in full swing.
