Homo sapiens, the ancestor of mankind, was mixed with many human races, and the confusing ghost ancestor has always been a mystery

Who are the ancestors of human beings?

Paleoanthropologists have been working to study where modern humans came from and who the ancestors of human beings were. Thanks to the rapid development of genetic technology and the rapid progress of science, we can now have a glimpse of the secrets of human ancestors. After all, however, when the truth is thought to be known, more and more mysteries are discovered.

Paleoanthropologists and geneticists have used DNA testing technology to build a huge human gene pool of all the various human groups that exist today. Finally, through comparison, scientists found that the ancestors of modern humans were the same species: Homo sapiens.

Homo sapiens migrate from Africa to the rest of the world

Although psychologically we are willing to believe that the ancestors of Asians originated in Asia, in fact, according to the research of scientists, the ancestors of modern humans actually originated from the African continent, and then migrated from Africa to all over the world.

Before Homo sapiens, the ancestors of mankind, left Africa, many different races had already left Africa and spread all over the world.

The first people to migrate out of Africa included Homo erectus, Heidelberger, etc. They spread to Eurasia and slowly evolved into the later Hobbits and Neanderthals.

Homo sapiens have mixed with various human races

When Homo sapiens, the ancestors of human beings, came to the Eurasian continent, they found that there were already many human races living here, so the various human races carried out mixed breeding here.

Today, apart from people in Africa and other places, about 4% to 5% of the genes in other peoples around the world come from Neanderthals.

In a series of archaeological activities in the later period, paleoanthropologists discovered a fossil of two teeth of an unknown ape man in a natural cave in Siberia. and named it Denisovans.

The only surviving species: Homo sapiens

Scientists have found that about 6% of the genes of modern humans are derived from Denisovans, especially humans in Southeast Asia such as Thailand and Myanmar, who carry a relatively high proportion of Denisovan genes in their bodies.

The people in the Melanesian Islands in the southwest of the Pacific Ocean are called Melanesians. After comparing the DNA of Melanesians, scientists found that they have the highest proportion of Denisovan genes in the world. modern humans.

Although different races and human ancestors, Homo sapiens, have had mixed-breed reproduction, all other human races except Homo sapiens have all gone extinct without exception, and only Homo sapiens has survived tenaciously to this day.

ghost ancestors

With the development of science, paleoanthropologists have discovered that Homo sapiens not only mixed with Denisovans and Neanderthals, but also mixed with a mysterious "ghost race" that had never been discovered before. . This "ghost race" also slowly began to surface.

There are a small number of Melanesians living on the Andaman Islands in Southeast Asia, our neighbors. After scientists extracted DNA samples from them, they unexpectedly found that their entire DNA was not the same as the human DNA we know now. match.

This piece of DNA does not belong to Homo sapiens, nor Neanderthals or Denisovans, which shows that there is still a kind of "ghost ancestor" that has never been understood in modern humans.

Is the "ghost ancestor" Homo erectus?

Scientists also believe that in the process of human migration, the human race in Southeast Asia is indeed very complex, and this may be possible, but the scientific community has not found any clues about the "ghost race", which also makes this Discovery becomes confusing.

Some scientists also believe that this "ghost race" may be Homo erectus, and the well-known Peking Man is a type of Homo erectus. These Homo erectus may have appeared in Southeast Asia and have survived for a long time, and are similar to our ancestors. People have met.

Homo erectus may have reproductive isolation from Homo sapiens, so it is still a mystery whether it is a ghost ancestor

But so far, there are very few fossils about Homo erectus, and a considerable number of scientists believe that Homo erectus and Homo sapiens have reproductive isolation, and there is no way to mix and reproduce, so there is no way to prove whether such speculation is correct.

It seems that if you really want to unravel the secrets of the "ghost ancestors" of human beings, you will have to wait until the further development of science and the emergence of a large number of fossils about Homo erectus, and then all the mysteries can be solved. There are too many origins of human beings. The mysteries are waiting for us to discover and crack. The picture is from the Internet, and it must be deleted if it is infringed.
