It was not until 1829 that scientists discovered an ancient human skull fossil different from modern people in Belgium, and in 1859, skulls and other skeleton fossils were found in a cave in the Neanderthal valley in Germany. So scientists named this ancient human Neanderthal after Neanderthal Valley. Since then, traces of Neanderthal life have been found all over Europe, from Uzbekistan in Central Asia to Palestine in the East.
Based on these findings, scientists speculate that Neanderthals appeared at least 230,000 years ago, and they have existed in the same time and space as their ancestors for a long time. The most brilliant period, widely distributed in the western part of Eurasia. However, how Neanderthals became extinct is still inconclusive. There are two kinds of specific guesses.
The first guess is that Nigerians became extinct because of environmental changes. This speculation holds that the extinction of Nepalese people is the same as the extinction of dinosaurs. Because the last ice age on earth happened more than 30 thousand years ago, the whole of Europe was shrouded in cold. The cold weather led to poor land and fewer animals, and the living environment of Neanderthals deteriorated day by day. They had to run like hell to find some food.
At this time, Neanderthals obviously could not adapt to this change in foraging environment, and with the spread of glaciers throughout Europe, Neanderthals eventually went extinct. This theory of environmental change is tantamount to clarifying that the ancestors of modern people were the "culprits" of the extinction of Neanderthals. For a long time, many scientists believed that the extinction of Neanderthals was caused by the ancestors of modern people.
The second guess is that Homo sapiens is extinct. Neanderthals died out about 30,000 years ago, when Homo sapiens entered Europe. Therefore, some scientists believe that Nigerians have been at a disadvantage in the competition with Homo sapiens for a long time, gradually being driven away and killed, hiding in Gibraltar, a corner of western Europe, and finally being completely extinct. Many scientists hold this view, including American geneticist George Mcdonaldchurch.
Church, a geneticist at Harvard University, studied Neanderthals for a long time. He believes that the ancestors of modern people are the "culprit" of the extinction of Neanderthals, not the cause of environmental change. Although this kind of killing was normal in the ancient competition for survival, Church always believed that Homo sapiens was responsible for the extinction of Nigerians. Moreover, he thought that Neanderthals had large brains and were certainly smarter than Homo sapiens, and their way of thinking could also benefit mankind. So he came up with a bold idea, that is, using modern technology to revive Neanderthals. This technology is cloning.
The man claimed that the technology of resurrecting Neanderthals was mature and he had the ability to do it. He has extracted enough DNA from Neanderthal bone fossils to reconstruct Neanderthal population DNA. Now the reading speed of DNA technology is one million times faster than before, and man has successfully cloned many animals, so he thinks he has the ability to revive this ancient man. Church claimed that the biggest problem he faced was not technology, but mature technical conditions. The biggest problem is to find an adventurous female volunteer, specifically, to find a surrogate mother. As long as he can find it, he is confident that Neanderthals who have been extinct for 30 thousand years will return to this world. But this adventurous man, he has never found it, and it is impossible to find it.
The main reason is also very simple. Church's behavior is simply an anti-evolutionary behavior, which belongs to the behavior that violates the laws of nature. If he really succeeds, many questions will follow, such as what exactly are Neanderthals? According to the skeleton fossils of Neanderthals, Neanderthals did have bigger brains than early modern humans, but just because they had bigger brains doesn't mean they were smarter.
In addition, Neanderthals are similar to modern European whites in skin color, and their physical appearance is also different from modern people. Their average height is 1.5 to 1.6 meters, and they are ugly. Their foreheads are flat, their mandibles are large, and their front teeth are shovel-shaped. Many Neanderthals had bad teeth, and the only thing that was stronger than modern people was their stronger limbs. And Nigerians have been extinct for 30,000 years. Even if it is resurrected, it is difficult to adapt to the current environment and survive. They can only be reduced to samples of human research, which not only violates the laws of nature, but also does not conform to morality and ethics. So Church's idea is doomed to be unsuccessful.
