Neanderthals, Ancestors to Human Beings

Because of the lack of Homo sapiens' physique, they can not make full use of the intellect to compensate for it. The arrival of Homo sapiens from Africa brought the end of the Neanderthal people and extinction after 70,000 years. The first Neanderthal fossils were discovered in the mid-nineteenth century and proved to be highly controversial in the fields of anthropology, archeology and history. The Neanderthal fossils and studies are of concern to all humans. Because they provide a background in solving the mystery of human origin.

Modern humans, or Homo sapiens and Neanderthales, shared common ancestry about 500,000 years ago. Then they divided and evolved: the African man and the Eurasian Neanderthal. When humans ultimately entered Eurasia, they had sex with the Neanderthals and exchanged DNA. Today, about 2% of non-African DNA comes from Neanderthal's ancestors. Mr. Janet Kelso, bioinformatistan, who is studying the evolution of the genome at the Max Planck Institute in Germany, says:

In 2010, scientists completed the first sequence of the Neanderthal genome and found some genetic evidence that contemporary human ancestry at least occasionally crossed the Neanderthal people. Recent studies have shown that the DNA of Neanderthal people account for 1-4% of the modern Eurasian genome. According to the church, its benefits include an increase in genetic diversity. "One thing that is not good for society is low diversity," the church says. "If you become a single culture, you will face the great danger of extinction, so the recreational activities of the Neanderthales are primarily a matter of social risk aversion."

In 2010, researchers analyzed the DNA in fossils and revealed the existence of Denisovans. And it showed that the line has common ancestry with Neanderthals. However, the ancestors of the Denisovans and Neanderthal have divided from 410,000 to 470,000 years ago. Researchers revealed that the crown of the molar of the "baby" was almost completely worn. In order to help protect the fossils, researchers will use 3D X-rays from their teeth to help find the best way to extract as few powders as possible from tooth decay. Then they analyzed the small DNA they were able to survive from about 10 milligrams of toothpaste. And I confirmed that the fossil belongs to the girls of Denisovan.
