Finding the teeth of a child of an extinct species of humans
In the forests of Laos in China, a child's molar was found, and this molar belongs to a species of humans that we do not know much about. Researchers conducted a new study that shows from analyzes of the internal structure of the tooth that it may belong to a girl of the genus Homo.
When the molar was found, it was found that it represented an extinct species of humans. It was first discovered when the finger bone of a child found in a cave in Siberia in 2008 AD was analyzed, and it did not correspond to any known human type at that time.
Since the molar did not complete its growth and development until close to the time of the person’s death, the scientists concluded from this that the corpse is the body of a child, and the researchers believe that this child is between three to eight years old at the time of death, and by studying and analyzing the proteins present for this molar, the scientists were able Determine the sex of the body that it is female.
Using the sediments that were present around this molar, it dates back to more than 130,000 years, and the research team made sure by analyzing the proteins in the molar, in addition to its shape, that it belongs to a Denisovans.
Denisovans
?! What is a Denisovans
Denisovans lived in a wide range of environments, and were able to adapt to harsh conditions from the cold mountains of Altai (Russia) and Tibet to the tropical forests of Southeast Asia.
Denisovans are considered one of the extinct species of humans of the genus Homo that lived on Earth thousands of years ago. In March 2010, scientists announced the discovery of a part of a female toe bone that lived about 41,000 years ago. It was found in the Denisova Cave near the Altai Mountains in Siberia. DNA analysis that this species is genetically distinct from primitive and modern humans.
The “Denisovans” man was named by this name in relation to the “Denisova” cave near the Altai Mountains in Siberia, which was inhabited by neanderthals and modern times. This cave was named after a hermit called “Denis” who lived there in the eighteenth century.
Denisovan is one of the extinct species of humans and was initially believed to be of the genus "Homo", but the analysis of its DNA proved that it does not belong to any other species we know from the members of the genus Homo, so it was named after the cave in which it was found.
Denisovans existed 400,000 years ago and became extinct 40,000 years ago.
According to scientists, Denisovans are more widespread than Neanderthals, who also shared the world with Homo sapiens. Their genes still live in some of us until today. It is clear that modern humans are the product of a mixture of species that evolved separately and then intermarried.
Geneticists believe that the group of Denisovans was actually a sister group to Neanderthals, and studies indicate that their common ancestor branched off from our lineage about 600,000 years ago, and then Denisovans separated from Neanderthals about 200,000 years later.
After studies and analyzes of the genome, it was found that the “Denisovans” group was in fact a sister group to the “Neanderthals”, and they may have separated in the Middle East, so the “Neanderthals” went to Europe and the “Denisovs” went to Asia, and given the recentness of the Denisova Cave sample, it is reasonable Being a Denisovan.
Denisovans existed about 400,000 years ago, while modern humans only appeared 200,000 years ago, and through studies, genetics sees that the Denisovans interbred with primitive modern humans somewhere in what is now called Southeast Asia, where they separated from a human being. Neanderthals “apparently in the Middle East and spread in the north towards Siberia, and in the east towards Indonesia, and on his way he had to cross one of the largest natural barriers on earth, the “Wallace Line” which extends across the Lombok Strait, the deep marine channel separating the two Indonesian islands, Bali and Lombok. .
Scientists do not know when the Denisovans became extinct, but about 400,000 years of evolution, as well as intermarriage with humans may have changed his physical appearance, and it turned out that he intermarried with a Neanderthal man as well.
As for the new discovery, it was found in 2012 AD in a large group of bones discovered from the same cave, and after analysis and searching for its DNA sequence, it was confirmed that it was part of the bones of a 13-year-old teenage girl, who lived 90,000 years ago in the area Around Denisova Cave, located in the Altai Mountains of Siberia, this cave is a treasure for specialists in the study of the history of human ancestors, as it was inhabited by multiple races of humans, including modern humans, or Homo sapiens, which we all know as "Homo Sapiens".
“Homo” simply means “the human race,” and the word “Homo” basically means “human” in Latin. Only the modern human species remains of this genus. As for the rest of this genus, it has become extinct for reasons that we are trying to study until now.
The age of this genus is estimated at about 2 million years with the beginning of the emergence of what we call the skilled human being. The genus Homo was distinguished by several characteristics. For example, the size of its skull was large, and thus it included a large space for the brain. Also, this genus was able to walk on two of its limbs, and those were the most important His qualities, he was also able to build complex tools, and he was able to communicate in a way that clearly evolved to reach modern humans, while both Neanderthals and Denisovans are our closest relatives.
