The Dhaka Times Desk This time, 100,000 years ago teeth were discovered! Scientists have found an ancient tooth in a cave in Siberia.
These ancient teeth look very similar to human teeth. After examining this tooth, scientists said that it is the tooth of a hominin belonging to the family Homininae. Hominins are thought to have lived alongside humans in ancient times. This information was reported in a research report published in the journal Proceedings of the National Academy of Sciences. Earlier in 2008, a small finger bone was found in the same cave. Around 2010, a group of Russian scientists identified the finger bone as hominin.
According to media reports, scientists have named the animal as Denisova because the tooth was found in the cave named Denisova. After studying this tooth found, the researchers said, it was believed that the first men of these animals arrived at least 40 to 7 million years ago. But this idea seems to be wrong. Scientists say that they were roaming about 60 thousand years before this time. These animals, like Homo sapiens, were primitive men. They are very much like humans. They are very close to Denisovans or Neanderthals.
The tooth has been named Denisova 8. It is quite large for hominin teeth. The roots of these teeth are surprisingly long. It seems that the animal that has this tooth had a very large jaw.
Scientists say it is difficult to get a clear picture of an animal from a single tooth or finger. So it is not yet clear what this Denisovan actually looked like. Scientists believe that this tooth is 100,000 years ago. Scientists believe that they probably lived in Siberia.
Paleanthropologist Bence Viola of the University of Toronto is researching the tooth. According to the researchers, these animals had the strength to survive in a very harsh environment.
The DNA diversity of Neanderthals is similar to that of modern Europeans. According to Viola, Denisovan DNA is very close to Europeans. A National Geographic report suggests that Melanesians near Fiji or Papua New Guinea contain 5 percent Denisovan DNA.
However, to get a complete understanding of this animal, scientists believe that it is important to find fossils of this animal. And only then will more of the amazing history of this extinct animal come out.
