Scientists Found New Ethnic Group That Resided in Siberia During Ice Age from DNA of Milk Teeth

Scientists have found thousands of years old milk teeth underground a remote archaeological site in northeastern Siberia. The DNA extracted from thirty-one-thousand-year-old human teeth has resulted in the fining of a new cultural group. It is a new Ice Age community including hunters that survived deep inside Siberia. As per scientists, the group existed in the extreme conditions in Siberia. A new study reveals, those ancestors hunted woolly animals like mammoths, bison and rhinoceroses. While scientists call them the Ancient North Siberians and portray their survival as a crucial part of the human story.

Professor Eske Willerslev from St John’s College, University of Cambridge is the leading scientist of the study. He also led the international team of scientists involved in the study. The team of scientists found two milk teeth near Russia’s Yana River. Scientists found the archeological site, Yana Rhinoceros Horn Site (RHS), in 2001, it is also a treasure of artefacts and other tools of human residence. Thus the study, published as a part of a broader study in Nature, reveals the Ancient North Siberians expanded at the same time as the ancestors of modern-day Asians and Europeans. Scientists surmise those human ancestors occupied large areas of the northern hemisphere.

Besides, scientists assert these people have close ties with those who later became the first Native of Americans. Study’s first author Dr Martin Sikora, from Denmark University, said these discoveries had transformed the knowledge about human history. As per the research team, at the time, around 40-500 people lived there. After performing DNA analysis of the milk teeth, scientists have not found any proof of intermarriages which took place in the falling Neanderthal community at that time. According to Prof Willerslev, the remains are quite similar to the ancestors of Paleo-Siberian speakers. Thus it is an essential finding revealing the mystery of human evolution in the region. He added it is the first time they have discovered such close genetic connections outside the U.S.
