DNA extracted from the skull and molar of early human remains in the southern Caucasus region of Georgia provides evidence of a new ancestry for modern Europeans. According to Reuters, scientists announced that they examined the genomes of two individuals, one who lived 13,300 years ago and another 9,700 years ago, concluding that they belonged to an unknown lineage that is genetically related to modern Europeans. These individuals were part of groups that settled in the Caucasus—where Georgia meets southern Russia—around 45,000 years ago, living by hunting animals and consuming plants. They had migrated from Africa to these regions. At that time, Neanderthals (another species of early humans) inhabited Europe. According to scientists, these individuals remained isolated and without contact with other humans for a thousand years during the Ice Age. The melting of ice at the end of the Ice Age brought them back into contact with other humans, leading to the spread of horseback riding, herding, and metallurgy in Western Europe about 5,000 years ago. Daniel Bradley, a geneticist at Trinity College Dublin, stated, 'Modern Europeans are a mix of ancient ancestral species. The only way to decipher them is to trace their genomes from thousands of years ago when gene mixing had not yet occurred.' Before this discovery, scientists had identified three lineages of Europeans. Andre Manica, a geneticist at the University of Cambridge, noted that 'the inhabitants of the Caucasus represent a fourth lineage that was previously unknown.' They played a significant role not only in the ancestry of Europeans but also in Central Asia and the Indian subcontinent. Bradley described this finding as 'an important new piece in the puzzle of human ancestry.' According to Ron Pinhasi, an archaeologist at University College Dublin, the inhabitants of the Caucasus lived in groups of 20 to 30 in caves. One of the two sets of remains was discovered in a cave near the village of Usakhelo in western Georgia, and the other was found 40 kilometers away in another cave near the village of Kumistavi. This research has been published in the journal 'Nature Communications.'
Discovery of a New European Ancestry in the Caucasus
Scientists have discovered a new lineage of early humans in the Caucasus region of Georgia, which is genetically linked to modern Europeans. This finding sheds light on the ancestry of Europeans and their migration patterns from Africa. It is significant as it adds a previously unknown lineage to the understanding of human evolution.
