A new genetic analysis of archaeological finds has shown that some of the early inhabitants of Europe mysteriously disappeared by the end of the last ice age, and were largely replaced by other.
The discovery was confirmed by the analysis of dozens of ancient fossils, collected throughout Europe. Genetic replacement is likely to be the result of rapid climate change, which earlier inhabitants of Europe are unable to adapt quickly enough, says study co-author, Cosimo Post, archaeogenetic doctoral student at the University of tübingen in Germany.
The temperature change at the time was “huge compared to climate change in this century” . — told the Post. “Imagine that the environment has changed quite dramatically”.
Twisted family tree
Europe has a long and complicated genetic heritage. Genetic studies have shown that the first modern humans who came from Africa, somewhere between 40 and 70 thousand years ago, soon began to mate with local Neanderthals. At the beginning of the agricultural revolution, 10-12 thousand years ago, farmers from the Middle East walked across Europe, gradually displacing the local hunter-gatherers. thousand years ago, nomadic horsemen called Yamna came from the steppes of the present Ukraine and mingled with the local population. In addition, according to the survey for 2013, published in the journal Nature Communications . found another lost group of ancient Europeans mysteriously vanished about 4.5 thousand years ago.

If someone is lucky enough on the beach to find fossilized seashells, it is possible to recognize them easily. But there are many fossils, looking for that hard to guess what they represented. The problem is compounded by the fact that many of the fossils are incomplete or poorly preserved. Sometimes the doubts are even scientists. In our review of the 10-ka fossils, which for many decades was not recognized.
Fossilized Ammonites are quite common today, but for thousands of years it took for anything except shellfish. The ancient Greeks thought they were RAM horns, and named the Amish in honor of the Egyptian God Amun, who was depicted with similar horns. The ancient Chinese called it the stone-horns for the same reason. In Nepal, fossilized Ammonites were considered a relic left by the God Vishnu. The Vikings thought of them as sacred petrified offspring of the world serpent of Ermengarda.
In the middle ages Ammonites were known in Europe as snake stones because it was believed that it was the petrified body of a coiled serpent, which turned into stone and Christian saints. Today it became known that the Ammonites is only fossilized shells of creatures that became extinct about four hundred million years ago. Continue reading
In Hunan province (southern China ) found the remains of ancient people who moved here from Africa 120 thousand years ago. It is the most ancient human remains in Eurasia. The article with the new study appeared in the journal Nature .
Previously it was believed that the first people in China were 80-100 thousand years ago, however, the findings in the cave of Fuyang, located in Hunan province, have changed scientists ‘ ideas.
In a cave a few dozen teeth and other remains, after analyzing which a group of anthropologists were surprised to find that before them the remains of the oldest Homo sapiens in Eurasia – they range in age from 80 to 120 thousand years. Thus Hunan and southern China is including the place for the first emergence and the further resettlement of Chinese on Chinese territory.
New evidence suggests that mankind has left the bounds of its “cradle” much earlier than we previously thought, approximately 40-70 thousand years more than previous estimates.
New discoveries of scientists also poses another question – why in China our ancestors appeared earlier than in Europe? Put forward the hypothesis that in Europe and the middle East prevented the CRO-magnons Neanderthals and the cold climate to which the CRO-magnons, came from Africa, were not adapted.
The Chinese and the Indians – one blood Continue reading
