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.

Geological research has convincingly shown that during the existence of Australopithecus the Earth’s climate became more dry, rain forests receded. Australopithecus lay in wait for the danger in open, treeless spaces. They needed to obtain food, including hunting. The lack of strong claws, teeth, adequate muscular strength has led to unique achievements, namely: the use of stone, sticks as tools and protection tools.
All in some way affected their evolution. As shown by the finds of parts of the skeletons of the Australopithecines are similar to man in structure of the several parts of the body. They moved on two legs. Over time they have adapted to changing environmental conditions.
So, the anthropoids, and fossil apes, in groups-herds, used the first tools: rocks, sticks for defense and obtaining food. But what food?
The materials of archaeological, geological and paleontological research in recent decades has shown that the Australopithecines used not only vegetable foods but also animals.
Hunting occupied a large place in the economy of the ancient people — it is an indisputable fact, but the premise of development as a form of practice originated and formed another prehuman stage of anthropogenesis. Predposlednyaya (omnivorous) originated from arboreal monkeys in the moment of transition, when they began to eat new kinds of plants growing on the ground, small animals, insects, perhaps, and the corpses of large animals and then to hunt with the stones that were originally used only in self-defense. Therefore, bone remains of animals, such as baboons, found along with the bones of Australopithecus, which bore traces of blows with blunt objects, they force you to change perspective on the nature of economic activities of the ancient hominid as a purely collecting economy. The predominance in the diet of human ancestors eating meat is a positive impact on the formation of the brain of higher fossil apes that had already been noted by F. Engels. Continue reading
The Museum “Archaeology, Ethnography and ecology of Siberia” of the Kemerovo state University begins its story since the 70’s, when Professor A. I. Martynov (head of. the Department of archaeology) and Professor T. N. Vagina (head the Department of Zoology) began to create the Metropolitan museums of archaeology and Zoology. Their work was crowned with success. In 1980, the museums were open. Presented in the Museum materials were collected by teachers and students of historical and biological faculties more than 30 years.
In 1997 the museums combined. Today the Museum is a major unit of the University, which has a library, a Photograph collection, an archive . restoration and taxidermy workshops, laboratory, office, storage, classrooms.
The Museum has more than 310 000 units. In addition to materials on archeology and Ethnography of southern Siberia, there are copies of petroglyphs of the Altai, Khakassia, Tuva, Kazakhstan and Kyrgyzstan, osteological. paleontological, Zoological, entomological and ornithological collections.
With the collections of our Museum are schoolchildren. students, graduate students. scientists and leading specialists from different countries. The Museum funds and expositions are a training base for specialized courses and practical classes on the history of primitive society, Ethnography, museology and ecology I.
The Museum created a Board of leading specialists of the relevant branches of science under the leadership of Vice-rector of University Ph. D. Professor B. P. Nevzorova. The Museum holds archaeological, Museum practices, Museum staff are actively involved in the creation of scientific works, scientific-methodical recommendations. Actively implemented the program “Museum – school – the unified educational space” for use of the regional component of school curricula for history, geography, biology and ecology. In the halls of the Museum are the feasts of the presentation of scientific papers, exhibitions, conferences. Continue reading
