How the Slavs conquered Russia

05.05.2006
Geneticist specialists from the Institute of Biological Problems of the North, Far-East Branch of Russian Academy of Sciences, are reconstructing the picture of Eurasia colonization by the Slavs. According to the researchers’ opinion, the Slavonic men and women jointly developed the territory of the south of contemporary Russia. However, after the 9th century, women used to stay at home, and colonization of the east and north was mainly performed by men.

This conclusion was made by geneticists through analyzing variable consecutions of DNA of mitochondria and of some sections of Y-chromosome with representatives of 10 Russian populations from the Stavropol Territory in the south through the Pskov Region in the north and from the Orel Region in the west through the Nizhni Novgorod Region in the east. The mitochondrial DNA is inherited from generation to generation along a female line, DNA of Y- chromosome – along a male line. Analysis of variability of these consecutions allows to judge about migrations of our forefathers and foremothers.

Along the maternal line, Russian populations are rather close to each other. They can be conditionally split into two zones. Inhabitants of the south-eastern zone (including the Orel, Rostov, Kursk, Kaluga and Saratov Regions and the Stavropol Territory) have the roots among western Slavs, Baltic and some Finno-Ugric nations (Poles, Lithuanians and Estonians). Ancestors of Russians in the north-eastern zone took wives from the Finno-Ugric and other nations of Eastern Europe (Finns, Karelians, Maris, Tatars and Adygeis).

Comparison of Y-chromosomes of Russian populations provides different results. Only the Pskov and coast-dweller populations are close along the paternal line to the Finno-Ugric and Baltic nations of the Northern and Eastern Europe, the overwhelming majority of Russians are relatives to the Poles, Ukrainians and Byelorussians. Judging by consecution variations of the “male” chromosome, the Slavs, arriving in various locations of Eastern Europe, contacted in different ways with residential population: in some places - closely and in some others – otherwise.

Genetic analysis results agree with the anthropological data, according to which Russian populations can be divided into three zones. In the western part of the ethnic territory, Russians descend from the Slavs who had come from Central Europe. Russian population of the central part appeared as a result of mixture of the Slavs with the Finno-Ugric nations, Eastern European mothers dominating in these populations, and the population of the North evidently has in its genealogy Finno-Ugric ancestors of both sexes. According to the geneticists, the reasons for these differences are caused by different participation of men and women in Slavonic migrations. Women apparently participated only in early phases of the Slavs’ migration into Eastern Europe. Starting from the 9th century, colonization of the east and the north of Eastern Europe was mainly performed by men who chose wives from residential population. The obtained picture needs more precise definition, therefore the researchers are planning to further investigate variability of specific “maternal” and “ paternal” DNAs in different Russian populations.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
