Gamkrelidze, Tamaz V.; Vjacheslav V. Ivanov. “Indo-European and the Indo-Europeans” (1995, Mouton de Gruyter. ISBN 3-11-014728-9.). This two distinguished academisian, sientiests approved (comparative linguistics) that Proto-Indo-European language minimum was spoken during the 4th millennium BC in the Armenian Highland. And for reconstructing the Proto Indo-European Language is possible only through Armenian and Old German languages.

Colin Renfrew, “Archeology and Language: the Puzzle of Indo-European Origin” (Renfrew, A.C., 1987, London: Pimlico. ISBN 0-7126-6612-5). Andrew Colin Renfrew, Baron Renfrew of Kaimsthorn is an English archaeologist, noted for his work on the radiocarbon revolution, the prehistory of languages, archaeogenetics, and the prevention of looting at archaeological sites. In 1980 Renfrew was elected a Fellow of the British Academy. In 1987, he published Archaeology and Language: The Puzzle of the Indo-European Origins, a paper on the Proto-Indo-Europeans. His work posited that this group lived 2,000 years before the Kurgans (7-8 millennium BC), in the teritory of the East part of Modern Turky (Armenian Highland, Historical Armenia), later diffusing to Greece, then Italy, Sicily, Corsica, the Mediterranean coast of France, Spain, and Portugal. Another branch migrated along the fertile river valleys of the Danube and Rhine into Central and North Europe.

Luigi Luca Cavalli-Sforza. He is one of the more distinguished geneticists of the 20th century, he has summed up his work for laymen under five topics covered in “Genes, Peoples, and Languages (2000). Physiologist and evolutionary biologist Jared Diamond praised the work for “demolishing scientists’ attempts to classify human populations into races in the same way that they classify birds and other species into races (The Human Genome Survey, 1 July 2000, pg. 11)

Cavalli-Sforza’s The History and Geography of Human Genes (1994, with Paolo Menozzi and Alberto Piazza) is a standard reference on human genetic variation. Cavalli-Sforza also wrote The Great Human Diasporas: The History of Diversity and Evolution.

Once the genetic structure of inheritance had been made plain, Cavalli-Sforza was one of the first scientists to ask whether the genes of modern populations might contain an inherited historical record of the human species. The study of demographics was already well-established, based on linguistic, cultural, and archaeological clues. Cavalli-Sforza initiated a new field of research by combining the concrete findings of demography with a newly-available analysis of blood groups in an actual human population. Cavalli-Sforza has studied the connections between migration patterns and blood groups.

Cavalli-Sforza and Anthony Edwards were always concerned with trees of populations within the human species, where genetic differences are affected both by treelike patterns of historical separation of populations and by spread of genes among populations by migration and admixture. Cavalli-Sforza has been concerned with the effects of both divergence and migration on human gene frequencies.

Renfrew-Dolgopolsky-Cavalli-Sforza model provides a homeland (Armenian Highland and Anatolia) and general rate of expansion that can be traced in the archaeological record.

Renfrew used radiocarbon archaeology, Dolgopolsky used the comparative lingustic method, Cavalli-Sforza used the genetic comparative method. All of the scholars reached the same conclusion.

In the book of Merritt Ruhlen, an American linguist, provides Renfrew-Dolgopolsky-Cavalli-Sforza model wich approves that the very homland of Caucasoid race: the first farmers, who spoke the Proto Indo-European (Aryan) language, originated in the Armenian Highland and Anatolia (“The Origin of Language: Tracing the Evolution of the Mother Tongue” (1994, Toronto, pp. 186-188).

¦Languages, like genes, provide vital clues about human history. Here we analyse linguistic data using computational methods derived from evolutionary biology. Indo-European languages expanded with the spread of agriculture from Anatolia around 8,000–9,500 years BP(before present time). In striking agreement with the Anatolian hypothesis, our analysis of a matrix of 87 languages with 2,449 lexical items produced an estimated age range for the initial Indo-European divergence of between 7,800 and 9,800 years BP. These results were robust to changes in coding procedures, calibration points, rooting of the trees and priors in the bayesian analysis. Figure 1 shows that the Greco-Armenian lineages are shown as distinct more than 7,000 years BP. ²ÛëÇÝùÝ, ѳۻñ»Ý É»½áõÝ ³ñ¹»Ý ³éÝí³½Ý 7000 ï³ñÇ ³é³ç áñå»ë ÇÝùÝáõñáõÛÝ É»½áõ ³é³ÝÓݳó»É ¿ ݳ˳Ñݹ»õñáå³Ï³Ý Ù³Ûñ É»½íÇó Çñ ÇëÏ Ñ³Ûñ»ÝÇùª гÛÏ³Ï³Ý É»éݳß˳ñÑáõÙ£
