| Mathematical linguistics, geography, archaeology, mythology, onomastics, ethnography are consolidated for the study of prehistoric ethnogenetic processes in one project under the common name Alternative Linguistics. The main instrument of the research is a special graphic-alalytical method developed by the author and described 1987 in a Russian academical magazine. The essence of this method consists in the construction of the graphical models (diagrams of the mutual relation of monophyletic languages. These models are constructed on the postulate of the reverse-proportional dependence between the quantity of common words in the pairs of cognate languages and the distance between the areas of forming these languages out of the original unitary language. Suitable places for each such model were been determined on the geographic map of Eurasia. |
