The new theory of vortex (ring) determinism, which focuses on the existence of internal causal sources, could not ignore the problem of the evolution of species of living organisms. According to Darwin's concept, the credit for the development of species belongs entirely to external conditions and random mutations of genes. This concept should be recognized as a product of philosophical objectivism in its purest form. And vortex determinism radically corrects the situation, simultaneously raising the banner of Lamarckism on the shield.

n one natural area, animals may have different distribution. In some areas they inhabit, and in other areas, they do not inhabit. Scientists have been working on this issue for a long time. In this study reports that the species composition and distribution of species varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia. The largest number of species in the region belongs to those living in coniferous and broad-leaved forests (42.9%). In the second place in terms of representation are species widely distributed in several natural areas (28.5%). They are slightly inferior to the types of steppe fauna (25%). The taiga type of fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.
