V. A. Yashnov in his work on crustaceans of Novaya Zemlya indicates that the current distribution of freshwater crayfish is best explained by the theory of drift: «With high probability we can say that in hydrobiology many issues of the distribution of lower aquatic organisms, at least Hemispheres can be solved on the basis of the principles of the theory of movement of continents.As an example, we mention the modern scattered distribution of Limnocalanus macrurus, for which passive movement (by wind and birds) due to lack of «at the stages of dormancy.
In the presence of a combination of both continents, according to Wegener’s theory, the distribution range of these species becomes relatively small.»
What could be the reason for the division of the continent?

The plot of the liberation of the rivers by Indra as a result of the murder of the Vritra that bound or barred them (Vrtra – harbor, abundance, mountain, from the root of Vrti – shell, cover, obstacle) seems to be extremely interesting for science. It is believed that in the Avesta, Vritra is attested as an independent mythological character of Varabragna. Indra gave the earth a firm footing and at the same time freed the fettered waters and fired the fire enclosed in the hill of Vritra.
In the ordinary sense, rituals dedicated to this feat of Indra could probably be perceived in connection with the spring opening of the rivers, the liberation of the waters from the ice and snow that bound them and with spring floods. But if you think about this plot, then at the mythological level such an interpretation is contradicted by the simultaneity and univariance of the phenomenon, repeatedly emphasized in the Rig Veda and Mahabharata, its clear localization, attachment to a specific geographical region, as well as some circumstances that characterize the incident as extraordinary event.
Considering the main characteristics of the battle of Indra and Vritra, we must note that the time and place of this incident are indicated exactly. According to the Mahabharata, it happened in Crete South.
«The tribes of formidable, ferocious, frantic tribes of Danavas, nicknamed the Kalei, lived in Crete South. In the Vritra…» The chronology of kings and sages – rishis testifies to the same. Thus, according to the Puranas and the Mahabharata, immediately after the assassination of Vritra, King Nahush took the place of Indra until he was overthrown and Yayati became his heir. The Yayati era lasted more than a thousand years, the time of the reign of Nakhusha also amounted to a significant period. Meanwhile, Yayati was considered «mainly belonging to Crete-yuga», that is, part of his era went beyond its borders (possibly in the «twilight» of Crete-yuga). Crete-yuga, according to the total length of 12,000 years adopted in the Mahabharata, began over 10,800 years and ended 6400 years before the last Kali-yuga began in 3102 BC, i.e. between 13900 BC and 9500 BC And if we take into account only Crete South itself without «twilight» (400 years each), then since 13500 BC until 9900 BC But the defeat of Vritra was to happen at least 1—1.5 thousand years before the end of Crete-yuga, i.e. between 13500 BC and 10500—10000 BC.
The location of the battle of Indra and Vritra is also quite localized.
Firstly, the action took place in the north, since after the destruction of Vritra Indra hid in the south in the cool «Sea of Manas», which, according to the Puranas, is located south of Kailasy (a lake region south of the Pinega River).
Secondly: after the crash of Vritra, Indra «released seven streams for running» and «Manu flowed up billowing water.» Here, one should probably recall that one of the highest peaks of the Polar Urals is called Manaraga and the Manaraga River flows from it. (It is interesting that, according to legend, the 13 forefather of Manu attached his ship to the spur of one of the highest peaks of Himavat during the flood).
Thirdly: Vritra was considered a daitya and a Brahmin, but on the whole the east side was Brahmin, and Vritra lay on the great river. The river, which was located in the northeast, is also mentioned in Avesta as the «good Daitiya» adjacent to Ardvi-Sura (Northern Dvina) in Aryan Wedja. This river of daityas could well be called the «waters of Manu» among the Aryans. The only great river flowing in the northeast from the Urals near the Northern Dvina is Pechora, the tributary of which is the Manaraga River.
