It will seem surprising, but in the Pleistocene epoch 40-12 thousand years ago, the appearance of Siberia was significantly
Instead of the usual taiga, the polar and subpolar regions of Eurasia were occupied by a vast tundra steppe. The biome’s climate was hot and dry, and the prairies stretched from southern Europe to the Far East.
A large number of sunny days in Siberia and lack of humidity were ideal conditions for animal breeding.
Such Siberia has become home to many animals — mammoths, woolly rhinos, bison, various predators and birds. It was once a truly prosperous and densely populated region. It is not surprising that ancient man felt comfortable here.
However, between 15 and 11 thousand years ago, the glaciers on the planet began to melt, and the climate in Siberia became humid. Now the grass was rotting, and their place was taken first by shrubs, and then by conifers.
Changes in plant composition provoked the extinction of large animals. Further climate change made Siberia look like modern Siberia. Together with the animals, a huge number of ancient people died out, who migrated here 45 thousand years ago.
The remaining communities were able to adapt to the environment and became the ancestors of the Siberian peoples. However, they spent all their resources on survival; the development of society and technology was out of the question. The normal development of Siberia began by the Russians only in the 17th century.
