Prehistory of Siberia Siberia were hunter-gatherers, whose prey consisted of mammoths and reindeer, and occasionally fish as well. In the 6th millennium BC, pottery spread across the whole of Siberia, which scholars treat as the beginning of the Siberian neolithic. Unlike Europe and the Near East, this event did not mark a major change in lifestyle, economy or culture. The prehistoric inhabitants of the vast areas of taiga and tundra east of the Yenissei and north of Baikal differ in many ways from the prehistoric cultures of the other parts of north Asia. There is stronger evidence than usual for settlement continuity here
Russian conquest of Siberia eastern borders of Russia had expanded more than several million square kilometres. In a sense, the khanate lived on in the subsidiary title "Tsar of Siberia" which became part of the full imperial style of the Russian Autocrats. The conquest of Siberia also resulted in the spread of diseases. Historian John F. Richards wrote: "... it is doubtful that the total early modern Siberian population exceeded 300,000 persons. ... New diseases weakened and demoralized the indigenous peoples of Siberia. The worst of these was smallpox "because of its swift spread, the high death rates, and the permanent disfigurement of survivors."
