The materials of investigations of the early Neolithic campsite Orechovo-Donetskoe 3 in the basin of the Seversky Donets are published in this paper for the first time. The authors argue, that this site belongs to a number of numerous other sites of the hunters, collectors and fishers of so called Bondaricha stage who have extended in 6 thousand calBC in the territory of a left bank of the Seversky Donets and partly, in the Dnieper rapids area. They analyse the reasons of considerable demographic transformations at a boundary between Mesolithic and Neolithic in this region, regard the ways of communications and contacts of the population of Donets culture, show the importance of social changes as a prerequisite of process of Neolithisation.
