Hunter-gatherer culture change and continuity in the Middle Holocene of the Cis-Baikal, Siberia

Boreal forest hunter-gatherers who lived in the Lake Baikal region of Siberia between 9000 and 3000 years ago left behind a rich record of mortuary and habitation sites. In this article, we employ the results of human osteological, stable isotope, and faunal analyses to formulate an hypothesis about discontinuity in the development of Cis-Baikal hunter-gatherers. These data are further used to arrive at more specific working hypotheses on contrasting subsistence, mobility and social interaction patterns of the two cultures that inhabited the region at different times. We then provide a new model of culture change and continuity that features an intriguing 700- 800-year gap between these two groups' records of occupation within a context of practically no environmental change, (C) 2002 Science (USA).
