Neolithic and early Bronze Age of Cis-Baikal: chronology and dietary trends

Analyses of radiocarbon dates (all corrected for the freshwater reservoir effect) and associated stable isotope values obtained from the skeletal remains of ~560 individuals provide many new insights about Middle Holocene hunter-gatherers (HG) of the Cis-Baikal region, Eastern Siberia. The new radiocarbon evidence clarifies the culture history of the region by defining better the boundaries between the chronological (archaeological periods) and cultural (mortuary traditions) units, as well as our understanding of the transitions between them. Furthermore, differences between the four archaeological micro-regions with regard to the timing and duration of these culture historical units have come into focus for the first time. In terms of dietary patterns, the Early Neolithic foragers of the Angara and Southwest Baikal trended towards a greater reliance on aquatic foods. A similar trend was found in the Late Neolithic Isakovo group on the Angara, while the Late Neolithic Serovo group in the Little Sea trended towards an increased dietary reliance on terrestrial game. In the Early Bronze Age HG, a mosaic of dietary patterns was found: some groups experienced dietary shifts (frequently emphasizing different foods), while other groups displayed stability. Such differences were found even between close neighbours. All these results suggest significant variation in patterns of culture change within and between archaeological periods, mortuary traditions, and micro-regions. Some cultural patterns developed at a quick pace, others much more slowly; some appear to have collapsed rapidly, while others probably went through a more gradual transition to a different pattern. Additionally, this large set of radiocarbon dates allows novel insights into patterns of cemetery use: some seem to have been used continuously, others only sporadically, and some show long periods of disuse. Moreover, some cemeteries of the same mortuary tradition were apparently in use substantially earlier than others were even established. In sum, Cis-Baikal Middle Holocene HG strategies underwent a range of changes not only at the boundaries between relevant culture historical units but also within such units. New insights suggest considerable spatio-temporal variation in the nature, pace, and timing of these developments

Неолит и ранний бронзовый век Предбайкалья: пространственно-временные паттерны использования могильников [Neolithic and Early Bronze Age of Cis-Baikal: spatiotemporal patterns of cemetery use]

Hunter-gatherer archaeology typically focusses on the details of subsistence strategies and material culture and, in the case of cemeteries, on various aspects of mortuary practices, beliefs, and social differentiation. This paper aims to look rather at patterns of change over time and space in how past hunter-gatherer cemeteries were used from Late Mesolithic to Early Bronze Age (~8600–3500 cal BP) in the Cis-Baikal region of Eastern Siberia. The approach is based on a Kernel Density Estimate methodology applied to 560 radiocarbon dates obtained for individual burials from 65 cemeteries and representing 5 distinct mortuary traditions. This enables a number of different types of analysis to be performed at different scales: (1) It is possible to examine the overall tempo of burial events at each cemetery or a group of cemeteries; (2) Within each cemetery the spatial patterns of the sequence of graves and burials can be analyzed further; (3) It is possible to compare the different cemetery-specific chronologies within the microregional or regional context; and (4) Although tentatively at this time, the spatiotemporal pattern of cemetery use over the whole region can be visualised. The spatiotemporal analysis of individual cemeteries shows that each one had its own pattern, some very distinct and clear in their characteristics, which relate to the role the cemetery played for the local group, and within the microregional or regional population. On the regional scale some broader patterns such as shifts in frequency of burial events between microregions within mortuary traditions are visible. However, at this scale the existing sampling biases require caution in assessment of the results and future fieldwork will help improve the analysis and insights. On the other hand, many of the individual cemeteries have been excavated in full and such comprehensive datasets already provide a range of entirely new and important insights into cemetery use by the Middle Holocene hunter-gatherers of Cis-Baikal

The first horse herders and the impact of early Bronze Age steppe expansions into Asia.

The Yamnaya expansions from the western steppe into Europe and Asia during the Early Bronze Age (~3000 BCE) are believed to have brought with them Indo-European languages and possibly horse husbandry.

Middle Holocene hunter–gatherers of Cis-Baikal, Eastern Siberia: chronology and dietary trends

Analyses of radiocarbon dates (all corrected for the freshwater reservoir effect) and associated stable isotope values obtained from the skeletal remains of ~650 individuals provide many new insights about Middle Holocene hunter–gatherers (HGs) of the Cis-Baikal region, Eastern Siberia. The new radiocarbon evidence clarifies the culture history of the region by defining better the boundaries between the chronological (archaeological periods) and cultural (mortuary traditions) units, as well as our understanding of the transitions between them.

In terms of dietary patterns, the Early Neolithic foragers of the Angara and Southwest Baikal trended towards a greater reliance on aquatic foods. A similar trend was found in the Late Neolithic (LN) Isakovo group on the Angara, while the LN Serovo group in the Little Sea trended towards an increased dietary reliance on terrestrial game. In the Early Bronze Age HGs, a mosaic of dietary patterns was found: some groups experienced dietary shifts (frequently emphasizing different foods), while other groups displayed stability. Such differences were found even between close neighbours.

Spatio-temporal patterns of cemetery use among Middle Holocene hunter-gatherers of Cis-Baikal, Eastern Siberia

Chronology of middle Holocene hunter-gatherers in the Cis-Baikal region of Siberia: Corrections based on examination of the freshwater reservoir effect

A dataset of 256 AMS radiocarbon dates on human skeletal remains from middle Holocene cemeteries in the Cis-Baikal region, Siberia, and associated carbon and nitrogen stable isotope values are analyzed for new insights about culture history and processes of culture change. First, based on the typological criteria all dated human burials are assigned to mortuary traditions and typochronological units-Late Mesolithic, Early Neolithic, Late Neolithic and Early Bronze Age. Next, all dates are corrected for the Freshwater Reservoir Effect (FRE) according to the regression equations developed using paired radiocarbon dates on human and terrestrial faunal remains from the same graves and examined for chronological trends using a Bayesian approach. While the entire corrected culture historical sequence is younger by roughly 200-400 years relative to the previous model the shift of the specific period boundaries is not systematic due to the varying proportion of aquatic food in the diets of the relevant groups. Examination of the dataset subdivided into smaller spatio-temporal units provides additional insights. During the Early Neolithic, in the Angara and Southwest Baikal micro-regions there is a chronological trend toward increased reliance on aquatic food. During the Early Bronze Age in the Little Sea micro-region, there appears to be a trend toward increased reliance on the Baikal seal. This shift, however, can also be interpreted as increasing migration over time of new groups from the Upper Lena. The sample from the Early Neolithic Shamanka II cemetery in Southwest Baikal shows two non-abutting phases of use each displaying a trend toward greater consumption of aquatic foods. These findings provide new chronological framework for the study of other cultural changes affecting middle Holocene hunter-gatherers in the region. The results may also allow better correlation with other sequences, cultural and environmental, that are not affected by the FRE
