This overview is based on the results of 25+ years of provenance studies to identify the sources of high-quality volcanic glass (obsidian) in prehistoric cultural complexes of the far eastern and northeastern regions of Russia (Maritime Province, the Amur River basin, Sakhalin Island, the Kurile Islands, Kamchatka Peninsula, Chukotka region, the Kolyma River basin, and the High Arctic), as well as in adjacent parts of Northeast Asia (Hokkaido Island, the Korean Peninsula, and Manchuria). The extended networks of obsidian exchange in antiquity are reconstructed for the southern Russian Far East and Northeastern Siberia. A possible mechanism of long-distance obsidian exchange/trade in Northeastern Siberia is suggested.

The current situation with studies of prehistoric plant cultivation in the Russian Far East is presented. A critical analysis of existing concepts and models of the oldest agriculture in this region is also included. Reliable data allows us to conclude that humans in the southern Russian Far East (Primorye Province) began to cultivate millet at c. 4700–4600 BP (c. 3600–3400 calBC) in the context of the early Zaisanovka cultural complex of the Late Neolithic. The most probable source area for prehistoric agriculture in the Russian Far East was neighbouring Northeast China (Manchuria).

The discovery of Neolithic (i.e. pottery-containing) components at the Ust-Karenga 12 site in northern Transbaikal brought to light new data on the appearance of pottery in Siberia. Excavations and geoarchaeological studies identified the pottery complex in layer 7, 14C-dated to c. 12 180–10 750 BP (charcoal dates) and c. 11 070–10 600 BP (pottery organics dates). The pottery is thin and plant fibre-tempered; vessels are round-bottomed and with a comb-pattern design. Ust-Karenga 12 thus preserves by far the earliest Neolithic assemblage in Siberia, and is only slightly younger than the Initial Neolithic complexes of the Amur River basin, Russian Far East (c. 13 300–12 400 BP).

The earliest pottery from the Russian Far East, Osipovka and Gromatukha cultural complexes, was radiocarbon-dated to c. 13 300–12 300 BP. In Siberia, the earliest pottery is known from the Ust-Karenga complex, dated to c. 11 200–10 800 BP. The Osipovka and Gromatukha complexes belong to the Initial Neolithic, and they are contemporaneous with the earliest Neolithic cultures in southern China and Japan. In spite of the very early emergence of pottery in the Russian Far East, there is no evidence of agriculture at the beginning of the Neolithic, and subsistence remains based on hunting and fishing, including anadromous salmonids in the Amur River and its tributaries.

BackgroundVirtually all well-documented remains of early domestic dog (Canis familiaris) come from the late Glacial and early Holocene periods (ca. 14,000-9000 calendar years ago, cal BP), with few putative dogs found prior to the Last Glacial Maximum (LGM, ca. 26,500-19,000 cal BP). The dearth of pre-LGM dog-like canids and incomplete state of their preservation has until now prevented an understanding of the morphological features of transitional forms between wild wolves and domesticated dogs in temporal perspective.Methodology/principal findingWe describe the well-preserved remains of a dog-like canid from the Razboinichya Cave (Altai Mountains of southern Siberia). Because of the extraordinary preservation of the material, including skull, mandibles (both sides) and teeth, it was possible to conduct a complete morphological description and comparison with representative examples of pre-LGM wild wolves, modern wolves, prehistoric domesticated dogs, and early dog-like canids, using morphological criteria to distinguish between wolves and dogs. It was found that the Razboinichya Cave individual is most similar to fully domesticated dogs from Greenland (about 1000 years old), and unlike ancient and modern wolves, and putative dogs from Eliseevichi I site in central Russia. Direct AMS radiocarbon dating of the skull and mandible of the Razboinichya canid conducted in three independent laboratories resulted in highly compatible ages, with average value of ca. 33,000 cal BP.Conclusions/significanceThe Razboinichya Cave specimen appears to be an incipient dog that did not give rise to late Glacial-early Holocene lineages and probably represents wolf domestication disrupted by the climatic and cultural changes associated with the LGM. The two earliest incipient dogs from Western Europe (Goyet, Belguim) and Siberia (Razboinichya), separated by thousands of kilometers, show that dog domestication was multiregional, and thus had no single place of origin (as some DNA data have suggested) and subsequent spread.
