Archaeobotanical and isotope studies evidence crop cultivation already during the Early Iron Age in the boreal forests of the cis-Urals (Kama river basin)
摘要
The boreal forests represented a climatic and ecological challenge for early farmers. While in the boreal zone of Scandinavia evidence of agriculture dates back to the Neolithic, in Western Siberia cereal cultivation started not before the Middle Ages. Here we present the first comprehensive archaeobotanical investigation of archaeological sites from the mid-Kama region of easternmost Europe from the Early Iron Age and Medieval period. The results show that the emergence of agriculture occurred during the Late Ananyino period of the Early Iron Age, the latest in the 4th century bce. Most probably slash-and-burn agriculture was practiced, which very likely included manuring with dung. At that time, 58°N represented the northern border of crop cultivation in Eastern Europe. The main types of cultivated cereals were emmer and barley, which were diversified in the 3rd–5th centuries ce with bread wheat, broomcorn millet and hemp. Wild plants contributed to a diverse diet and indicate strongly altered landscapes around the study sites. The Early Iron Age dominance of emmer connects the origin of agriculture in the mid-Kama region to the Pontic steppe and Caucasus area. Overall, agriculture might have contributed to the increase in Glyadenovo population and occupation of new territories to the north and to the south.
