Is there an 'aquatic' Neolithic?:New insights from organic residue analysis of early Holocene pottery from European Russia and Siberia

This thesis investigates the function of early Holocene hunter-gatherer ceramic vessels in northern Eurasia. It presents the first systematic application of organic residue analysis (ORA) to Early Neolithic pottery from European Russia and Siberia. During the early Holocene (ca. 9,700 to 5,000 cal BC) pottery was widely produced by hunter-gatherers across Eurasia. One existing theory suggests that the advent of pottery was linked to an intensification of aquatic resource exploitation; the so-called “Aquatic” Neolithic (Gibbs et al. 2017). This theory is supported by recent ORA of early pottery from eastern Asia and northern Europe, where lipid markers derived from aquatic resources were frequently encountered, absorbed in the pots themselves. One area neglected by ORA is the vast territory of what is now Russia where the arrival of pottery marks the start of the Neolithic period, predating agriculture by several thousand years. Despite its importance in defining the Neolithic in this region, little is known about how early pottery was used and what drove its adoption during the early Holocene. Here, ORA was applied to 417 samples, representing 314 ceramic vessels, recovered from three important early Neolithic sites: the East Siberian site of Gorelyi Les, and Rakushechny Yar and Zamostje 2 in the southern and northern part of European Russia respectively. Overall, the results generated by this thesis indicate much greater diversity in the use of early pottery than predicted from the “Aquatic” Neolithic theory. While aquatic products were indeed prevalent at many sites, lipids derived from terrestrial plants and animals were also common and, overall, the initial use of pottery seems to have varied according to the regional context. These results challenge the idea that the widespread adoption of pottery by Holocene Eurasian foragers was driven primarily by the need to process aquatic resources

Something fishy in the Great Lakes?:The reappraisal of early pottery use in north-eastern North America.

Lipid residue analysis has recently been applied to investigate the adoption of pottery by Early Woodland hunter-gatherers in north-eastern North America. Results, however, have proven contradictory, especially regarding the extent towhich early ceramics were used for processing aquatic resources. Here, the authors argue that this inconsistency is due to the use of different analytical procedures and criteria for identifying aquatic organisms, rather than anyactual variations in pottery use. By applying robust analytical criteria and methods to Early Woodland pottery from the Great Lakes region, the authors present evidence supporting their hypothesis that such pottery was indeed used for processing aquatic resource

Human palaeodiet at Zamostje 2, central Russia:Results of radiocarbon and stable isotope analyses

Only 21 human remains have been identified at Zamostje 2, despite extraordinarily good conditions for organic preservation, and the recovery of thousands of animal bones from layers dating from the Late Mesolithic to the Middle Neolithic (c.6500–4000 cal BC). Almost all the human remains are fragments of the cranium, maxilla, mandible, which are potentially reworked from earlier depositions, uphill or upstream of Zamostje 2, or isolated teeth. Disregarding naturally shed deciduous teeth, these remains have been attributed to between 5 and 14 individuals, ranging in age from 6 to 7 years to mature adult. We report AMS radiocarbon (14C) dating and dietary stable isotopes, δ13C and δ15N, for all the human bones, and δ13C and δ15N values from 63 prehistoric animal bones from Zamostje 2, including 18 fish and 7 dogs. Using the faunal isotope data, we construct isotope signatures for different food groups, which we use to interpret the human δ13C and δ15N values. Based on 14C ages and dietary stable isotopes, we propose that the human bones represent 10–12 individuals, most of whom date to the Late Mesolithic occupation at Zamostje 2; one is somewhat earlier in the Mesolithic, one (probably from the nearby site, Zamostje 1) may date to the Middle Neolithic, and two (one from Zamostje 1, one unprovenanced) date to the Late Neolithic or Eneolithic. The earliest and latest individuals may have obtained most of their dietary protein intake from fish, but Late Mesolithic individuals probably had more mixed diets. Palaeodiet reconstruction is complicated by unusual δ13C and δ15N values for local fish in the Late Mesolithic, which are reflected in δ13C and δ15N values from dogs

Resource Processing, Early Pottery and the Emergence of Kitoi Culture in Cis-Baikal:Insights from Lipid Residue Analysis of an Early Neolithic Ceramic Assemblage from the Gorelyi Les Habitation Site, Eastern Siberia

In the early Holocene, Mesolithic hunter-gatherer communities inhabiting the Cis-Baikal region of Eastern Siberia were participating in a series of important cultural changes. These included the establishment of large cemeteries in the Angara Valley and on the Southwest shores of Lake Baikal, culminating in the formation of the distinctive Early Neolithic Kitoi cultural pattern ca. 7560 cal. BP. Around the same time, the appearance of clay pots in a few Kitoi graves and at some contemporary habitation sites marks the formal transition to the Early Neolithic, which is defined in Russian archaeology by the emergence of pottery (and not the transition to farming). Little is known about how this early pottery was used, and why it was first adopted into the region. This pilot-study presents lipid-residue analysis of a selection of sherds from the oldest and relatively well-dated pottery assemblage in the Cis-Baikal region, which was recovered from the Gorelyi Les habitation site. The results indicate that the pots had been used to process a broad spectrum of food resources, including ruminants, fish and plants, and possibly resin and other by-products derived from pine trees, suggesting that the vessels were being used as general-purpose cooking containers. We conclude that there is scope for a much larger-scale investigation of diversity and change in prehistoric pottery use in Cis-Baikal, and that this research would improve current understandings of the diet, health and subsistence strategies of the Kitoi and other prehistoric populations

Investigating the formation and diagnostic value of ω-(o-alkylphenyl)alkanoic acids in ancient pottery

Long chain ω‐(o‐alkylphenyl)alkanoic acids (APAAs) derived from the heating of unsaturated fatty acids have been widely used for the identification of aquatic products in archaeological ceramic vessels. To date, little attention has been paid to the diagnostic potential of shorter chain (<C20) APAAs, despite their frequent occurrence. Here, a range of laboratory and field experiments and analyses of archaeological samples were undertaken to investigate whether APAAs could be used to further differentiate different commodities. The results of this study provide new insights regarding conditions for the formation of APAAs and enable us to propose novel criteria to distinguish different natural products

Neolithic farmers or Neolithic foragers? Organic residue analysis of early pottery from Rakushechny Yar on the Lower Don (Russia)

The emergence of pottery in Europe is associated with two distinct traditions: hunter-gatherers in the east of the continent during the early 6th millennium BC and early agricultural communities in the south-west in the late 7th millennium BC. Here we investigate the function of pottery from the site of Rakushechny Yar, located at the Southern fringe of Eastern Europe, in this putative contact zone between these two economic ‘worlds’. To investigate, organic residue analysis was conducted on 120 samples from the Early Neolithic phase (ca. mid-6th millennium BC) along with microscopic and SEM analysis of associated foodcrusts. The results showed that the earliest phase of pottery use was predominantly used to process riverine resources. Many of the vessels have molecular and isotopic characteristics consistent with migratory fsh, such as sturgeon, confrmed by the identifcation of sturgeon bony structures embedded in the charred surface deposits. There was no evidence of dairy products in any of the vessels, despite the fact these have been routinely identifed in coeval sites to the south. Further analysis of some of the mammalian bones using ZooMS failed to demonstrate that domesticated animals were present in the Early Neolithic. Nevertheless, we argue that intensive exploitation of seasonally migratory fsh, accompanied by large-scale pottery production, created storable surpluses that led to similar socio-economic outcomes as documented in early agricultural societies

The use of early pottery by hunter-gatherers of the Eastern European forest-steppe

The Eastern European steppe and forest-steppe is a key region for understanding the emergence of pottery in Europe. The vast region encompasses the basins of two major waterways, the Don and the Volga rivers, and was occupied by hunter-gatherer-fisher communities attracted to highly productive forest/aquatic ecotones. The precise dates for the inception of pottery production in this region and the function of pottery is unknown, but such information is vital for charting the pan-Eurasian dispersal of pottery technology and whether there were common motivations for its adoption. To investigate, we conducted AMS dating, including a re-evaluation of legacy radiocarbon dates together with organic residue analysis and microscopy. The dating programme was able to clarify the sequence and show that hunter-gatherer pottery production was unlikely in this region before the 6th millennium BC. Regarding use, stable isotope and molecular analysis of 160 pottery samples from 35 sites across the region shows that terrestrial animal carcass fats were preferentially processed in pots at Middle Volga sites whereas aquatic resources dominate the residues in pottery from the Middle and Upper Don basin. This is supported by fragments of fish, legumes and grasses in the available charred deposits adhering to the inside of pottery from the Don basin. Since the sites from both river basins had similar environmental settings and were broadly contemporaneous, it is posited that pottery use was under strong cultural control, recognisable as separate sub-regional culinary traditions. The ‘aquatic hypothesis’, previously suggested to explain the emergence of Eurasian pottery, cannot be substantiated in this context

Chemical analysis of pottery reveals the transition from a maritime to a plant-based economy in pre-colonial coastal Brazil

Understanding long-term dynamics of past socio-ecological systems is essential for their future management. The southern Atlantic Forest coast of Brazil with its biodiverse littoral zone and artisanal fishing communities, is a priority for conservation. Traditional maritime knowledge is thought to have a deep-history and indeed, marine exploitation can be traced back to the middle Holocene. As part of one of South America’s largest diasporas, Guarani groups reached the southern Brazilian coast at around 1000 years ago. Their impact on the long-standing coastal economy is unknown, due to poor preservation of organic remains. Through the first organic residue study on Guarani pottery, we show that maize rather than aquatic foods was the most dominant product in pottery at this time. By developing a mixing model based on carbon isotope values of saturated and mono-unsaturated fatty acids we propose new criteria for the identification of maize, opening up avenues for future research. Our data confirms the importance of maize to the pre-colonial Guarani, even in a highly productive coastal environment. The Guarani occupation of this region marks a significant departure from previous socio-economic systems, potentially leading to loss of traditional knowledge and alleviating anthropogenic pressure, albeit temporarily, on the marine environment

The transmission of pottery technology among prehistoric European hunter-gatherers

Human history has been shaped by global dispersals of technologies, although understanding of what enabled these processes is limited. Here, we explore the behavioural mechanisms that led to the emergence of pottery among hunter-gatherer communities in Europe during the mid-Holocene. Through radiocarbon dating, we propose this dispersal occurred at a far faster rate than previously thought. Chemical characterization of organic residues shows that European hunter-gatherer pottery had a function structured around regional culinary practices rather than environmental factors. Analysis of the forms, decoration and technological choices suggests that knowledge of pottery spread through a process of cultural transmission. We demonstrate a correlation between the physical properties of pots and how they were used, reflecting social traditions inherited by successive generations of hunter-gatherers. Taken together the evidence supports kinship-driven, super-regional communication networks that existed long before other major innovations such as agriculture, writing, urbanism or metallurgy
