•Arboriculture in the Iberian peninsula dates back to the beginning of the 1st millennium BC.•The adoption of fruit tree cultivation is part of the process of social complexity.•A large collection of ...fruit remains has been dated.
Agricultural activities, including practices, crops and techniques have evolved throughout history undergoing tremendous changes. From the early Neolithic farmers in the Mediterranean focused on cereal agriculture and only later, during the 4th/3rd millennium cal. BC in the Eastern basin, other species such as fruit trees were introduced into the agrarian system transforming the model that had been in use for millennia. Fruit tree management required innovation and investment and more importantly multi-year foresight as the new crops entailed a new pace of work with delayed returns and, thus, a greater entanglement with the land. Processes of social complexity and urbanization accompanied the emergence of arboriculture which occurred at different pace at both ends of the Mediterranean. This paper focuses on the Iberian Peninsula, the most western Mediterranean region, during the 1st millennium cal. BC when arboriculture spread after commercial encounters with oriental seafarers. Here we report the earliest archaeobotanical evidence (seeds and fruits) for the introduction of fruit cultivation in Iberia. Results from several sites indicate that the spread of fruit cultivation was a long process that varied regionally. In some areas the new crops were rapidly adopted and integrated into the Mediterranean trading networks while in other regions arboriculture was not developed until the end of the millennium. Of the various fruit products that were commercialized, wine occupied a most relevant role.
Rach Nui is a late Neolithic settlement of hunter-gatherers in southern Vietnam. However, the site also has a series of mortared floors corresponding to a sedentary lifestyle, where the inhabitants ...continued to live in the same area and repaired or replaced their floors over a period of 150 years. The inhabitants relied on a mixed economy that included domesticated and gathered plants, as well as hunted and managed animals. Although, there is evidence for the consumption of domesticated rice and foxtail millet, the inhabitants were mainly hunter-gatherers who relied on their surrounding mangrove and swamp forest habitats for most of their food requirements. From the archaeobotanical work done, it appears that the domesticated cereals, rice and foxtail millet, found at the site were imported. On the other hand, sedge nutlets and parenchyma were identified in high frequencies and were probably locally sourced, suggesting that foraging and/or vegeculture played a major role in the economy of Rach Nui.
As a specialised branch of archaeology requiring specific field and laboratory methodologies, the contributions of archaeobotany have often been overlooked by the ecological research community. ...Developments in the fields of botany, chemistry, and ancient DNA analyses have greatly increased the potential for archaeobotany to contribute to topical questions relating to the Anthropocene and landscape transformations. We review the role of archaeobotany in identifying and describing past arable land use. Analytical techniques are illustrated with examples at both local and regional scales, demonstrating how archaeobotany can provide unique details of the wide array of past subsistence and land-use strategies. These data and their potential should be better recognised as important information that could underpin models seeking to evaluate or predict the effects of socioenvironmental interactions.
Ancient plant remains hold information on past subsistence strategies and land use.Recent advances in the field of archaeobotany have broadened the range of techniques by which ancient plant remains can be studied.Archaeobotanical investigations show a diverse range of ancient farming practices and innovative solutions to social and natural pressures.Descriptions of ancient land use could be integrated into models of human–environment interactions, thus enabling a more accurate understanding of the impacts of past practices, and providing potential lessons for the future.
The ancient DNA revolution of the past 35 years has driven an explosion in the breadth, nuance, and diversity of questions that are approachable using ancient biomolecules, and plant research has ...been a constant, indispensable facet of these developments. Using archaeological, paleontological, and herbarium plant tissues, researchers have probed plant domestication and dispersal, plant evolution and ecology, paleoenvironmental composition and dynamics, and other topics across related disciplines. Here, we review the development of the ancient DNA discipline and the role of plant research in its progress and refinement. We summarize our understanding of long-term plant DNA preservation and the characteristics of degraded DNA. In addition, we discuss challenges in ancient DNA recovery and analysis and the laboratory and bioinformatic strategies used to mitigate them. Finally, we review recent applications of ancient plant genomic research.
The development of oppida in the late first millennium BC across north-western Europe represents a major change in settlement form and social organisation. The construction of extensive earthwork ...systems, the presence of nucleated settlement areas, long-distance trade links and the development of hierarchical societies have been evidenced. These imply that changes in the style and organisation of agriculture would have been required to support these proto-urban population centres. Hypotheses of the subsistence bases of these settlements, ranging from a reliance on surplus arable production from local rural settlements, to an emphasis on pastoral activities, are here reviewed and grounded against a wider understanding of the expansion of agriculture in the Late Iron Age. These agricultural models have not been previously evaluated.
This paper presents archaeobotanical data from six well fills from large-scale excavations at Late Iron Age and Early Roman Silchester, a Late Iron Age territorial oppidum and subsequent Roman civitas capital located in central-southern Britain. This is the first large-scale study of waterlogged plant macrofossils from within a settlement area of an oppidum. Waterlogged plant macrofossils were studied from a series of wells within the settlement. An assessment of taphonomy, considering stratigraphic and contextual information, is reported, followed by an analysis of the diverse assemblages of the plant remains through univariate analysis. Key results evidence animal stabling, flax cultivation, hay meadow management and the use of heathland resources. The staple crops cultivated and consumed at Late Iron Age and Early Roman Silchester are consistent with those cultivated in the wider region, whilst a range of imported fruits and flavourings were also present. The adoption of new oil crops and new grassland management shows that agricultural innovations were associated with foddering for animals rather than providing food for the proto-urban population. The evidence from Silchester is compared with other archaeobotanical datasets from oppida in Europe in order to identify key trends in agricultural change.
The earliest evidence of agriculture in the Horn of Africa dates to the Pre-Aksumite period (ca. 1600 BCE). Domesticated C3 cereals are considered to have been introduced from the Near East, whereas ...the origin (local or not) and time of domestication of various African C4 species such as sorghum, finger millet, or t'ef remain unknown. In this paper, we present the results of the analysis of microbotanical residues (starch and phytoliths) from grinding stones recovered from two archaeological sites in northeastern Tigrai (Ethiopia), namely Mezber and Ona Adi. Together, both sites cover a time period that encompasses the earliest evidence of agriculture in the region (ca. 1600 BCE) to the fall of the Kingdom of Aksum (ca. 700 CE). Our data indicate that these communities featured complex mixed economies which included the consumption of both domestic and wild plant products since the Initial Pre-Aksumite Phase (ca. 1600 to 900 BCE), including C3 crops and legumes, but also C4 cereals and geophytes. These new data expand the record of C4 plant use in the Horn of Africa to over 1,000 y. It also represents the first evidence for the consumption of starchy products in the region. These results have parallels in the wider northeastern African region where complex food systems have been documented. Altogether, our data represent a significant challenge to our current knowledge of Pre-Aksumite and Aksumite economies, forcing us to rethink the way we define these cultural horizons.
The complex evolutionary history of maize (Zea mays L. ssp. mays) has been clarified with genomic-level data from modern landraces and wild teosinte grasses 1, 2, augmenting archaeological findings ...that suggest domestication occurred between 10,000 and 6,250 years ago in southern Mexico 3, 4. Maize rapidly evolved under human selection, leading to conspicuous phenotypic transformations, as well as adaptations to varied environments 5. Still, many questions about the domestication process remain unanswered because modern specimens do not represent the full range of past diversity due to abandonment of unproductive lineages, genetic drift, on-going natural selection, and recent breeding activity. To more fully understand the history and spread of maize, we characterized the draft genome of a 5,310-year-old archaeological cob excavated in the Tehuacan Valley of Mexico. We compare this ancient sample against a reference panel of modern landraces and teosinte grasses using D statistics, model-based clustering algorithms, and multidimensional scaling analyses, demonstrating the specimen derives from the same source population that gave rise to modern maize. We find that 5,310 years ago, maize in the Tehuacan Valley was on the whole genetically closer to modern maize than to its wild counterpart. However, many genes associated with key domestication traits existed in the ancestral state, sharply contrasting with the ubiquity of derived alleles in living landraces. These findings suggest much of the evolution during domestication may have been gradual and encourage further paleogenomic research to address provocative questions about the world’s most produced cereal.
•Researchers characterized genome of a 5,310-year-old maize cob•The ancient maize genome is a basal lineage equally related to modern landraces•There is genetic evidence of naked kernels 5,310 years ago in Tehuacan, Mexico•Human selection on maize domestication traits occurred as a gradual process
Ramos-Madrigal et al. sequence the genome of 5,310-year-old maize cob, which represents a basal lineage equally related to all modern varieties. They provide an in-depth genomic characterization of maize at an early point during its evolution as a domesticate, suggesting that human selection occurred as a gradual process.
Recovery of archaeobotanical assemblages from Late Chalcolithic Bakla Tepe and Liman Tepe in western Anatolia has provided the opportunity for in-depth analysis of agricultural strategies and the ...organisation of farming-related activity at the two sites. We find that Late Chalcolithic farmers utilised five major crop taxa, potentially including two mixed crops. The two sites also provide the first evidence for Spanish vetchling and winged vetchling cultivation in prehistoric Anatolia and the earliest evidence for this practice to date anywhere. We suggest that the settlements were organised into small, co-residential households that processed and stored their own crops, but we also propose that potentially communal extra-household storage and high levels of social monitoring may attest to supra-household cooperation. The later agricultural history of the vetchling species and the prevalence of extra-household storage at sites in coastal western Anatolia and the eastern Aegean islands add to evidence for a cultural koine between these regions in the fourth and third millennia bc. We also suggest that the large size of extra-household storage structures and the narrow range of crops cultivated at some Late Chalcolithic sites are consistent with the emergence of more extensive farming systems than those of earlier periods. Evidence for the use of extensive agricultural production to amass arable wealth by the citadel elites of later Early Bronze Age western Anatolia suggests that the agro-ecological foundations for emergent wealth inequality within the region were laid during the Late Chalcolithic. Testing this hypothesis through direct evidence for the nature of Late Chalcolithic farming systems is a key aim of ongoing research.
