The History of Archaeobotanical Practice in China
This chapter traces developments in the study of ancient plant remains in China over the last century with a particular focus on the last 40 years. Although analyses of ancient plant remains in China occurred in the 1960s, archaeobotany developed into a fully-fledged discipline only after the turn of the 21st century. We illustrate the main actors in the establishment and development of the discipline in China, the development of research trends,…
The linguistic (pre)history on the eastern Tibetan Plateau
The early dispersal of Sino-Tibetan language family has been proposed to be promoted by millet domestication and cultivation, and ultimately agricultural development in the Yellow River Valley. However, the spread of Sino-Tibetan onto the Tibetan Plateau was a more complex picture showing interactions between the agriculturalists from the Yellow River region and the local hunter-gatherers. This article investigates exchange and contact dynamics o…
Differences in the isotopic composition of individual grains and aggregated seed samples affect interpretation of ancient plant cultivation practices
The stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope analysis of charred archaeological grains provides a remarkably precise scale of information: the growing conditions under which a plant was cultivated in a single field and season. Here we investigate how the measurement of single individual grains or aggregate “bulk” samples for carbon and nitrogen isotopes impacts how we characterize variation and, consequently, our interpretations of an…
Taphonomy and labour at the Indus Valley site of Harappa (3700-1300 BC)
The emergence of early cities required new agricultural practices and archaeobotanical crop-processing models have been used to investigate the social and economic organisation of urban 'consumer' and non-urban 'producer' sites. Archaeobotanical work on the Indus Valley has previously identified various interpretations of labour and subsistence practices. Here, the authors analyse a large archaeobotanical assemblage from Harappa, Pakistan (3700-1…
New Evidence for Prehistoric Textile Production and Social Complexity on the Southeastern Tibetan Plateau, Southwestern China
Homeland Food Traditions in the Tiwanaku Colonies
The Tiwanaku civilization (around AD 500-1100) originated in the Bolivian altiplano of the south-central Andes and established agrarian colonies (AD 600-1100) in the Peruvian coastal valleys. Current dietary investigations at Tiwanaku colonial sites focus on maize, a coastal valley cultivar with ritual and political significance. Here, we examine Tiwanaku provincial foodways and ask to what degree the Tiwanaku settlers maintained their culinary a…
Implications of the loess record for Holocene climate and human settlement in Heye Catchment, Jiuzhaigou, eastern Tibetan Plateau, Sichuan, China
We examine the Holocene loess record in the Heye Catchment on the margins of the Tibetan Plateau (TP) and China Loess Plateau (CLP) to determine: the region to which the Heye Catchment climate is more similar; temporal change in wind strength; and modification of the loess record by mass wasting and human activity. Luminescence and radiocarbon dating demonstrate loess deposited in two periods: >11–8.6 ka and
Sichuan Peppercorn and the Birth of Numbing Spices in East Asia
Sichuan peppercorn Zanthoxylum sp. is an important food condiment, currently used in East Asia and South Asia. In this paper, we review genetic, archaeological, and linguistic evidence regarding the use of Zanthoxylum by ancient human populations. The evidence from these three disciplines converge to suggest that its earliest attested use dates from the mid-fourth millennium BCE, in Western Sichuan, making it one of the oldest spices in East Asia…
Northwest Native Plants
Biocultural heritage preservation relies on ethnobotanical knowledge and the paleoethnobotanical data used in (re)constructing histories of human–biota interactions. Biocultural heritage, defined as the knowledge and practices of Indigenous and local peoples and their biological relatives, is often guarded information, meant for specific audiences and withheld from other social circles. As such, these forms of heritage and knowledge must also be …

Monsoon Rains, Great Rivers and the Development of Farming Civilisations in Asia
The Asian monsoon and associated river systems supply the water that sustains a large portion of humanity, and has enabled Asia to become home to some of the oldest and most productive farming systems on Earth. This book uses climate data and environmental models to provide a detailed review of variations in the Asian monsoon since the mid-Holocene, and its impacts on farming systems and human settlement. Future changes to the monsoon due to anth…
Yak Domestication
Yak, a species of bovid uniquely adapted to high-altitude environments, plays a critical role in the life of the inhabitants of the Tibetan Plateau and neighboring areas. There is currently no consensus on when these animals may have been domesticated. In this paper, we review the archaeological, genetic, and linguistic evidence relevant to this question, and suggest that the domestication took place following hybridization with taurine cattle fr…

Complex Pathways Towards Emergent Pastoral Settlements
The Xindian culture of northwest China has been seen as a prototypical example of a transition toward pastoralism, resulting in part from environmental changes that started around 4000 years ago. To date, there has been little available residential data to document how and whether subsistence strategies and community organization in northwest China changed following or in association with documented environmental changes. The Tao River Archaeolog…

Resistance and Care in the Time of Covid-19
The COVID-19 pandemic offered humanity a portal through which we could break with the past and imagine our world anew. This article reviews how over the course of 2020, a series of intersecting crises at the nexus of racism, settler colonialism, climate change, and sexual harassment have prompted acts of resistance and care in the field of archaeology. Throughout the article, we provide concrete suggestions as to how we can continue the work of m…
Foraging and farming
Archaeological research has documented the migration of Neolithic farmers onto the Tibetan Plateau by 4000 BC. How these incoming groups interacted, if at all, with local indigenous foragers, however, remains unclear. New archaeobotanical and zooarchaeological data from the Zongri site in the north-eastern Tibetan Plateau suggest that local foragers continued to hunt but supplemented their diet with agricultural products in the form of millet. Th…
A prehistoric copper-production centre in central Thailand
The Khao Wong Prachan Valley of central Thailand is one of four known prehistoric loci of copper mining, smelting and casting in Southeast Asia. Many radiocarbon determinations from bronze-consumption sites in north-east Thailand date the earliest copper-base metallurgy there in the late second millennium BC. By applying kernel density estimation analysis to approximately 100 new AMS radiocarbon dates, the authors conclude that the valley's first…
Three thousand years of farming strategies in central Thailand
In prehistoric coastal and western-central Thailand, rice was the dominant cultivar. In eastern-central Thailand, however, the first known farmers cultivated millet. Using one of the largest collections of archaeobotanical material in Southeast Asia, this article examines how cropping systems were adapted as domesticates were introduced into eastern-central Thailand. The authors argue that millet reached the region first, to be progressively repl…

Gendered Places and Depositional Histories
This project considered the deposition history of a burned structure located on the Kalispel Tribe of Indians ancestral lands at the Flying Goose site in northeastern Washington. Excavation of the structure revealed stratified deposits that do not conform to established Columbia Plateau architectural types. The small size, location, and absence of artifacts lead us to hypothesize that this site was once a non-domestic structure. We tested this hy…
Did foragers adopt farming? A perspective from the margins of the Tibetan Plateau
Landscapes of Prehistoric Northwestern Sichuan
We describe a preliminary survey of a relatively unknown part of the eastern Himalayas: northwestern Sichuan. This survey revealed that three phases of occupation are represented across the landscape. Large settlements with dense remains characterize the landscape during the Neolithic (3400–2000 cal b.c.). Following a hiatus in occupation, stone-cist graves characterize the region during the Bronze Age (1450–800 cal b.c.). The lack of settlement …
Moving agriculture onto the Tibetan plateau
A 5,500-Year Model of Changing Crop Niches on the Tibetan Plateau
The timing and mechanics of the spread of agriculture to the Tibetan Plateau-one of the most challenging environmental contexts on earth-is a focus of recent work and debate. Understanding the timing and spread of agriculture is basic to archaeology and history worldwide. Researchers seek evidence for the earliest, furthest, or highest occurrences of diagnostic elements. However, the Tibetan Plateau case illustrates a key flaw in current work: ar…
Rethinking the spread of agriculture to the Tibetan Plateau
New data from the Tibetan Plateau allow us to understand how populations dealt with the challenges of moving crops into altitudinally constrained environments. Despite the interest in explaining the timing and the mechanisms via which agricultural products spread to the roof of the world, current models for the spread of agriculture to this region have been simplistic and the presence of crop domesticates is often straightforwardly interpreted as…

Site of Baodun yields earliest evidence for the spread of rice and foxtail millet agriculture to south-west China
The Chengdu plain of south-west China lies outside the main centres of early domestication in the Huanghe and Yangzi valleys, but its importance in Chinese prehistory is demonstrated by the spectacular Sanxingdui bronzes of the second millennium BC and by the number of walled enclosures of the third millennium BC associated with the Baodun culture. The latter illustrate the development of social complexity. Paradoxically, however, these are not t…

We present a critique of a paper written by two economists, Quamrul Ashraf and Oded Galor, which is forthcoming in the American Economic Review and which was uncritically highlighted in Science magazine. Their paper claims there is a causal effect of genetic diversity on economic success, positing that too much or too little genetic diversity constrains development. In particular, they argue that "the high degree of diversity among African popula…

Lost Foraging Opportunities for East Asian Hunter‐Gatherers Due to Rising Sea Level Since the Last Glacial Maximum
This paper explores how changes in sea level and biome distribution may have affected the habitats occupied by hunter‐gatherers in East Asia. Using a model‐based reconstruction of changing sea level from the Last Glacial Maximum (LGM) to present day, our analysis reveals that the exposure of a large continental shelf during the LGM sea level lowstand created a wealth of wooded, estuarine, and coastal biomes that could have been exploited intensiv…

Early evidence for the use of wheat and barley as staple crops on the margins of the Tibetan Plateau
Significance Adapting agricultural systems to the high-altitude environment of the Tibetan Plateau has long been considered a major challenge for farmers. It has been asserted previously that the ecological characteristics of wheat and barley delayed their spread into East Asia. We argue instead that the ability of these crops to tolerate frost and their low heat requirements facilitated their spread into the high-altitude margins of western Chin…

Twenty-first century approaches to ancient problems
By documenting how humans adapted to changes in their environment that are often much greater than those experienced in the instrumental record, archaeology provides our only deep-time laboratory for highlighting the circumstances under which humans managed or failed to find to adaptive solutions to changing climate, not just over a few generations but over the longue durée . Patterning between climate-mediated environmental change and change in …
