Dairying enabled Early Bronze Age Yamnaya steppe expansions
Shevan Wilkin et al.
Nature, forthcoming

Abstract:
During the Early Bronze Age, populations of the western Eurasian steppe expanded across an immense area of northern Eurasia. Combined archaeological and genetic evidence supports widespread Early Bronze Age population movements out of the Pontic–Caspian steppe that resulted in gene flow across vast distances, linking populations of Yamnaya pastoralists in Scandinavia with pastoral populations (known as the Afanasievo) far to the east in the Altai Mountains and Mongolia. Although some models hold that this expansion was the outcome of a newly mobile pastoral economy characterized by horse traction, bulk wagon transport and regular dietary dependence on meat and milk, hard evidence for these economic features has not been found. Here we draw on proteomic analysis of dental calculus from individuals from the western Eurasian steppe to demonstrate a major transition in dairying at the start of the Bronze Age. The rapid onset of ubiquitous dairying at a point in time when steppe populations are known to have begun dispersing offers critical insight into a key catalyst of steppe mobility. The identification of horse milk proteins also indicates horse domestication by the Early Bronze Age, which provides support for its role in steppe dispersals. Our results point to a potential epicentre for horse domestication in the Pontic–Caspian steppe by the third millennium BC, and offer strong support for the notion that the novel exploitation of secondary animal products was a key driver of the expansions of Eurasian steppe pastoralists by the Early Bronze Age. 


Pandemic Spikes and Broken Spears: Indigenous Resilience after the Conquest of Mexico
Alberto Diaz-Cayeros, Juan Espinosa-Balbuena & Saumitra Jha
Stanford Working Paper, August 2021

Abstract:
It is well-established that the Conquest of the Americas by Europeans led to catastrophic declines in indigenous populations. However, less is known about the conditions under which indigenous communities were able to overcome the onslaught of disease and violence that they faced. Drawing upon a rich set of sources, including Aztec tribute rolls and early Conquest censuses, we develop a new disaggregated dataset on the pre-Conquest economic, epidemiological and political conditions both in 11,888 potential settlement locations in the historic core of Mexico and specifically in 1093 actual settlements recorded in an early Conquest-era census, the Suma de Visitas (1548). Of these 1093 settlements, we show that 37% had disappeared entirely by 1790. Yet, despite being subject to Conquest-era violence, subsequent coercion and multiple pandemics that led average populations in those settlements to fall from 2377 to 128 by 1646, 13% would still end the colonial era larger than they started. We show that both indigenous settlement survival durations and population levels through the colonial period are robustly predicted, not just by Spanish settler choices or by their diseases, but also by the extent to which indigenous communities could themselves leverage nonreplicable and non-expropriable resources and skills from the pre-Columbian period that would prove complementary to global trade. Thus indigenous opportunities and agency played important roles in shaping their own resilience. 


Barbarigenesis and the collapse of complex societies: Rome and after
Doug Jones
PLoS ONE, September 2021 

Abstract:
“Barbarism” is perhaps best understood as a recurring syndrome among peripheral societies in response to the threats and opportunities presented by more developed neighbors. This article develops a mathematical model of barbarigenesis — the formation of “barbarian” societies adjacent to more complex societies — and its consequences, and applies the model to the case of Europe in the first millennium CE. A starting point is a game (developed by Hirshleifer) in which two players allocate their resources either to producing wealth or to fighting over wealth. The paradoxical result is that a richer and potentially more powerful player may lose out to a poorer player, because the opportunity cost of fighting is greater for the former. In a more elaborate spatial model with many players, the outcome is a wealth-power mismatch: central regions have comparatively more wealth than power, peripheral regions have comparatively more power than wealth. In a model of historical dynamics, a wealth-power mismatch generates a long-lasting decline in social complexity, sweeping from more to less developed regions, until wealth and power come to be more closely aligned. This article reviews how well this model fits the historical record of late Antiquity and the early Middle Ages in Europe both quantitatively and qualitatively. The article also considers some of the history left out of the model, and why the model doesn’t apply to the modern world. 


Parental relatedness through time revealed by runs of homozygosity in ancient DNA
Harald Ringbauer, John Novembre & Matthias Steinrücken
Nature Communications, September 2021

Abstract:
Parental relatedness of present-day humans varies substantially across the globe, but little is known about the past. Here we analyze ancient DNA, leveraging that parental relatedness leaves genomic traces in the form of runs of homozygosity. We present an approach to identify such runs in low-coverage ancient DNA data aided by haplotype information from a modern phased reference panel. Simulation and experiments show that this method robustly detects runs of homozygosity longer than 4 centimorgan for ancient individuals with at least 0.3 × coverage. Analyzing genomic data from 1,785 ancient humans who lived in the last 45,000 years, we detect low rates of first cousin or closer unions across most ancient populations. Moreover, we find a marked decay in background parental relatedness co-occurring with or shortly after the advent of sedentary agriculture. We observe this signal, likely linked to increasing local population sizes, across several geographic transects worldwide. 


Marckalada: The First Mention of America in the Mediterranean Area (c. 1340)
Paolo Chiesa
Terrae Incognitae: The Journal of the Society for the History of Discoveries, Summer 2021, 88-106

Abstract:
The Cronica universalis written by the Milanese friar Galvaneus Flamma (it. Galvano Fiamma, d. c. 1345) contains an astonishing reference to a terra que dicitur Marckalada, situated west from Greenland. This land is recognizable as the Markland mentioned by some Icelandic sources and identified by scholars as some part of the Atlantic coast of North America. Galvaneus’s reference, probably derived by oral sources heard in Genoa, is the first mention of the American continent in the Mediterranean region, and gives evidence of the circulation (out of the Nordic area and 150 years before Columbus) of narratives about lands beyond Greenland. This article provides a transcription of the passage, explains its context in the Cronica universalis, compares it to the other (Nordic) references of Markland, and discusses the possible origin of Galvaneus’s mention of Markland in light of Galvaneus’s biography and working method.


Made for exchange: The Russian Karelian lithic industry and hunter-fisher-gatherer exchange networks in prehistoric north-eastern Europe
Alexey Tarasov & Kerkko Nordqvist
Antiquity, forthcoming

Abstract:

The hunter-fisher-gatherers of fourth- to third-millennium BC north-eastern Europe shared many characteristics traditionally associated with Neolithic and Chalcolithic agricultural societies. Here, the authors examine north-eastern European hunter-fisher-gatherer exchange networks, focusing on the Russian Karelian lithic industry. The geographically limited, large-scale production of Russian Karelian artefacts for export testifies to the specialised production of lithic material culture that was exchanged over 1000km from the production workshops. Functioning both as everyday tools and objects of social and ritual engagement, and perhaps even constituting a means of long-distance communication, the Russian Karelian industry finds parallels with the exchange systems of contemporaneous European agricultural populations. 


A worked bone assemblage from 120,000–90,000 year old deposits at Contrebandiers Cave, Atlantic Coast, Morocco
Emily Hallett et al.
iScience, September 2021

Abstract:The emergence of Homo sapiens in Pleistocene Africa is associated with a profound reconfiguration of technology. Symbolic expression and personal ornamentation, new tool forms, and regional technological traditions are widely recognized as the earliest indicators of complex culture and cognition in humans. Here we describe a bone tool tradition from Contrebandiers Cave on the Atlantic coast of Morocco, dated between 120,000–90,000 years ago. The bone tools were produced for different activities, including likely leather and fur working, and were found in association with carnivore remains that were possibly skinned for fur. A cetacean tooth tip bears what is likely a combination of anthropogenic and non-anthropogenic modification and shows the use of a marine mammal tooth by early humans. The evidence from Contrebandiers Cave demonstrates that the pan-African emergence of complex culture included the use of multiple and diverse materials for specialized tool manufacture.
