Early Life
The Origins of Enduring Economic Inequality
Samuel Bowles & Mattia Fochesato
Journal of Economic Literature, December 2024, Pages 1475-1537
Abstract:
We survey archaeological evidence suggesting that among hunter-gatherers and farmers in Neolithic western Eurasia (11,700 to 5,300 years ago) elevated levels of wealth inequality occurred but were ephemeral and rare compared to the substantial enduring inequalities of the past five millennia. In response, we seek to understand not the de novo "creation of inequality" but instead the processes by which substantial wealth differences could persist over long periods and why this occurred only at the end of the Neolithic, at least four millennia after the agricultural revolution. Archaeological and anthropological evidence suggests that a culture of aggressive egalitarianism may have thwarted the emergence of enduring wealth inequality until the Late Neolithic, when new farming technologies raised the value of material wealth relative to labor and a concentration of elite power in early proto-states (and eventually the exploitation of enslaved labor) provided the political and economic conditions for heightened wealth inequalities to endure.
Earliest modern human genomes constrain timing of Neanderthal admixture
Arev Sümer et al.
Nature, forthcoming
Abstract:
Modern humans arrived in Europe more than 45,000 years ago, overlapping at least 5,000 years with Neanderthals. Limited genomic data from these early modern humans have shown that at least two genetically distinct groups inhabited Europe, represented by Zlatý kůň, Czechia and Bacho Kiro, Bulgaria. Here we deepen our understanding of early modern humans by analyzing one high-coverage genome and five low-coverage genomes from ~45,000 year-old remains from Ilsenhöhle in Ranis, Germany, and a further high-coverage genome from Zlatý kůň. We show that distant familial relationships link the Ranis and Zlatý kůň individuals and that they were part of the same small, isolated population that represents the deepest known split from the Out-of-Africa lineage. Ranis genomes harbor Neanderthal segments that originate from a single admixture event shared with all non-Africans that we date to ~45,000-49,000 years ago. This implies that ancestors of all non-Africans sequenced to-date resided in a common population at this time, and further suggests that modern human remains older than 50,000 years from outside Africa represent different non-African populations.
Neanderthal ancestry through time: Insights from genomes of ancient and present-day humans
Leonardo Iasi et al.
Science, 13 December 2024
Abstract:
Gene flow from Neanderthals has shaped genetic and phenotypic variation in modern humans. We generated a catalog of Neanderthal ancestry segments in more than 300 genomes spanning the past 50,000 years. We examined how Neanderthal ancestry is shared among individuals over time. Our analysis revealed that the vast majority of Neanderthal gene flow is attributable to a single, shared extended period of gene flow that occurred between 50,500 to 43,500 years ago, as evidenced by ancestry correlation, colocalization of Neanderthal segments across individuals, and divergence from the sequenced Neanderthals. Most natural selection -- positive and negative -- on Neanderthal variants occurred rapidly after the gene flow. Our findings provide new insights into how contact with Neanderthals shaped modern human origins and adaptation.
Recycling and repair on the Roman frontier: A hoard of mail armour from Bonn
Martijn Wijnhoven, Claudia Koppmann & Holger Becker
Antiquity, December 2024, Pages 1592-1609
Abstract:
The Roman army was a vast military machine that demanded huge amounts of material and complex supply mechanisms. A 14kg hoard of mail armour from near the Roman legionary fortress of Bonn, Germany, offers insight into the organisation of recycling and repair on Rome's northern frontier. Computed tomography reveals there are at least four garments and suggests a likely date. The authors explore the hoard's context and motivations for its deposition and non-retrieval, arguing it formed a collection of 'donor' mail for repairing other mail garments. Its discovery in a settlement outside the military fortress indicates the involvement of local craftworkers. The settlement was abandoned in the mid-third century AD.
Monumental farmhouses and powerful farmers in Late Neolithic Denmark
Jens Winther Johannsen
Antiquity, December 2024, Pages 1522-1537
Abstract:
During the Late Neolithic, a series of short-lived, monumental-scale farmhouses were constructed across southern Scandinavia. The size of these structures is often taken as a tangible manifestation of the elite status of the inhabitants. Here, the author explores the architecture and associated material culture of the six largest known examples, drawing attention to general parallels with smaller farmhouses in the region. The comparison highlights similarities in spatial organisation and function indicating that, despite their size, these monumental houses served the same roles as dwellings and centres of agricultural production. Attention to function rather than size emphasises the importance of food production and control of surpluses in the emergence of social elites at the end of the Neolithic.
