Linguistic and genetic data have been widely compared, but the histories underlying these descriptions are rarely jointly inferred. We developed a unique methodological framework for analysing jointly language diversity and genetic polymorphism data, to infer the past history of separation, exchange and admixture events among human populations. This method relies on approximate Bayesian computations that enable the identification of the most probable historical scenario underlying each type of data, and to infer the parameters of these scenarios. For this purpose, we developed a new computer program PopLingSim that simulates the evolution of linguistic diversity, which we coupled with an existing coalescent-based genetic simulation program, to simulate both linguistic and genetic data within a set of populations. Applying this new program to a wide linguistic and genetic dataset of Central Asia, we found several differences between linguistic and genetic histories. In particular, we showed how genetic and linguistic exchanges differed in the past in this area: some cultural exchanges were maintained without genetic exchanges. The methodological framework and the linguistic simulation tool developed here can be used in future work for disentangling complex linguistic and genetic evolutions underlying human biological and cultural histories.

This chapter considers the physical change of the workspace chronologically, geographically, and by industry. From the case studies of pottery, glass, and textile making, as well as food processing, it discusses the standardization of the Roman practice, as seen at Timgad in North Africa, of zoning and conglomerating crafts in early Islam across the Near East and Central Asia. While acknowledging this continuity with the past, it examines the novelty and significance of manufacturing after 800, when ‘post-Roman’ ceased to be a meaningful description of Near Eastern economy, and questions whether urban crafts experienced differentiated or similar forms of development.

AbstractChanging content of detrital input in laminated sediments traced by XRF scanning and microfacies analyses reflect prominent variations in sedimentation processes in the Aral Sea. A high-resolution record of titanium from a core retrieved in the northwestern Large Aral Sea allows a continuous reconstruction of wind strength and frequency in western Central Asia for the past 1500 yr. During AD 450–700, AD 1210–1265, AD 1350–1750 and AD 1800–1975, detrital inputs (bearing titanium) are high, documenting an enhanced early spring atmospheric circulation associated with an increase in intensity of the Siberian High pressure system over Central Asia. In contrast, lower titanium content during AD 1750–1800 and AD 1980–1985 reflects a diminished influence of the Siberian High during early spring with a reduced atmospheric circulation. A moderate circulation characterizes the time period AD 700–1150. Unprecedented weakened atmospheric circulation over western Central Asia are inferred during ca. AD 1180–1210 and AD 1265–1310 with a considerable decrease in dust storm frequency, sedimentation rates, lamination thickness and detrital inputs (screened at 40-μm resolution). Our results are concurrent with changes in the intensity of the Siberian High during the past 1400 yr as reported in the GISP2 Ice Core from Greenland.

In the past two decades historical research and theoretical refinements have provided military historians with new insights into “Chinese imperialism,” late Qing warfare, and ethnic cleansing during the 1850-1877 campaigns in Northwest China, Central Asia, Yunnan, and Guizhou. In particular, Robert Jenks’Insurgency and Social Disorder in Guizhou: The Miao Rebellion, 1854-1873, David Atwill’sThe Chinese Sultanate: Islam, Ethnicity and the Panthay Rebellion in Southwest China, 1856-1873, and Hodong Kim’sHoly War in China: The Muslim Rebellion and State in Chinese Central Asia, 1864-1877have stressed the commonality of Chinese practices with other colonial and imperial states. These authors share a common conclusion that the Qing re-conquest resulted in widespread massacres, ethnic relocations, and subsequent immigration of Han settlers into each region. This historiography examines recent works on the military aspects of the 1850-1877 conflicts in these ethnic and territorial “frontiers” and highlights opportunities for historians to take advantage of new theoretical and archival resources.
