Later Stone Age (LSA) hunter–gatherers and herders co-existed in South Africa during the last 2000 years. In spite of being the focus of intensive research over the years, the biological status and origins of the herders are still unclear. Did they represent a genetically distinct immigrant population who remained separate from the indigenous hunter–gatherers, or where they indigenous hunter–gatherers who took up herding after contact with herders, probably in northern Botswana? Here, this issue is investigated using craniometric data collected on a large sample of individually dated human crania from coastal LSA context. Mahalanobis distances (D), calculated from the raw metric data, show that there was a small increase in inter-individual craniofacial variation after the introduction of herding at ca. 2000 BP. Here it is argued that this small increase in variation is neither consistent with a large-scale immigration of genetically distinct herders into South Africa, or the long-term co-existence of two genetically distinct populations. Two alternative explanations fit the data better: (1) herding entered South Africa via the small-scale immigration of genetically distinct herders; and (2) local hunter–gatherer populations adopted herding after coming in contact with herders in northern Botswana. While small-scale immigration would not have had a major influence on the local gene pool, it would have increased variation to some extent as immigrants mixed with local populations. If small-scale external gene flow was not a factor in the introduction of herding, secular issues related to the introduction of herding could explain the increased variation in post-2000 BP populations. 相似文献

In 2013 there was a spike in the illegal export of rosewood, a highly‐valued tropical hardwood, from Belize. Hewn by Maya workers at night, logs were sold to Chinese buyers. Although protected by international conservation agreements, container‐loads of rosewood were exported unprocessed, unmarked and untaxed. This article examines the rosewood exports, providing a critical analysis that seeks its underlying causes and lessons for development. Drawing on extensive archival research, interviews with multiple actors, and data on China's rosewood imports, the authors show that the exports reflect a long‐standing pattern: the extraction and export of unprocessed primary commodities from Belize's forests. However, contemporary patterns are not simply repeating colonial history. On the demand side, the recent rosewood boom was triggered by a rapid rise in demand from urban, middle‐class consumers in China, stimulating a new commodity chain. On the supply side, the ‘rosewood crisis’ was facilitated by a peculiar legal‐political conjuncture: it occurred during a period after the Maya communities had won legal rights to their forests through the courts, but before the state had recognized those rights. Thus the incomplete recognition of indigenous land rights collided with long‐standing patterns of forest extractivism and explosive demand in China. 相似文献
