Until now, the oldest known human hair was from a 9000-year-old South American mummy. Here we report fossil hairs of probable human origin that exceed that age by about 200,000 years. The hairs have been discovered in a brown hyaena (Parahyaena brunnea) coprolite from Gladysvale cave in South Africa. The coprolite is part of a hyaena latrine preserved in calcified cave sediment dated between 195,000 and 257,000 years ago. This find supports the hypothesis that hyaenas accumulated some of the early hominin remains found in cave sites, and provides a new source of information on Pleistocene mammals in the Sterkfontein Valley.  相似文献

This paper seeks to make a contribution to current debates concerning the dislocation in landscape research between experiential approaches and quantitative techniques of landscape analysis. It focuses upon a group of archaeological sites that are caught in the centre of this divide: plough-levelled sites recorded as cropmarks on aerial photographs. The application of experiential landscape analysis to plough-levelled sites is explored, along with the value of incorporating information derived from the study of the aerial photograph. It is contended that richer, more rounded, interpretations of landscape are possible when combining aspects of quantitative and qualitative landscape research.  相似文献

A microfluidic device has been developed for the sex identification of ancient DNA samples and works by manipulating liquids within an environment of micrometer dimensions. In this work a range of microfluidic DNA extraction methods were evaluated for their compatibility with ancient DNA samples, and the use of streptavidin-coated super paramagnetic particles to isolate biotin-labeled abasic sites within damaged DNA was shown to be the most reproducible. Polymerase chain reaction-based DNA amplification was possible on the microfluidic device when less than 50 pg of template DNA was added. As a proof-of-principle, powdered bone samples were analysed using the integrated methodology developed. Following conventional capillary gel electrophoresis, two out of the three samples produced positive amplification results and were successfully identified as female. These sex identifications were corroborated by independent Amelogenin, anthropological and Y chromosome analysis. The work reported here is the first step in the development of a complete miniaturized microfluidic system that would enable on-site ancient DNA analysis.  相似文献

Abstract

Despite the crucial position he occupies in Irish history as one of the leaders of the Easter Rising, and the political – and emotional – impact of his subsequent execution, while wounded, by the British Army on 12 May 1916, the writings of Edinburgh-born James Connolly have often been overlooked in both Irish and Scottish studies, and not just in accounts of the Rising but also in the wider context of cultural connections, including cultures of commemoration. In particular, Connolly’s surviving literary work, including Under Which Flag?, the drama staged on the eve of Easter 1916, as well as poems and songs, has had limited attention. This article reconsiders Under Which Flag? in comparison with Yeats and Gregory’s Cathleen ni Houlihan in order to demonstrate the central place the drama holds as a continuation – and complication – of Connolly’s political and journalistic writings. If Connolly is a neglected figure as a writer – as opposed to a political leader and martyr – then the play he left behind (once thought to have been lost, like another of his dramas, The Agitator’s Wife) affords us an opportunity to reassess his contribution to the struggle for independence as part of its literary wing.  相似文献

Macroscopic examination, histomorphometry and Fourier Transform Infrared Spectroscopy (FTIR) are applied to the analysis of burned bones from the early Anglo-Saxon cemetery at Elsham in Lincolnshire, UK. These methods were undertaken to gain a greater understanding of pyre conditions from an archaeological context and the effects of burning on bone microstructure. Sixteen samples were employed for thin-section analysis while eight samples were used with FTIR. The results suggest that these methods correspond well with macroscopic examination, though anomalies did occur. The techniques employed in this paper have demonstrated that the temperatures reached on the funerary pyres at Elsham ranged from 600 °C to over 900 °C under oxidizing conditions.  相似文献
