支持文物在澳大利亚的引入、扩散和衰落的时机一直备受争议。在澳大利亚东南部，在至少8500年前首次出现后，支持文物的数量在4000年至3500年前大幅增加，以至于在许多遗址中都能找到它们，并从那时起在个别遗址中大量记录。从大约1500年前开始，它们的数量明显减少，到英国殖民时似乎已经消失了。解释其扩散的模型提出了这样的命题，即增加的人工制品产量是由气候变化带来的觅食风险和/或社会重组引发的，气候变化到一个比全新世任何时候都更凉爽和干燥的地区，加上加剧的ENSO气候条件。我们的研究通过综合使用磨损和残留物分析，推断悉尼盆地贻贝庇护所使用背衬文物，从而发展了这一假说。这些推论为工具生产和使用因气候条件变化而演变的性质提供了新的见解。皇冠版权所有(C)2009由爱思唯尔有限公司出版。保留所有权利。
The timing of the introduction, proliferation and decline of backed artefacts in Australia has been much debated. In south-eastern Australia, after initially appearing at least 8500 years ago, backed artefacts greatly increased in number between 4000 and 3500 years ago to the extent that they are found in numerous sites and are recorded in large numbers in individual sites from that time. From about 1500 years ago they declined markedly in number and had seemingly disappeared by the time of British colonization. Models explaining their proliferation advance the proposition that increased backed artefact production was triggered by heightened foraging risk and/or social re-organisation brought about by a change in climate to a regime which was cooler and drier than any other time during the Holocene combined with intensified ENSO climatic conditions. Our study develops this hypothesis by inferring the use of backed artefacts at Mussel Shelter in the Sydney Basin through an integrated use-wear and residue analysis. These inferences provide new insights into the nature of the evolutionary changes in tool production and use in response to the period of altered climatic conditions.
