Modern human behaviour and Pleistocene Sahul in review

Abstract The Middle to Upper Palaeolithic transition in Europe has furnished a ‘package’ of archaeologically visible innovations that are claimed to reflect modern human behaviour. McBrearty and Brooks (2000) documented the gradual assembling of the package over a 200,000 year period in the African Middle Stone Age and proposed that it was later exported to other regions of the Old World. Mellars (2006) recently proposed that modern humans quickly spread from Africa with the package of modern human behaviours and colonised not only Europe but also southern Asia and ultimately Australia. In this paper, we examine the late Pleistocene-early Holocene archaeological record of Sahul to establish if the package was brought here by the earliest colonising groups. We find that the package is not evident at the earliest sites; rather, its components were gradually assembled over a 30,000 year period following initial occupation of the continent by anatomically and behaviourally modern humans. The review further supports the view that there is currently no package of archaeologically visible traits that can be used to establish modern human behaviour, as the components not only appear in different continents at different times, but also at different times and locations within continents such as Australia. This review also identifies chronological and geographical patterning of the individual ‘traits’ and proposes six ‘zones of innovation’ across Sahul.

A progress report on research into stone artefacts of the southern Arcadia Valley, central Queensland

Abstract We report on progress made to date on a collaborative project which aims to shed light on various aspects of lithic technology in the southern Arcadia Valley, central Queensland. Analysis of >4000 stone artefacts indicates that silcrete was an important lithic resource locally. Initial results from portable x-ray fluorescence analysis of a sample of artefacts suggests that this technique may be capable of characterising geochemical signatures for different silcrete sources. Gloss analysis suggests that 20–45% of the silcrete artefacts were heated prior to manufacture. Further use of this method, in combination with archaeomagnetism, is expected to provide more precise information about this practice.
