The `human revolution' in lowland tropical Southeast Asia: the antiquity and behavior of anatomically modern humans at Niah Cave (Sarawak, Borneo), , Barker G, Barton H, Bird M, Daly P, Datan I, Dykes A, Farr L, Gilbertson D, Harrisson B, Hunt C,
Recent research in Europe, Africa, and Southeast Asia suggests that we can no longer assume a direct and exclusive link between anatomically modern humans and behavioral modernity (the `human revolution'), and assume that the presence of either one implies the presence of the other: discussions of the emergence of cultural complexity have to proceed with greater scrutiny of the evidence on a site-by-site basis to establish secure associations between the archaeology present there and the hominins who created it. This paper presents one such case study: Niah Cave in Sarawak on the island of Borneo, famous for the discovery in 1958 in the West Mouth of the Great Cave of a modern human skull, the `Deep Skull,' controversially associated with radiocarbon dates of ca. 40,000 years before the present. A new chronostratigraphy has been developed through a re-investigation of the lithostratigraphy left by the earlier excavations, AMS-dating using three different comparative pre-treatments including ABOX of charcoal, and U-series using the Diffusion-Absorption model applied to fragments of bones from the Deep Skull itself. Stratigraphic reasons for earlier uncertainties about the antiquity of the skull are examined, and it is shown not to be an `intrusive' artifact. It was probably excavated from fluvial-pond-desiccation deposits that accumulated episodically in a shallow basin immediately behind the cave entrance lip, in a climate that ranged from times of comparative aridity with complete desiccation, to episodes of greater surface wetness, changes attributed to regional climatic fluctuations. Vegetation outside the cave varied significantly over time, including wet lowland forest, montane forest, savannah, and grassland. The new dates and the lithostratigraphy relate the Deep Skull to evidence of episodes of human activity that range in date from ca. 46,000 to ca. 34,000 years ago. Initial investigations of sediment scorching, pollen, palynomorphs, phytoliths, plant macrofossils, and starch grains recovered from existing exposures, and of vertebrates from the current and the earlier excavations, suggest that human foraging during these times was marked by habitat-tailored hunting technologies, the collection and processing of toxic plants for consumption, and, perhaps, the use of fire at some forest-edges. The Niah evidence demonstrates the sophisticated nature of the subsistence behavior developed by modern humans to exploit the tropical environments that they encountered in Southeast Asia, including rainforest

Uranium series dates from Qesem Cave, Israel, and the end of the Lower Palaeolithic, 2003, Barkai, R. , Gopher, A. , Lauritzen, S. E. , And Frumkin, A.
Israel is part of a geographical ?out of Africa? corridor for human dispersals. An important event in these dispersals was the possible arrival of anatomically modern humans in the Levant during the late Middle Pleistocene1,2,3. In the Levant the Lower Paleolithic ends with the Acheulo-Yabrudian complex, characterized by striking technological developments4,5 including the introduction of advanced technological innovations such as systematic blade production and the disappearance of hand-axes . These reflect new human perceptions and capabilities in lithic technology and tool function, as well as innovative human adaptation6. Qesem Cave, discovered in 2000, has a rich, well-preserved Acheulo-Yabrudian sequence holding great promise for providing new insights into the period. Here we report the dates of this cave obtained by U-series of speleothems and their implications. The results shed light on the temporal range of the Acheulo-Yabrudian and the end of the Lower Paleolithic, suggesting a long and unique cultural phase between the Lower Paleolithic Acheulian and the Middle Paleolithic Mousterian, starting well before 350 kyr and ending at ca. 200 kyr.

Stratigraphic and technological evidence from the middle palaeolithic-Chtelperronian-Aurignacian record at the Bordes-Fitte rockshelter (Roches dAbilly site, Central France) , 2012, Aubry Thierry, Dimuccio Luca A. , Almeida Miguel, Buylaert Janpieter, Fontana Laure, Higham Thomas, Liard Morgane, Murray Andrew S. , Neves Maria Joo, Peyrouse Jeanbaptiste, Walter Bertrand

This paper presents a geoarchaeological study of Middle and Upper Palaeolithic (Châtelperronian, Aurignacian and Solutrean) occupations preserved at the Bordes-Fitte rockshelter in Central France. The lithostratigraphic sequence is composed of near-surface sedimentary facies with vertical and lateral variations, in a context dominated by run-off and gravitational sedimentary processes. Field description and micromorphological analysis permit us to reconstruct several episodes of sediment slope-wash and endokarst dynamics, with hiatuses and erosional phases. The archaeostratigraphic succession includes Châtelperronian artefacts, inter-stratified between Middle Palaeolithic and Aurignacian occupations. Systematic refitting and spatial analysis reveal that the Châtelperronian point production and flake blanks retouched into denticulates, all recovered in the same stratigraphic unit, result from distinct and successive occupations and are not a ‘transitional’ Middle to Upper Palaeolithic assemblage. The ages obtained by 14C place the Châtelperronian occupation in the 41–48 ka cal BP (calibrated thousands of years before present) interval and are consistent with the quartz optically stimulated luminescence age of 39 ± 2 ka and feldspar infra-red stimulated luminescence age of 45 ± 2 ka of the sediments. The Bordes-Fitte rockshelter sequence represents an important contribution to the debate about the characterization and timing of the Châtelperronian, as well as its affinities to earlier and later industries.
