<p>El objetivo de este trabajo es evaluar la pertinencia de la métrica dental para obtener información sexual en individuos que habitaron el curso inferior del río Colorado durante el Holoceno tardío (ca. 3000-250 años AP), discutir el grado de dimorfismo sexual e identificar las variables cuantitativas de la dentición que permitan discriminar el sexo de nuevos individuos que se incluyan en futuros análisis. Se estudiaron las medidas máximas bucolinguales y mesiodistales del cuello de los dientes correspondientes a 26 individuos adultos. Las variables más dimórficas corresponden al diámetro bucolingual del canino superior y de ambos segundos molares; en estos casos, las diferencias entre los sexos son estadísticamente significativas. Los resultados obtenidos sobre el dimorfismo sexual se ubican en el extremo superior de los valores correspondientes a diferentes poblaciones humanas. Varios individuos que no contaban con información sexual a través de los métodos tradicionales pudieron ser clasificados desde la métrica dental, lo cual da cuenta del importante potencial de las medidas dentales para contribuir a las caracterizaciones paleodemográficas de conjuntos bioarqueológicos, especialmente en contextos perturbados y con escasa integridad esqueletal.</p><p>Palabras clave: métrica dental; determinación sexual; cazadores-recolectores; curso inferior del río Colorado; Holoceno tardío.</p><p>Abstract<br />The aim of this paper is to evaluate the relevance of dental metrics for obtaining sexual information in individuals who inhabited the lower basin of the Colorado River during the Late Holocene (ca. 3000-250 years BP), to discuss the degree of sexual dimorphism and to identify those quantitative variables adequate for sexual determination of new individuals to be included in future studies. The buccolingual and mesiodistal maximum neck diameters of 26 individual adults were studied. The most dimorphic variables correspond to the buccolingual diameter of the upper canine and both second molars; in these cases, sex differences are statistically significant. The results obtained about sexual dimorphism are located at the upper end of the range for different human populations. Several individuals who had no previous sexual information could be classified using these measurements, which accounts for the significant potential of dental metrics in palaeodemographic characterizations, especially in disturbed bioarchaeological samples.</p><p>Keywords: dental metrics; sexual determination; hunter-gatherers; lower basin of the Colorado River; Late Holocene.</p>

This chapter provides an overview of the geography, hydrology, and climate of NE Africa, with particular reference to the complex interactions between river regime, climate, the biota, and human settlement. During the Early (11.7–8.2 ka) and Middle Holocene (8.2–4.2 ka) the climate was far less arid than today across the Nile basin, including Nubia, albeit with sporadic dry phases. Climatic desiccation set in during the Late Holocene (4.2 ka to present), with minor wet phases. Intervals when the Nile flow regime was apparently shifting from high to low flow and flood plain incision have provisional ages of ca. 8.15–7.75 ka, 6.4–6.15 ka, 5.7–5.45 ka, 4.7–4.25 ka, 3.35–2.9 ka, 2.8–2.55 ka, and 1600 ce. In the Kerma area of Nubia there were two periods of relatively dense human occupation in the earlier part of the Holocene from 10 ka to 8 ka and from 7 ka to 6 ka, with two significant gaps in the archaeological record at 7.5–7.1 ka and 6.0–5.4 ka, that coincided with very low levels in Lake Challa, a maar lake on the eastern flank of Mt Kilimanjaro, near the Ugandan headwaters of the White Nile.

Lake Cahuilla

AbstractFreshwater lakes existed intermittently in the Salton Trough of southern California during the late Holocene. The lakes formed north of the subaerial Colorado River Delta whenever the Colorado River flowed west into the trough instead of south to the Gulf of California. Water filled the trough to a maximum altitude of 12 m. Stratigraphy, radiocarbon dates, and supplementary evidence document four lacustral intervals of Lake Cahuilla between A.D. 700 and 1580. Archaeological sites are associated with the 12-m shoreline and their occupation correlates with these lacustral intervals.

Este trabajo presenta una revisión de la evidencia arqueológica en el cinturón forestal de África Central desde el Pleistoceno Final al Holoceno reciente. El avance generado por la investigación en África en las últimas décadas ha mostrado una mayor complejidad y variabilidad en el patrón de cambio tecnológico de lo que en un principio se estableció. Estos patrones además, difieren en gran medida de los observados en el registro europeo.This paper explores from the Late Pleistocene to the Late Holocene archaeological record of Central África. The advance provided in África by the research during the last decades has shown a more complexity and variabllity in the technological chango pattern than earlier believed. These patterns are quite different from the European record.

Human Relationship

The dingo, or native dog, arrived in Australia with people traveling on watercraft in the Late Holocene. By the time Europeans colonized the continent, dingoes were incorporated into the lives of Indigenous Australians, integrated into their kin systems and songlines, and used for a variety of purposes, including as companion animals, as guards, and as a biotechnology for hunting. Women, in particular, formed close bonds with dingoes, and they were widely used in women’s hunting. The incorporation of dingoes into Indigenous societies would therefore have had a significant impact on people’s lives. The greater contribution of meat to the diet would have allowed increased sedentism, improved fecundity, and therefore population growth. Such changes are hinted at in the archaeological record and indicate that more analysis of subsistence evidence could identify when and how the dingo–human relationship formed and how it varied in different environments across Australia.

Human Subsistence

Land snail shell is a material commonly identified in the Late Holocene archaeological record of eastern Africa. Typically, archaeologists designate land snail shell as a natural occurrence or as debris produced from human subsistence. Ethnographic observations in lowland northeastern Tanzania show that contemporary communities employ the soft parts and shells of land snails, particularly Achatina fulica, for a range of everyday and special purposes. The array of land snail uses by mixed subsistence farmers and agropastoralists in the area documents the significance of A. fulica and other robust land snail species. Present uses of land snails observed in Tanzania offer a set of analogies that, when critically applied, can enrich archaeologists’ interpretations of land snail debris in antiquity.

Initial Results

Since 1993 archaeological surveys and excavations have been undertaken on the southern Curtis Coast as the coastal component of the Gooreng Gooreng Cultural Heritage Project. This paper briefly outlines the physical environment of the study region including geology, vegetation and fauna communities before presenting the preliminary results of archaeological surveys and excavations. These initial results suggest that the region has an extensive mid-to-late Holocene archaeological record that has the potential to contribute to understandings of changes in late Holocene Aboriginal societies in Central Queensland.
