Archaeological Excavations

Tana di Badalucco cave is located in Imperia (Liguria, Italy), not far from the French border. This site is scarcely known and it has never been studied accurately, even though different archaeological excavations have returned really important elements, both in the archaeological and the paleoenvironmental aspects. Its stratigraphy ranges from Middle Paleolithic to Metal Ages, thus it has registered important climate and environmental variations specific to the Upper Pleistocene and Holocene. From 2012, the Soprintendenza Archeologia della Liguria, the Museo di Archeologia Ligure, and DiSTAV (University of Genova) have been collaborating in order to finally study this promising and complex stratigraphy, trying to reconstruct the paleoenvironmental context of the region. In this work, we present what we were able to assess thanks to the use of micromorphology, the study of undisturbed thin soil sections. This technique has proven useful in recognizing the alternating of cold and warmer conditions during the Quaternary, as well as in identifying primitive signs of human and animal occupation.

Insight Into

AbstractThe discoid core and the Levallois core are important symbols of the Middle Paleolithic Age in the west of the Old World. The two types of artifacts show not only technical relationships but also differences. The discoid core can be classified into two sub-types, namely the unifacial and the bifacial classes. In China, discoid cores may have appeared in the upper Middle Pleistocene, and prevailed in the lower and middle Upper Pleistocene, which corresponded to the middle Paleolithic Age in Europe and to the Middle Stone Age in Africa. The discovery and study of discoid cores provide significant insight into the culture of the Middle Paleolithic Age in China.

Abstract Palynological investigations on sediment cores from three localities in Rondonia in the southern part of the Amazon Basin, indicate that marked vegetational changes have ocurred there. The series of samples from Katira represents the late Cenozoic, probably Quaternary. The sediments from Capoeira might be partly of Holocene age (and possibly Upper Pleistocene as well). Apparently the climatic changes during several intervals of the Late Cenozoic (Quaternary) caused the development of savannas in this region which is now covered in tropical forest.

Upper Pleistocene

Fossil shells collected during excavations at the extinct Janaúba lake in Minas Gerais, were identified on morphological grounds as Biomphalaria aff. glabrata. Since they were found in a stratigraphic horizon associated with bones of Eremotherium laurillardi (Lund), they can be assumed to belong to the Upper Pleistocene. B. glabrata is presently known to occur on a wide area surrounding the microregion of the "Janaúba lake" but not at the place of the "lake" itself and some kilometers around. The present discontinous distribution can be explained by the Pleistocene-Holocene climatic changes which have occurred in the region.

Taphonomic Analysis

Birds are abundant in fossil assemblages of Quaternary sites; they can be used in landscape recon­struction as they are well adapted to the environment. Here we present the analysis of the avian assemblage from the Middle Paleolithic levels of the Llonin Cave, where 558 bird remains have been recovered from levels G-VI and CP-VIII, belonging to at least ten different taxa: Aves indet., Galliformes indet., Lagopus lagopus Linnaeus, 1758, Tetrastes bonasia Linnaeus, 1758, Columba livia/oenas Gmelin, 1789/Linnaeus, 1758, Passeriformes indet., Alaudidae indet., Motacilla sp., Turdus sp., Corvidae indet., Garrulus glandarius Linnaeus, 1758, Pyrrhocorax sp., Pyrrhocorax pyrrhocorax Linnaeus, 1758, Pyrrhocorax graculus Linnaeus, 1766 and Corvus corax Linnaeus, 1758. This assemblage is similar to other assemblages from the Upper Pleistocene of the north of the Iberian Peninsula, and it reflects a mixed landscape, with open areas and woodland. The taphonomic analysis points to a mixed origin of the accumulation, mainly formed by medium-sized corvids dying in the cave, and also raptors accumulating their prey.

AbstractTianhuadong is a cave site located in the northwest of Yunnan Province, China. Since 2010, several surveys and one test excavation have yielded more than 1000 stone artifacts. The lithic assemblage shows some features of Levallois and Quina technologies, similar to those found in Middle Paleolithic sites in the Western Hemisphere. In this study, we summarize the lithic industry and propose a reliable chronology for the site using optically stimulated luminescence (OSL) dating of individual quartz grains extracted from sediments. We applied the standardized growth curve method to deal with the problem associated with the saturation in natural OSL signals in quartz. Our dating results yielded ages of 90–40 ka, suggesting that the associated lithic assemblage could be assigned to Marine Oxygen Isotope Stages 5 and 4 and could potentially represent Middle Paleolithic technologies. Because the number of Middle Paleolithic sites in southwest China is small, this site provides one of the few traces of human occupation in southwest China during the early upper Pleistocene. Thus, it is important for understanding hominin evolution and dispersal in this region.

The paper employs the method of refitting to reconstruct the lithic reduction technologies that were used by the Middle Paleolithic and Initial Upper Paleolithic inhabitants of the site of Kara-Bom (Altai Mountains). It is shown that the Middle Paleolithic technology was oriented at the production of points that were mainly struck from convergent single platform (unidirectional) Levallois cores. The Initial Upper Paleolithic industry is characterized by sub-prismatic opposed platform (bidirectional) cores aimed at the production of blades. The author draws many analogies with synchronous industries distributed from the Levant to the east of South Siberia and Central Asia. The available archaeological, chronological and paleogeographic evidence gives grounds to argue that the development of the Paleolithic culture in Northern Asia was strongly affected by climatic fluctuations that took place during the Upper Pleistocene and had a significant impact on human migration routes.

Heritability Estimates

It is proposed to simplify the debate about the heritability of mental traits in humans by concentrating on two crucial issues: Population specificity of heritability estimates and the relation of these estimates to the malleability of the trait to which they refer. It is demonstrated that due to vast differences between the environmental variations of populations there would have to be a heritability estimate for every imaginable population, and that a heritability estimate allows no predictions whatsoever about the malleability of the trait in question. It is therefore concluded that this field of research should be abandoned.
