Since the middle of 1970s, one rock-shelter, six caves and one open archaeological site have yielded several hominid fossils. Among them, fossils from Yonggok, Mandal, Sangsi and Hungsu cave sites are useful to reconstruct the general shape of the Upper Pleistocene Hominids in Korea. The main study of this paper is to focus on the reconstruction of the general shape of the upper Pleistocene hominids, and to examine the cause of cranial changes from the late upper Paleolithic to Mesolithic period in Korea. Biomechanical principles are also applied to reconstruct the social activity of the upper Paleolithic man in Korea. In addition, it is assumed that main proponent of Paleolithic cultures in Korea might be Homo sapiens rather than any other species. Based on the anatomical characteristics of skull, the axillary border of the scapular and the midshaft of the femur, general appearance of Homo sapiens during the Pleistocene in Korea could be reconstructed. 相似文献

The Jungwon region, developed under the calcites deposit, contains 6 caves and 1 rock-shelter where we can find many animal bones. During the middle Pleistocene, some warm animals lived here and the number of species was increased in the course of the upper Pleistocene. In the upper Pleistocene, the young and old deer have been hunted as the main prey and they have been transported into the occupation area of prehistoric people. The cut-marks on the bones and the existence of bone tools reveal us their mode of subsistence. 相似文献

The large mammals of Vallonnet cave, found into a level contemporary of Jaramillo event, are characteristics of the second half of the Lower Pleistocene. Some differences with the faunas of Fuente Nueva 3 and Barranco Leon, in Spain, which datation is the middle of the Lower Pleistocene, show that Vallonnet is younger. On the other hand, the differences are clear with Soleilhac faunas, which datation is the beginning of the middle Pleistocene. 相似文献

This study reports on the skeletal remains of an infant clavicle - specimen ATD6-37 - belonging to the Homo antecessor species, unearthed at Lower Pleistocene level TD6 of the Gran Dolina site (Sierra de Atapuerca). Studied alongside a further adult specimen - ATD6-50 -, they provide us with significant information on two key paleobiological aspects of these early humans: body shape and development. Based on the analytical results, the paper proposes a more accurate proportional method for determining age at death is applied to the fossilized infant clavicle under study. It goes on to hypothesize on postcranial growth and body shape and discusses morphological patterns and age at death of these early humans through comparisons with a wide range of infant dental samples and clavicular specimens in early and modern humans. 相似文献

Fauna associated with stone artifacts have recently been uncovered, in the course of a survey from a cave site named Baerya, town land of Bijie, Guizhou province. The first observations suggest a human occupation. In the absence of chrono-stratigraphic data, it is not possible to assess the age of the site. Nevertheless the presence of lower Pleistocene fauna suggests a very ancient age for this human occupation. Further field research will be necessary to determinate the age and nature of the site. 相似文献

The Late Pleistocene hominin fossil assemblage from Liujiang, South China include a fairly well-preserved cranium, a right os coxa, a complete sacrum, and other postcranial elements all belonging to a single individual. This rare discovery offers us a unique and singular opportunity in understanding this Late Pleistocene hominin's body proportion and relative cranial capacity (encephalization quotient [EQ]), and also pelvic morphology. Using the available right innominate and its mirror-imaged left side, we reconstruct Liujiang hominin's pelvis. Our analysis of the pelvis indicates that the Liujiang hominin has a very gracile and modern-like pelvic morphology. Indeed, all of the pelvic dimensions are smaller than those of other Pleistocene hominins. Moreover, the pelvic characteristics typical of Middle and Late Pleistocene hominins including Neanderthals cannot be identified in the Liujiang pelvis. In contrast, both Liujiang's metric and non-metric features indicate affinities to more recent human populations including our modern Chinese collections from Guangxi of south China. Further support of this assessment comes from the EQ value of 5.754 for Liujiang which is closer to Minatogawa 2 and modern Chinese populations than to Middle and Late Pleistocene fossil hominins. Our analysis of body shape shows that Liujiang has body proportion (i.e. body height relative to body breadth) typical of warm-adapted populations. Based on these findings, we reason that the modern physical characteristics of Liujiang may allude to a more recent geological age. Alternatively, its morphological “modernity” could also point to a much higher degree of skeletal variation within Late Pleistocene hominins in East Asia. 相似文献

The authors of models concerning cooperation found an interesting application point in mutualism and symbiosis. Phenomena which are to be found in symbiosis are integrated by the various models in relation to the 'Prisoner's Dilemma': 'cost-benefit' ratio components, signals, neighbourhood interaction or reciprocity. Reciprocal altruism is found in symbiosis, but others strategies seem more to reflect human societies, where choice is unrestricted. It is very difficult to give a value to cost and benefit equilibriums. The biological environment interferes and a model based on a dominant strategy is often limited or insufficient to report on the living system's evolution. 相似文献
