The site of Dmanisi, Georgia, has yielded an impressive sample hominid cranial and postcranial remains, documenting the presence Homo outside Africa around 1.8 million years ago. Here we report on a new cranium from Dmanisi (D4500) that, together with its mandible (D2600), represents world's first completely preserved adult skull early Pleistocene. D4500/D2600 combines small braincase (546 cubic centimeters) large prognathic face exhibits close morphological affinities earliest known fossils...
A common assumption in the evolutionary scenario of first Eurasian hominin populations is that they all had an African origin. This also seems to apply for Early and Middle Pleistocene populations, whose presence Europe has been largely explained by a discontinuous flow emigrant waves. Only recently, some voices have speculated about possibility Asia being center speciation. However, no hard evidence presented support this hypothesis. We present from most complete up-to-date analysis...
Significance The mandibles of the early Pleistocene hominins from Dmanisi, Georgia, exhibit wide morphological variation, but causes diversity remain largely unknown. Here we quantify effects heavy tooth wear and wear-related bone remodeling on mandibular variation. Using modern hunter–gatherer populations as a reference, show that features such dental arcade form, corpus height, symphyseal inclination change substantially with progressive wear. These data indicate Dmanisi reflect normal...
Due to the scarcity of fossil record, in vivo changes dentognathic system early Homo are typically documented at level individual specimens, and it remains difficult draw population-level inferences about dietary habits, diet-related activities lifestyle from patterns alterations. The Plio-Pleistocene hominin sample Dmanisi (Georgia), dated 1.77 million years ago, offers a unique opportunity study individuals belonging single paleodeme Homo.We analyze pathologies sample, comparative samples...
Abstract Objectives There is continuing controversy over the number of taxa documented by Dmanisi hominins. Variation may reflect age and sex differences within a single population. Alternatively, two (or more) distinct species be present. Our null hypothesis states that just one population represented at site. Materials methods We assess likely sources variation in endocranial capacity, craniofacial mandibular morphology, expression characters related to aging dimorphism. use coefficient...
The frontal sinuses are cavities inside the bone located at junction between face and cranial vault close to brain. Despite a long history of study, understanding their origin variation through evolution is limited. This work compares most hominin species' holotypes other key individuals with extant hominids. It provides unique valuable perspective in position, shape, dimensions based on simple reproducible methodology. We also observed covariation size shape underlying lobes species from...
These authors applied modern protein analysis to an ancient molar from a male Homo antecessor dated 772949 thousand years ago (kya) the Sierra de Atapuerca in Burgos, Spain and also dentine enamel erectus 1770 kya. They found that composition of these proteomes is similar humans, including enamel-specific amelogenin, enamelin, ameloblastin, amelotin protease matrix metalloproteinase. Indeed, they had modern-like faces with considerably deep ancestry genus Homo, cranial morphology...
The normal stimulated salivary flow rate averages 1.5–2.0 mL/min while the unstimulated – is approximately 0.3–0.4 mL/min. Below this average, it considered hyposalivation. Hyposalivation may be an accompanying symptom of multiple chronic illnesses. Salivary within Georgian population unknown. This study investigates hyposalivation in and examines if how social conditions, liquid intake, diseases influence We examined 135 individuals (61 men 74 women) different age groups. Questionnaires...
