Rethinking Wear Rate Analysis: A New Dentin Exposure Proxy and its Applications to Ancient Chinese Populations
Assessing age through dentin exposure often leads to underestimated age due to assumptions of constant molar wear rate. New methods for age-related dentin exposure accrual could facilitate cross-population comparisons independent of dietary habits and sociocultural strategies. We analyzed 3D dentin exposure surfaces in four Chinese archaeological samples to reveal variations in dentin exposure rates linked to socioeconomic practices. Linear regre…
Evaluating a dentin exposure proxy for wear rates estimations on mesolithic and neolithic populations from the near East and the Iberian Peninsula: A comparative analysis
Exploring the interplay of bone lesions: Unraveling health implications and daily life challenges in an Iron Age skeleton from Ya'amun, Jordan
This study analyzed the paleopathological conditions of a 30-year-old male unearthed at the site of Ya'amun in northern Jordan. The skeleton was dated back to Iron age. The paleopathological examinations were performed using macroscopic and radiological analyses. The results revealed multiple significant bone lesions, including periosteal osteosarcoma of the right femur, plagiocephaly, asymmetry of the sacrum, vertebral fractures, anemia, and ost…

Three-Dimensional Proxies to Dental Wear Characterization in a Known Age-at-Death Skeletal Collection
Buccal dental-microwear and feeding ecology of Early Pleistocene Theropithecus oswaldi from Cueva Victoria (Spain)
Age‐related tooth wear in African rainforest hunter‐gatherers
OBJECTIVES: Central African small-scale foragers subsist primarily on hunting game activities and wild plant-food gathering. Starch-rich tubers are underground storage organs (USOs) and staple food resources in savanna and tropical rainforests. However, little is known about the effect of USO consumption on tooth wear development in living hunter-gatherers. We report age- and sex-dependent tooth wear rates in forest-dwelling Baka Pygmies with wel…
Buccal dental microwear as an indicator of dietary habits and dietary adaptation of the Byzantine people of Jordan
This study examined buccal microwear from the Byzantine sites of Yajuz and Sa'ad in Jordan (n = 15) to assess different subsistence economies. An Indian Hindu sample (n = 7) was used for comparative purposes. The results show no differences in the pattern of buccal dental microwear between the two Byzantine sites, while a difference was noted when these sites were compared to Hindus. It is probable that cultural variation was the cause of buccal …

Structural and molecular study of the supraspinatus muscle of modern humans ( Homo sapiens ) and common chimpanzees ( Pan troglodytes )
OBJECTIVES: To analyze the muscle architecture and the expression pattern of the myosin heavy chain (MyHC) isoforms in the supraspinatus of Pan troglodytes and Homo sapiens in order to identify differences related to their different types of locomotion. MATERIALS AND METHODS: We have analyzed nine supraspinatus muscles of Pan troglodytes and ten of Homo sapiens. For each sample, we have recorded the muscle fascicle length (MFL), the pennation ang…
Dental size variability in Central African Pygmy hunter‐gatherers and Bantu‐speaking farmers
OBJECTIVES: Odontometric studies of African populations show high within-group variation in tooth size. Overall, North Africans exhibit smaller dimensions than groups from eastern and southern sub-Saharan regions, but no previous studies have analyzed the full dental metrics among extant African Pygmy hunter-gatherers and Bantu-speaking farmers. Furthermore, the population variability in tooth crown sizes from equatorial rainforest regions remain…

Buccal dental microwear texture and catarrhine diets
OBJECTIVES: Two-dimensional dental microwear analyses on occlusal and nonocclusal enamel surfaces have been widely applied to reconstruct the feeding behaviors of extant primates and to infer ecological adaptations in fossil hominins. To date, analyses of dental microwear texture, using three-dimensional, Scale-Sensitive Fractal Analysis approaches has only been applied to occlusal surfaces. Here, for the first time, we apply this 3D proxy to buc…

Dental-macrowear and diet of Tigara foragers from Point Hope, northern Alaska
Ethnographic studies indicate that Eskimo foragers are characterized by well-defined sexual division of labor and extensive use of anterior teeth as a tool, resulting in higher degrees of wear. However, little is known about the intra-population variation in molar-macrowear rates and dietary implications. Here, percentages of dentin exposure (PDE) were recorded on first mandibular molars among Tigara foragers from Point Hope (Alaska) and attempt …
First molar size and wear within and among modern hunter-gatherers and agricultural populations
Shape analysis of the proximal humerus in orthograde and semi‐orthograde primates: Correlates of suspensory behavior
"Suspensory locomotion" is an expression that encompasses a series of specialized forms of locomotion that mainly orthograde primates use to achieve below-branch traveling. It implies a number of features in the entire body associated with the use of the forelimb in overhead positions. The glenohumeral joint is one of the main joints involved in effective suspensory locomotion, being subject to a delicate balance between the high degree of mobili…

Morphological affinities of the proximal humerus of Epipliopithecus vindobonensis and Pliopithecus antiquus: Suspensory inferences based on a 3D geometric morphometrics approach
Brief communication: Developmental versus functional three‐dimensional geometric morphometric‐based modularity of the human proximal humerus
The proximal humerus is formed by three secondary ossification centers during the postnatal trajectory of the human infant. The ossification centers later grow into the structures of the articular surface, major tubercle, and minor tubercle. There is a purported functional division between the articular surface and the tubercles, with the articular surface mainly responsible for the range of movement of the shoulder joint, and the tubercles beari…
A Comparison of Qualitative and Quantitative Methodological Approaches to Characterizing the Dorsal Side of the Scapula in Hominoidea and Its Relationship to Locomotion
Brief communication: Morphological effects of captivity: A geometric morphometric analysis of the dorsal side of the scapula in captive‐bred and wild‐caught hominoidea
Many osteological collections from museums and research institutions consist mainly of remains from captive‐bred animals. The restrictions related to the space of their enclosures and the nature of its substrate are likely to affect the locomotor and postural behaviors of captive‐bred animals, which are widely considered uninformative regarding bone morphology and anatomical adaptations of wild animals, especially so in the case of extant great a…

Intraindividual and intragroup variability of buccal tooth striation pattern
Intrapopulational tooth striation variability has been studied in a sample of 99 individuals from the medieval agriculturalist population of La Olmeda (Palencia, Spain). The number, length, and orientation of all observed striations were recorded using a scanning electron microscope and an image analyzer system. Tooth striations were observed at 100 × magnification on the buccal surface of Pm4 and M1 teeth. The results obtained for the adult age …
Brief communication: Short‐ and long‐term in vivo human buccal–dental microwear turnover
Buccal–dental microwear depends on the abrasive content of chewed foodstuffs and can reveal long‐term dietary trends in human populations. However, in vivo experimental analyses of buccal microwear formation processes are scarce. Here, we report the effects of an abrasive diet on microwear rates in two adult volunteers at intervals of 8 days over a period of 1 month and document long‐term turnover over 5 consecutive years in the same subjects und…

Age-related variability in buccal dental-microwear in Middle and Upper Pleistocene human populations
Infants are thought to present a different buccal microwear pattern than adults and these, therefore, are generally analyzed separately. However, El-Zaatari & Hublin [2009] showed that occlusal texture in Neandertal and modern human juvenile populations did not differ from their elders. The microwear patterns of a sample of 193 teeth, corresponding to 61 individuals of Homo heidelbergensis, H. neanderthalensis and anatomically modern humans (AMH)…

Mitochondrial DNA diversity in the Llanos de Moxos: Moxo, Movima and Yuracare Amerindian populations from Bolivia lowlands
The genetic diversity observed in the Beni area is higher than that observed in other American populations living in much larger areas and with a long, known evolutionary history, despite the reduced area of Moxos. This could result from processes of reproductive isolation between groups, followed by population expansions and migration, where genetic drift might have be a major evolutionary force in population differentiation
