Ecology and affective behavior: Selected results from a quantitative study among Efe foragers of northeast Zaire
Authors: De Zalduondo Barbara O. 
Published: August 2005

AbstractThis paper reports selected results of a quantitative study of the affective behaviour of the Efe, exchange‐dependent hunter‐gatherers of the Ituri forest in northeastern Zaire. Measures of the amount and kind of affective display were based on systematic, direct observation of the routine behavior of three Efe bands in residential settings (camps), using a new technique to characterize affect‐laden behavior according to nonlinguistic information conveyed in the voice. Resulting data provide a direct measure of the affective milieu of a foraging people, providing an objective indicator of the subjective impact of social and ecological conditions, which are thought to affect quality of life. In this paper, measures of “camp mood” are used to explore the psychosocial impact of a 3‐month period of acute food shortage that occurred in the Ituri Project study area in 1983. Contrary to expectation, rates of behaviors conveying pleasure did not exhibit significant change, whereas a 44% increase in expressions of displeasure and a 17% drop in use of complaint tones were observed during the period of hunger. This and other findings support the view that systematic, direct observation in natural habitats can increase our understanding, both of the functions of affective behavior, and of the affective dimension of quality of life.
Prehistoric “fish‐eaters” along the eastern Arabian coasts: Dental variation, morphology, and oral health in the Ra's al‐Hamra community (Qurum, Sultanate of Oman, 5th–4th millennia BC)
Authors: Macchiarelli Roberto 
Published: August 2005

AbstractThe Ra's al‐Hamra prehistoric fishermen lived in isolation on the Qurum rocky promontorium in Oman during the 5th–4th millennia BC. To date, they represent the most ancient and numerous human fossil group excavated from the Arabian peninsula. Like other contemporaneous archaeologically documented small communities along the desert Arabian coasts, they intensively exploited ocean resources and collected molluscs from nearby mangrove swamps. The present study analyzes aspects of dental anthropology (including crown variation, morphology, dental wear, and oral health), in 600 permanent teeth from 49 individuals of both sexes excavated at the Mesolithic RH5‐site by the Italian Archaeological Mission in Oman from 1981 to 1985. In association with a general low degree of morphometric variation, the Ra's al‐Hamra dental crowns show low sexual dimorphism and are consistently reduced in size. These features are unexpected in a preagricultural population, especially when these data are compared to other eastern African and near Middle Eastern prehistoric populations. These data are discussed within the general context of human dental structural reduction occurring during the post‐Pleistocene and are interpreted according to the “increasing population density effect” model. There are other significant differences that characterize the Ra's al‐Hamra dentitions with respect to both eastern and western prehistoric human groups. The frequency of numerous nonmetric crown traits supports the hypothesis that a microdifferentiation phenomenon occurred in this marginal area. The preliminary skeletal analysis and the palaeodemographic profile show that the Omani prehistoric fishermen were affected by genetic isolation and inbreeding as well as strong environmental stress. Because of the grit assimilated with dried fish and the high shellfish consumption, dental wear was extreme in all age groups at Ra's al‐Hamra and occasionally was responsible for serious hematogenously spread infections. In spite of the great anthropological importance of ancient Arabian populations, very few studies on skeletal and dental samples have been completed. The present paper offers an odontological data set for future comparative research in the area.
On the differences between two pelvises of Mousterian context from the Qafzeh and Kebara caves, Israel
Authors: Rak Yoel 
Published: August 2005

AbstractTwo pelvises from a similar archaeological context have been discovered in recent years in two different caves in Israel. The pelvis from the Qafzeh cave (Qafzeh 9) was dated by means of thermoluminescence at approximately 95 kyr BP. All available measurement values, the most significant being those of the diagnostic obturator region, fall within those of the modern range. The other pelvis emanates from the Kebara cave and differs fundamentally from modern pelvises and from the Qafzeh specimen, although the Kebara pelvis is 30,000 years younger than the latter. As in other remains of Neandertal pelvises, the superior public ramus of the Kebara hominid is extremely long and slender and exhibits a cross section unlike that of modern humans. The absolute height of the obturator region is very small. It is these measurements and proportions that set the Kebara pelvis apart from both modern pelvises and the specimen from Qafzeh. The morphological differences and the chronological relationship between the two fossil pelvises support the concept of two distinct evolutionary lineages for these hominids.
Longevity factor in hominoid social organization
Authors: Stephens M. E. 
Published: August 2005

AbstractIn most primate groups emigration of the maturing young of one or the other sex tends to serve as an incest avoidance mechanism. Among most primate species it is the males who change groups. This supports the theory that, in terms of reproductive success, males should compete for mates and females should compete for resources. In hominoids the combination of increased longevity and greater female discrimination in mate selection seems responsible for female emigration. This may relate to the high frequency of patrilocality and male control of resources among human groups.
Diversity of palmar pattern ridge counts in Iranian populations
Authors: Sharif Kamali M. , Mavalwala Jamshed 
Published: August 2005

AbstractWe analyzed bilateral palmar prints of 3,158 individuals from 13 Iranian populations of diverse origins for palmar pattern ridge counts. Right palms did not show greater counts than the left in the majority of the populations studied. Highly significant interpopulational variation was observed for most palmar areas of both males and females. Dendrograms of males and combined sexes showed a good fit with the ethnohistoric background of the populations studied. The results thus demonstrate variation in the palmar pattern ridge counts of populations of diverse origins and may be used as a good measure of population distance.
Skeletal and dental pathology of free‐ranging mountain gorillas
Authors: Lovell Nancy C. 
Published: August 2005

AbstractThe mountain gorillas of the central Virungas have been the subject of field study for the last 30 years; however, our understanding of morbidity and mortality in these apes is limited. This paper describes pathological conditions of the skeleton and dentition of these animals and evaluates lesions in relation to behavioral and environmental data. The skeletal remains of 31 mountain gorillas from the Karisoke Research Center were examined for enamel wear, carious lesions, abscesses, periodontal disease, antemortem tooth loss, trauma, inflammation, arthritis, neoplasia, and developmental anomalies. Two infants, three juveniles, 13 adult males, and 13 adult females form the sample.Enamel wear in the permanent posterior dentition is moderate. Six periapical abscesses were seen; three are associated with antemortem tooth breakage. No carious lesions were observed. Pronounced calculus buildup and alveolar resorption are the most notable pathological conditions of the dentition and affect all adult animals.The primary affliction of the skeleton is arthritis, which affects 14 animals. Vertebral degenerative disease predominates, but there is also temporomandibular joint involvement. Fractures occur at seven locations in the postcranium. In addition, there are five cranial injuries, including a fractured sagittal crest, and a penetrating wound to the vault, which is believed to result from a bite. Also thought to result from a bite is a case of cranial osteomyelitis. The only other inflammatory responses are two cases of idiopathic periostitis and one idiopathic lytic lesion. Button osteomas affect two animals and are the only neoplastic conditions observed. Two animals are afflicted by developmental abnormalities: one animal by idiopathic vertebral fusion and the other by spinal scoliosis.
Effects of size on vervet (Cercopithecus aethiops) gait parameters: A longitudinal approach
Authors: Vilensky Joel A. , Gankiewicz Eva , Townsend Douglas W. 
Published: August 2005

AbstractChanges in the values of certain locomotor parameters were analyzed over a range of speeds for five immature vervet monkeys sampled at 6 month intervals over approximately a 3 year period. Lateral and diagonal sequence walking gaits and transverse and rotary gallops were commonly used. The monkeys switched from walking to galloping at long cycle durations for their mass, although, as a group, their transition speeds were in agreement with data from other mammals. However, for individual monkeys, transition speed was not consistently dependent on body mass. Cycle and stance durations generally increased with increasing size at each speed for each animal, with the greatest increases occurring at slower speeds. Swing durations increased slightly with size. For any particular individual, speed ws highly predictable from cycle (or stance) duration and body mass (or age). However, the multiple regression equations for each animal were significantly different from each other suggesting that no single equation is satisfactory for all of the individuals within a species.
Homologies of the stapedial artery in humans, with a reconstruction of the primitive stapedial artery configuration of euprimates
Authors: Diamond Michael K. 
Published: August 2005

AbstractData drawn from the perspectives of paleontology, comparative anatomy, embryology, teratology, and normal adult variation were analyzed with nine homology criteria in order to determine the homologues of the stapedial artery in adult humans. It was determined that 1) the stem of the stapedial artery does not persist within the cranial cavity; 2) the stem of the ramus inferior is retained in its entirety and forms the upper portion of the stem of the middle meningeal artery; 3) the proximal part of the ramus infraorbitalis is normally absent and is replaced by a collateral shunt arising from the ramus mandibularis; 4) the ramus mandibularis is retained and forms the lower portion of the middle meningeal stem and the inferior alveolar artery; 5) the most proximal portion of the maxillary artery is formed by an anastomotic shunt connecting the external carotid artery to the ramus mandibularis; 6) the anterior division of the ramus superior is normally present and well developed; 7) the posterior division of the ramus superior is present in many individuals; and 8) the junction of the two divisions of the ramus superior with the ramus inferior usually migrates to the floor of the middle cranial fossa. The range of human arterial patterns, and those of all other euprimates, can be derived from a hypothetical primitive pattern that is very similar to that of primitive rodents. In this pattern, the stapedial artery stem enters the middle cranial fossa and trifurcates into the anterior and posterior divisions of the ramus superior and the ramus inferior. In their evolution, strepsirhines initially lose the ramus inferior and haplorhines initially reduce the stapedial artery stem.
Hypothenar radial arch in man: Observations on its distribution, morphology, symmetry, and inheritance
Authors: Karev George B. 
Published: August 2005

AbstractHypothenar radial arch was found in 2.07% of the males and 2.82% of females in a sample of 2,130 Bulgarians. Persons bearing the pattern on the right hand display the highest frequency, followed by those bearing the pattern bilaterally and those with it on the left hand. A well‐expressed tendency of the hypothenar radial arch towards symmetrical occurrence was disclosed through the ratio between the actual and expected frequency of its bilateral occurrence. This ratio is recommended as an efficient estimator of tendency toward symmetry.The presence of the pattern is associated with morphological peculiarities of the other dermatoglyphic features of the palm. Line A ends at two parts of the palm periphery which are extremes of its usual distribution. Line D is shortened and the ridges run more vertically than in palms without the pattern.The connection of the hypothenar radial arch with the border ulnar triradius, along with the observations on the opposite hypothenars in the unilateral cases, provides a support of Wilder's conception concerning the mode of formation of the pattern.A genealogical tree exhibiting transmission of the pattern over three consecutive generations is presented. A pattern of dominant inheritance with a fairly reduced penetrance is compatible with the genealogical data.
The popliteal sesamoid bone (cyamella) in primates
Authors: Le Minor J. M. 
Published: August 2005

AbstractA study of 246 adult nonhuman primates belonging to 34 genera indicates that a popliteal sesamoid bone is always present in the tendon of the popliteus muscle in Prosimii and Callitrichidae. The bone occurs only variably in Atelidae and Pongo, and is usually absent in Gorilla. The bone is absent, or very rare, in Cebus, Cercopithecidae, Hylobatidae, Pan, and humans. When the bone is present, it articulates with the posterior part of the articular surface of the lateral condyle of the tibia, and lies very close to the head of the fibula, at the angulated part of the popliteal tendon, near the tendomuscular junction. The presence of the popliteal sesamoid bone in primates is a primitive character.
Dental paleopathology and agricultural intensification in South Asia: New evidence from Bronze Age Harappa
Authors: Lukacs John R. 
Published: August 2005

AbstractPatterns of dental disease among Bronze Age people of the Indus Valley Civilization are currently based on early and incomplete reports by non‐specialists. This deficiency precludes accurate diachronic analysis of dental disease and its relationship with increasing agriculturalism in the Indian subcontinent. The objective of this paper is to document prevalence of dental disease at Harappa (2500–2000 B.C.), Punjab Province, Pakistan, comparatively evaluate the Harappan dental pathology profile, and use these data to assess theories regarding the dental health consequences of increasingly intensive agricultural dependence.Pathological conditions of the dentition included in the study are abscesses, ante‐mortem tooth loss (AMTL), calculus, caries, hypoplasia, hypercementosis, pulp chamber exposure, and alveolar resorption. The Harappan dentition exhibits a dental pathology profile typical of a population whose subsistence base is agriculture. Dental caries at Harappa are present in 6.8% (n = 751) of the teeth and 43.6% (n = 39) of the more completely preserved dental specimens. The use of a caries correction factor is recommended to permit an estimate of caries induced AMTL in calculating the caries prevalence. All dental lesions are present at higher rates in this Harappan study sample than were reported in previous investigations, and important differences in prevalence of dental disease occur between the genders. Prevalence of dental disease increases in the greater Indus Valley as subsistence becomes more intensive and as food preparation and storage technology becomes more efficient.
Reduction of maxillary molars in Homo sapiens sapiens: A different perspective
Authors: Macho Gabriele A. , Moggi‐Cecchi Jacopo 
Published: August 2005

AbstractCrown and cusp areas, and buccolingual and mesiodistal diameters of maxillary molars of complete upper tooth rows (30 males, 30 females) were analysed in order to quantify changes in size and shape from the first to the third molar. Uni‐ and multivariate analyses revealed the mesial cusps, in particular the protocone (mesiolingual cusp), to be more stable than the other cusps. Although there is a gradient in size from the first to third molar, shape changes were found to be marked. Overall, the findings are in keeping with the field theory and the hypotheses of environmental constraints on later developing teeth. However, not all of the results could be entirely explained by these concepts. Functional aspects seem to account for the relative stability of the protocone and the buccolingual crown diameter. It appears that this functional complex is relatively stable despite the overall reduction of tooth size, which is probably secondary to processes occurring in the jaws and the cranium. This finding may have implications for studies on tooth reduction between populations of different time periods.
Further evidence for the role of supraspinatus in quadrupedal monkeys
Authors: Larson Susan G. , Stern Jack T. 
Published: August 2005

AbstractDifferences in the degree of projection of the greater tubercle above the level of the humeral head in primate proximal humeri have been associated with differing leverage requirements for supraspinatus during arboreal vs. terrestrial quadrupedal locomotion. Since most workers have assumed that supraspinatus acts as a humeral protractor, interpretations of the variation in greater tubercle height have focused on the need for powerful vs. rapid humeral protraction during the swing phase of quadrupedal locomotion. However, in an EMG study on the activity patterns of supraspinatus in the vervet monkey, Larson and Stern (Am. J. Phys. Anthropol. 79:369–377, 1989) reported that although supraspinatus is active during arm elevations against gravity, it is silent during the swing phase of quadrupedal locomotion, and instead acts as a joint stabilizer during support phase. They suggested that the pattern of activity for supraspinatus observed in the vervet was common for all quadrupedal primates, and that differences in greater tubercle projection could be related to the degree of mobility of the shoulder. In the current study, we present additional EMG data on a baboon and three macaques supporting the suggestions offered by Larson and Stern (1989).
Reliable identification of human albumin in ancient bone using ELISA and monoclonal antibodies

AbstractIn order to help reconstruct ancient dietary, domestic, and ritual behaviour, a method was developed to identify the blood protein albumin in ancient skeletal material. This was an inhibition enzyme‐linked immunosorbent assay (ELISA) using a monoclonal antibody of IgG class against human albumin. With fresh material, the technique gave consistent and specific results and could detect as little as 10 ng of albumin. Extracts of bone from the English Civil War (A.D. 1644), Mediaeval (A.D. 1100–1400), Early Saxon (A.D. 450–600), Roman (A.D. 100–200), Iron Age (ca 400 B.C.) and Bronze Age (2200–1700 B.C. cal.) periods were then tested, samples of fresh human and animal bone being included as positive and negative controls, respectively. Albumin was demonstrated in human bone from all periods; there was no evidence of cross‐reactivity with animal material. Detection seemed to depend largely on amount of sample and chronological age; other factors, such as physical integrity of the specimen and soil characteristics, appeared to be less important. Preliminary studies of other ancient skeletal remains showed that animal species could be readily identified and that albumin was probably still detectable in cremated material. It is concluded that our method provides a tool specific and sensitive enough for the reliable identification of the speciesorigin of small fragments of bone (and possibly of blood stains) and will thus allow insight into past behaviour patterns. ELISA may also be suitable for identifying other molecules (such as HLA and ABO) which would help determine racial affiliation and disease predisposition among ancient populations.
Trends and developments in physical anthropology, 1990–91
Authors: Wienker Curtis W. , Bennett Kenneth A. 
Published: August 2005

AbstractThe 1408 members of the American Association of Physical Anthropologists were surveyed by mail regarding professional background, training deficiencies, opinions regarding areas of future importance to the discipline, and teaching/research specializations. A total of 544 responses (39%) resulted; 71% were from professionals in the United States and 16% were from U.S. students. Survey results are compared to surveys done in 1971 and in 1978, and are broken into three cohorts: pre‐1971 Ph.D.s, 1972–1978 Ph.D.s, and post‐1979 Ph.D.s. Statistics and anatomy continue to be common training deficiencies across cohorts. Molecular/cell biology and writing are new training deficiencies that reflect contemporary concerns and trends in the discipline. Anatomy, genetics, ecology, and paleontology are still considered important to the future of physical anthropology; statistics, computer science, and the biomedical sciences are also thought to be of importance to its future. The most frequent teaching/research specializations are growth and development, evolutionary biology, and population studies. Genetics and primatology appear to be losing popularity; biomedical anthropology, statistics, and ecology appear to be gaining it. The survey results have implications for the future training of graduate students and for employment opportunities in physical anthropology.
Intrasexual competition and canine dimorphism in anthropoid primates
Authors: Plavcan J. Michael , van Schaik Carel P. 
Published: August 2005

AbstractA number of factors, including sexual selection, body weight, body‐weight dimorphism, predation, diet, and phylogenetic inertia have been proposed as influences on the evolution of canine dimorphism in anthropoid primates. Although these factors are not mutually exclusive, opinions vary as to which is the most important. The role of sexual selection has been questioned because mating system, which should reflect its strength, poorly predicts variation in canine dimorphism, particularly among polygynous species. Kay et al. (1988) demonstrate that a more refined estimate of intermale competition explains a large proportion of the variation in canine dimorphism in platyrrhine primates. We expand their analysis, developing a more generalized measure of intermale competition based on the frequency and intensity of male‐male agonism. We examine the relative influences of predation (inferred by substrate use), female body weight, body‐weight dimorphism, diet, and sexual selection on the evolution of anthropoid canine dimorphism. Intermale competition is very strongly associated with canine dimorphism. Predation also has a marked effect on canine dimorphism, in that savanna‐dwelling species consistently show greater canine dimorphism than other species, all other factors being held equal. Body‐weight dimorphism is also strongly associated with canine dimorphism, though apparently through a common selective basis, rather than through allometric effects. Body weight seems to play only a minor, indirect role in the evolution of canine dimorphism. Diet plays no role. Likewise, we find little evidence that phylogenetic inertia is a constraint on the evolution of canine dimorphism.
