Porotic hyperostosis: representative of a childhood condition.

Porotic hyperostosis is currently considered to be one of several stress markers available for assessing the health and nutritional status of past human populations. The present study questions one of the basic assumptions underlying its use; that is, that the occurrence of porotic hyperostosis in an individual represents an episode of anemia that was current or had occurred within a relatively short period prior to death. A synthesis of data from a Romano-British site Poundbury Camp, anthropological and clinical studies, and information on bone physiology suggests that lesions of porotic hyperostosis seen in adults are most probably representative of a childhood episode of anemia. Lesions seen in adults are the result of bone changes occurring in the growth period that have not undergone complete remodelling. This viewpoint has implications for future interpretation of data on porotic hyperostosis obtained from skeletal collections.

Variations in form of the hypoglossal canal.

Variation in the nature and extent of division of the hypoglossal canal can be classified by a simple scoring scheme. Applied to three series of crania of differing provenance, the results indicate a continuity in expression of the trait rather than the dichotomous character utilized in previous studies. The similarity in results in these three populations, of widely differing environment, suggests fairly strict canalization of development.

Pathology and the posture of the La Chapelle-aux-Saints Neandertal.

The depiction of the Neandertals as incompletely erect was based primarily on Boule's (1911, 1912a, 1913) analysis of the La Chapelle-aux-Saints 1 partial skeleton. The inaccurate aspects of Boule's postural reconstruction were corrected during the 1950s. However, it has come to be believed, following Straus and Cave (1957), that Boule's errors of reconstruction were due to the diseased condition of the La Chapelle-aux-Saints 1 remains, rather than to Boule's misinterpretation of morphology. The abnormalities on the La Chapelle-aux-Saints 1 postcranium include: lower cervical, upper thoracic, and lower thoracic intervertebral degenerative joint disease (DJD), a distal fracture of a mid-thoracic rib, extensive DJD of the left hip, DJD of the right fifth proximal interphalangeal articulation, bilateral humeral head eburnation, and minor exostosis formation on the right humerus, ulna, and radius. These were associated with extensive alveolar inflammation including apical abscesses and antemortem tooth loss, some temporomandibular DJD, bilateral auditory exostoses, and minimal occipital condyle DJD. None of these abnormalities significantly affected Boule's Neandertal postural reconstruction, and a review of his analysis indicates that early twentieth century interpretations of skeletal morphology (primarily of the cranium, cervical vertebrae, lumbar and sacral vertebrae, proximal femora and tibiae, posterior tarsals, and hallucial tarsometatarsal joint), combined with Boule's evolutionary preconceptions, were responsible for his mistaken view of Neandertal posture.

The dentition of the "old man" of La Chapelle-aux-Saints and inferences concerning Neandertal behavior.

It has been suggested that the fossil Neandertal from La Chapelle-aux-Saints was so toothless that he would have had to have his food pre-chewed or otherwise prepared for him. This has also led to the inference that a high level of altruistic social behavior was characteristic of Neandertals. This appears to be in keeping with a current trend among anthropologists to upgrade the cultural and evolutionary status of Neandertals. Close examination of the recovered teeth and the condition of the alveoli indicates that the "old man" of La Chapelle-aux-Saints had upper and lower incisor, canine and premolar teeth on the left side intact and probably in occlusion, and that the same was true of these teeth in the right maxilla. Mandibular incisors, canine, and first premolar had probably been lost to a tumor or abscessing on the right side, but this pathology may have developed near the time of death. The right mandibular second premolar was probably functional, although tilted similarly to the intact premolar on the left. It is very unlikely that the individual was unable to chew food. The dentition thus gives no reliable evidence of altruistic behavior by his cohorts. This study may also relate to hypotheses concerning the ancestry of anatomically modern humans.

Observations of dental diseases among prehistoric populations of Hungary.

The incidence of dental disease among people in developing countries today raises questions about the variation in the oral health of prehistoric populations. Considering these questions, we offer observations describing several types of dental disease which occurred among certain prehistoric populations of Hungary. The dental remains of 162 individuals recovered from seven sites of the Neolithic, Copper, and Bronze Age periods were examined for evidence of caries, hypoplasia, and periodontal disease. Appropriate methods were used to describe and record these dental lesions. The incidence of dental caries was low by comparison to other prehistoric agriculturists except for two forms of root caries: cervical and cemental. These types accounted for 68% of all the carious teeth recorded. Enamel hypoplasia was also lower than expected, occurring on only 4% of the total number of teeth. Periodontal abscesses were rare but other milder forms of periodontal lesions were frequent. Alveolar bone resorption occurred in varying degrees and followed the expected age distribution. The few exceptions were children or adolescents whose crania had other lesions suggesting a mineral metabolic disturbance. The lower incidence of enamel caries is likely due to high fluoride ingestion which also may have influenced the expression of enamel hypoplasia. No clear population trends were seen in dental disease incidence except for cemental caries which were found among Copper and Bronze Age remains.

Diachronic variation in cranial thickness of Near Eastern populations.

Cephalometric radiographs were taken of 111 skulls of skeletal remains of populations living in Israel and Jordan during the last 12,000 years. From these radiographs, skull length and height, and cranial thickness were measured. For each sex and period, high correlations were found between cranial thickness at vertex, bregma, and lambda. Cranial thickness at nasion was correlated with sinus width but not sinus height. All measurements were correlated with skull length but not skull breadth. Using multivariate analysis, no significant differences in cranial thickness were found between the sexes. Significant diachronic trends were found in lambda and sinus width, and they were independent of variation in skull length.

The eruption pattern of the permanent incisors and first permanent molars in Australopithecus (Paranthropus) robustus.

This study aims to reassess the claim that the eruption sequence of the permanent incisor and first permanent molar teeth of Australopithecus (Paranthropus) robustus is identical with that in modern Homo sapiens. Eight fossil hominid mandibles of equivalent dental developmental age were chosen for comparative study. Emphasis has been placed upon the comparative timing of events within the growth period rather than eruption sequence alone. The results of this study indicate that Homo sapiens and Australopithecus (Paranthropus) robustus share the same pattern of permanent molar and incisor eruption and that this is significantly different from the pattern of eruption shared by the great apes, Australopithecus africanus and Australopithecus afarensis.

Long bone lengths and gestational age distributions of post-contact period Arikara Indian perinatal infant skeletons.

Prenatal growth is adversely affected by poor socioeconomic conditions where disease and chronic undernutrition prevail. Premature and small-for-gestational-age births occur at higher frequency. Post-contact Arikara Indian populations of South Dakota experienced a rapidly changing and disruptive environment that included deterioration of the subsistence base and increased morbidity. This research tests resulting fetal growth effects through comparative analysis of two perinatal infant samples of the early (A.D. 1600-1733) and the late (A.D. 1760-1835) post-contact period. Perinatal infants recovered from late cemeteries include a higher percentage of smaller skeletons, as determined using long bone diaphyseal lengths, than is documented for the earlier time period. This contrast shows that it is possible to detect fetal growth differences in samples of archaeological context.

Analysis of a microcephalic child from the late period (ca. 1100-1700 A.D.) of central California.

Microcephaly is a severe developmental abnormality which is induced either genetically or environmentally. The archaeological evidence for the occurrence of this abnormality is minimal. Out of six possible cases, only three have been published; all are adult and represented solely by cranial remains. The focus of the current study is the nearly complete skeleton of a 3-year-old child recovered during archaeological excavations in San Jose, California. The individual is compared to a sample of 184 California Indians, ranging from 0.5 to 5 years, which were also recovered from archaeological excavations. In order to determine if microcephaly was the only disorder represented, metrical comparisons of the skull and postcrania and gross morphological comparisons of endocranial casts were made. Based on these comparisons the individual was determined to have a cranial vault size comparable to 6-month-old infants (630 cc), a facial skeleton equivalent to the 9-month-old to 2-year-old age groups, and a reduced stature. Due to the mosaic nature of the skull, the observed morphology was interpreted in terms of functional cranial components. Severe malformation of the orbital aspect of the frontal lobes was found in conjunction with a significant reduction in size of the cerebral cortex and left temporal lobe. On the basis of this analysis, the individual was found to exhibit the total morphological pattern associated with microcephaly. A differential diagnosis of other possible genetic disorders is also presented.

Additional upper Pleistocene human remains from Vindija cave, Croatia, Yugoslavia.

This report presents a morphological description of ten hominid skeletal fragments found at Vindija cave, northwestern Yugoslavia, in 1980-1981. Eight of the specimens (seven cranial fragments and one complete hand proximal phalanx) were excavated from level G3, a stratum correlated to the Lower Würm stadial and containing Mousterian lithic elements. The salient morphological features of these new specimens are similar to those of previously described hominids from this same stratum, indicating that the new specimens are also remains of archaic H. sapiens (Neandertals). One parietal fragment was excavated from the stratigraphically more recent F complex. The F complex contains Upper Paleolithic lithic elements, and the new hominid specimen from this complex appears to exhibit features similar to other early modern H. sapiens in southcentral Europe.

Chagas' disease in pre-Columbian South America.

The quest for the origin and dispersion of Chagas' disease, the second most important vector-borne disease in Latin America, has epidemiological, immunological, and genetical implications. Conjectures based on accounts of chroniclers, reviews of the archaeological literature and the present distribution of triatomine bugs, the vectors of the disease, held that the origin of the adaptation of Triatoma infestans (a species of the subfamily Triatominae) to human dwellings occurred in prehistoric times. The autopsy of 35 mummies exhumed in the Chilean desert, dated between 470 B.C. and 600 A.D., revealed the presence of clinical manifestations of Chagas' disease and put earlier speculations on a factual basis.

A congenital meningocoele in prehistoric Australia.

This report concerns a congenital meningocoele in a young adult Aboriginal female from north-western New South Wales, Australia. The fact that this individual reached adulthood throws new light on the attitude of these nomadic people towards such conditions. Evidence of this kind may prompt also a re-evaluation by prehistorians and anthropologists of the popularly held belief that all such malformations were automatically eliminated by infanticide. The discovery of this form of pathology helps provide new information not only on past cultural attitudes towards disease, but its frequency and geographical incidence, and adds to our knowledge concerning the range of pathological conditions suffered by prehistoric societies worldwide.

Development and evolution of the helicoidal plane of dental occlusion.

The helicoidal plane of dental occlusion is a composite feature involving axial inclination of teeth and effects of dental attrition. Recent studies disagree on its distribution and significance in hominoid primates. The distribution, development, and functional basis of the helicoidal plane are investigated here, based on quantitative analysis of dental morphology and attrition in 667 human and 60 chimpanzee dentitions. Helicoidal planes are nearly universal in the human and chimpanzee dentitions studied. Increasing axial inclination of molars from M1 to M3 is primarily responsible for the helicoidal plane, although attrition acts to increase its expression. In hominoids, increased molar axial tilt appears to be associated with facial shortening and dental reduction. Population and species comparisons suggest a functional relationship with cranial structure. Progressive axial tilt of molars producing a helicoidal plane is found consistently in mammals with cheek teeth positioned partly under the cranium, as in hominids, pongids, some cebids, macropodids, ursids, and sciurids. Facial shortening is an important trend in hominid evolution and axial inclination of molars might be expected to show progressive change from Australopithecus afarensis to recent Homo sapiens.

Cutmarks on the Engis 2 calvaria?

An examination of the surface morphology of the juvenile Neandertal calvaria, Engis 2, has resulted in the discovery of several series of incised striations. The purpose of this paper is to describe and discuss these striations. A preliminary interpretation of at least some of the striations as cutmarks, made at or near the time of the child's death, is offered.

Porotic hyperostosis in a marine-dependent California Indian population.

A maize-based iron- and protein-deficient diet is commonly cited as the most important cause of porotic hyperostosis among American Indian agriculturalists. An alternative to this maize dependence hypothesis is suggested by the analysis of 432 crania from the nonagricultural, fish-dependent population of the Channel Island area of southern California. Cribra orbitalia, a form of porotic hyperostosis associated with iron deficiency anemia, is just as common among these fisherpeople, whose diet was rich in iron and essential amino acids, as it is among maize-dependent agriculturalists. Northern Channel Island crania have much more cribra orbitalia than those from the California mainland. The highest incidence is on San Miguel, a small geographically isolated island with a shortage of fresh water and terrestrial resources. The Indians who lived on Santa Cruz, the largest of the northern Channel Islands with the greatest diversity of terrestrial plants and animals, have less cribra orbitalia than those who lived on Santa Rosa or San Miguel Island. This geographical distribution appears to be explained by island-mainland and interisland differences in water contamination, exposure to fish-borne parasites, and nutritional adequacy of the diet. The prevalence of porotic hyperostosis in a population with a heavy dietary dependence on marine resources shows that among prehistoric American Indians, this condition is not always associated with an iron- and protein-deficient diet of cultigens. It seems likely that high nutrient losses associated with diarrheal disease are often more significant in the etiology of porotic hyperostosis than a low dietary intake of essential nutrients.

Cut marks on the Bodo cranium: a case of prehistoric defleshing.

Cut marks were discovered on the Middle Pleistocene Bodo cranium from Ethiopia. The cut marks most closely resemble experimental damage caused by the application of stone tools to fresh bone. This discovery constitutes the earliest solid evidence for intentional defleshing of a human ancestor and offers new research avenues for the investigation of early hominid mortuary practices.
