RESUMO

OBJECTIVE: Little attention has been given, so far, to the early colonial diet in New France from an isotopic perspective. Historical records that compare France to New France suggest a shift toward a more diverse diet, including a higher protein intake due to an improvement in living conditions in the New World, despite the retention of ancestral dietary habits. This hypothesis will be explored here. MATERIALS AND METHODS: Stable carbon (organic and mineral) and nitrogen isotopes were measured on 43 individuals from Notre Dame cemetery (first Catholic parish church cemetery in Montreal, 1683-1803) as well as 13 French compatriots from La Rochelle, France (Protestant Hospital Cemetery, 1765-1792). Intragroup variation (age at death, sex, and/or burial location) was investigated and compared to compiled data from various northeastern North American sites (N = 99). RESULTS: The Notre Dame sample means are as follows: -19.6‰ versus VPDB for δ13 Ccollagen , -12.22‰ versus VPDB for δ13 Ccarbonate , and 11.5‰ versus AIR for δ15 N. They are significantly lower than both La Rochelle (-18.4‰, -11.67‰, and 12.7‰, respectively, p ≤ .005) and the northeastern North American groups used for this comparison (p = .000). DISCUSSION: The isotopic values obtained from Notre Dame cemetery suggest that the diet was mainly based on C3 resources with limited C4 resources. Although different from all comparable contemporary sites, colonial Montreal's diet remains most similar to La Rochelle, France. This study agrees with historians who have suggested that French dietary traditions seem to have been retained among the early colonial inhabitants of Montreal.

RESUMO

Although questions of modern human origins and dispersal are subject to intense research within and outside Africa, the processes of modern human diversification during the Late Pleistocene are most often discussed within the context of recent human genetic data. This situation is due largely to the dearth of human fossil remains dating to the final Pleistocene in Africa and their almost total absence from West and Central Africa, thus limiting our perception of modern human diversification within Africa before the Holocene. Here, we present a morphometric comparative analysis of the earliest Late Pleistocene modern human remains from the Central African site of Ishango in the Democratic Republic of Congo. The early Late Stone Age layer (eLSA) of this site, dated to the Last Glacial Maximum (25-20 Ky), contains more than one hundred fragmentary human remains. The exceptional associated archaeological context suggests these remains derived from a community of hunter-fisher-gatherers exhibiting complex social and cognitive behaviors including substantial reliance on aquatic resources, development of fishing technology, possible mathematical notations and repetitive use of space, likely on a seasonal basis. Comparisons with large samples of Late Pleistocene and early Holocene modern human fossils from Africa and Eurasia show that the Ishango human remains exhibit distinctive characteristics and a higher phenotypic diversity in contrast to recent African populations. In many aspects, as is true for the inner ear conformation, these eLSA human remains have more affinities with Middle to early Late Pleistocene fossils worldwide than with extant local African populations. In addition, cross-sectional geometric properties of the long bones are consistent with archaeological evidence suggesting reduced terrestrial mobility resulting from greater investment in and use of aquatic resources. Our results on the Ishango human remains provide insights into past African modern human diversity and adaptation that are consistent with genetic theories about the deep sub-structure of Late Pleistocene African populations and their complex evolutionary history of isolation and diversification.

RESUMO

The purpose of this study was to evaluate the distribution and incidence of two forms of alveolar bone resorption known as fenestration and dehiscence across time and space. To accomplish this a Medieval French population was studied and the results were compared with other studies to examine incidence and distribution of alveolar bone resorption. Thus, 1175 teeth were analysed for 81 individuals, from an agropastoral Medieval (12th-14th century) archaeological site of Vilarnau located in the South of France. Tooth presence and absence as well as dental alveolar resorption were recorded. A new standardised methodological approach to record alveolar resorption is presented and can be used for any skeletonised series. Measurements of dehiscence were made in the midline on each root in relation to the cemento-enamel junction and fenestration was considered as resorption restricted to alveolar bone. Through analyses of the distribution and incidence of alveolar bone resorption over-time in a Medieval French population, along with nine other studies, we present a list of predictive factors for alveolar bone resorption. Among these factors tooth position and function were the most important; anterior teeth were more commonly affected, bone resorption was more common on the labial/buccal versus palatal/lingual surfaces, fenestration was also more common on the maxilla and dehiscence on the mandible (p≤0.001). These patterns do not vary through time or space, and therefore, provide predictive factors for health practitioners in oral therapy to improve patient recovery and post oral treatment success.

RESUMO

As the identity of a large number of Khoe-San skeletal material in European collections recently came into question during its documentation, a re-evaluation of the remains by employing a non-invasive method such as craniometrics was done to investigate the biological affinity. For this purpose, gene flow and population diversity present within the group, as well as between the study sample (N=63) and other modern and historic population groups from southern, central and east Africa were explored. Available comparative groups included the historic Khoe-San from Riet River (N=31), the Sotho-Tswana from southern Africa (N=61), the Basuku from central Africa (N=66) and the Bahutu (N=53) and Teita (N=24) from east Africa. Ten craniometric variables were selected and used to perform population structure analysis based on model bound quantitative genetics and multiple discriminant function analysis (MDA). Quantitative genetic distances revealed that the Khoe-San sample was closest to the Riet River group. Residual variance analysis performed on two-sample subsets of the Khoe-San group (Cape KS and Various KS) showed a higher level of heterogeneity in the Cape KS than seen in the Khoe-San from various other areas in southern Africa. MDA revealed that Khoe-San intra-sample variance is relatively high, with 44% of the sample (sexes pooled) classified into the Riet River group. The remaining individuals were classified (in decreasing order) into Bahutu (24%), Basuku (24%) and Sotho-Tswana (8%). Although the Khoe-San specimens are closest to the Riet River group, they are clearly not homogenous. Their high level of phenotypic diversity most likely originated from a complex population history involving many group interactions driven by social and political marginalization.

RESUMO

The lack of Late Pleistocene human fossils from sub-Saharan Africa has limited paleontological testing of competing models of recent human evolution. We have dated a skull from Hofmeyr, South Africa, to 36.2 +/- 3.3 thousand years ago through a combination of optically stimulated luminescence and uranium-series dating methods. The skull is morphologically modern overall but displays some archaic features. Its strongest morphometric affinities are with Upper Paleolithic (UP) Eurasians rather than recent, geographically proximate people. The Hofmeyr cranium is consistent with the hypothesis that UP Eurasians descended from a population that emigrated from sub-Saharan Africa in the Late Pleistocene.
