“…Although there is evidence that molar wear rates across fossil populations are reasonably comparable (22,30), this conclusion has not been established across earlier fossil species, especially those with specialized diets like the robust australopithecines. However, the dietary specializations and associated craniofacial architecture among australopithecines that could contribute to greater tooth wear are also associated with larger teeth and thicker enamel that reduce rates of wear, and there is no direct evidence that wear rates are faster in the more specialized australopithecines.…”

Increased longevity, expressed as number of individuals surviving to older adulthood, represents one of the ways the human life history pattern differs from other primates. We believe it is a critical demographic factor in the development of human culture. Here, we examine when changes in longevity occurred by assessing the ratio of older to younger adults in four hominid dental samples from successive time periods, and by determining the significance of differences in these ratios. Younger and older adult status is assessed by wear seriation of each sample. Whereas there is significant increased longevity between all groups, indicating a trend of increased adult survivorship over the course of human evolution, there is a dramatic increase in longevity in the modern humans of the Early Upper Paleolithic. We believe that this great increase contributed to population expansions and cultural innovations associated with modernity.

“…The age at death for the nonadult individuals was estimated based on the accelerated dental formation chronology previously proposed for Neandertal populations (22). Among the adults, different categories have been distinguished (young adult, adult, and mature) based on the differences of the degree of occlusal dental wear following wear stages (23). For postcranial immature remains, age at death was estimated following methods of bone growth (24).…”

The remains of 12 Neandertal individuals have been found at the El Sidrón site (Asturias, Spain), consisting of six adults, three adolescents, two juveniles, and one infant. Archaeological, paleontological, and geological evidence indicates that these individuals represent all or part of a contemporaneous social group of Neandertals, who died at around the same time and later were buried together as a result of a collapse of an underground karst. We sequenced phylogenetically informative positions of mtDNA hypervariable regions 1 and 2 from each of the remains. Our results show that the 12 individuals stem from three different maternal lineages, accounting for seven, four, and one individual(s), respectively. Using a Y-chromosome assay to confirm the morphological determination of sex for each individual, we found that, although the three adult males carried the same mtDNA lineage, each of the three adult females carried different mtDNA lineages. These findings provide evidence to indicate that Neandertal groups not only were small and characterized by low genetic diversity but also were likely to have practiced patrilocal mating behavior.patrilocality | kinship | demography | human evolution

“…Neither the degree of occlusal wear, nor the mesial or distal position on the tooth, nor the individual age were found to be statistically significantly associated (Table 3). Furthermore, the deepest grooves were found on teeth with slight degrees of occlusal wear [Stages 2-3 of Skinner (1997); see Fig. 4].…”

The distribution of subvertical grooves on interproximal wear dental facets from the El Sidrón (Asturias, Spain) Neandertals is described and analyzed. Out of 93 teeth, 64.5% present subvertical grooves, including a high frequency (50%) on the anterior dentition. Contrary to some studies, subvertical grooves from adjacent facets perfectly overlap each other and do not interdigitate, probably forming small channels. Both the facet and the groove surface share the same polished appearance, suggesting a common origin. Statistical analyses reveal that the number of grooves is neither dependent on the degree of occlusal wear, nor on the position on the tooth or the individual's age. However, facet width is an important factor determining the number of subvertical grooves. The etiology of subvertical grooves formation on Neandertal teeth remains unclear.
