In 84% of the taxa observed, mesial cristids were well developed and provided incisor-like occlusion with di2. In 5 of the remaining 8 taxa, lingual cristids provided incisor-like occlusion with dc1. Comparisons between dc1s and C1s of conspecific adult males and females show that in 85% of the species observed the magnitude of mandibular canine incisor traits follows this order: deciduous > adult female > adult male. This within-species variation is inversely related to the likely adaptive value of the canine as a weapon and to canine crown height. A selection model based on these data is derived and applied to human canine evolution. The relevance of these data to the field vs. clone theory debate about dental development is also discussed.</p>","PeriodicalId":76854,"journal":{"name":"Zeitschrift fur Morphologie und Anthropologie","volume":"79 1","pages":"103-20"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12612650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes, illustrates, and tabulates the frequencies of such structures by age and sex in a large collection of Pan troglodytes verus skulls. In the overall sample of 263 skulls where the region could be observed, these protuberances of bone occur bilaterally in 10.7% of specimens and unilaterally in an additional 3.4%. They increase in frequency with age to a high of 16.9% in adult and older animals. Among adult specimens, these projections of bone in the anterior nasal region are present more commonly in females than in males.

Comparison of estimates made from anterior microscopic fields versus peripheral fields (N = 29 femora) indicates general age agreement, with 6/29 demonstrating marked differences between sampling locations. Three cases of unilateral trauma show no consistent effect on bone age estimates. Among sixteen adults of known age, the ages of eight were accurately estimated; five were estimated to be significantly older and three were estimated to be younger than they were. It is argued that cortical erosion/diagenetic destruction may contribute to overestimation by obscuring the periosteal regions required for application of the technique.

A combination of length and width measurements provided a more accurate estimation than each measurement individually. When taken alone, length produced a more accurate estimation than width. Sex and age factors are useful for the estimation of stature, though these variables are often unknown in the isolated bone. The samples are divided into immature and mature groups (according to skeletal maturity). Regardless of sex, stature could be estimated from the metacarpal length and width with a standard error of 4.19 cm by means of a multiple linear equation in the immature group. The mature group should be considered with adults for this purpose. Thus, taking into account their skeletal maturity, living stature could be practically estimated from the second metacarpal with significant degrees of accuracy in children.</p>","PeriodicalId":76854,"journal":{"name":"Zeitschrift fur Morphologie und Anthropologie","volume":"79 1","pages":"11-20"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12612652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
