“…A number of studies have been conducted on the time frame for the ossification of the medial clavicular epiphyseal cartilage in the age group concerned for forensic age diagnostics in living individuals. One group of studies adopted an anatomical perspective, assessing ossification by means of autopsy or direct skeletal inspection (Todd & D'Errico, 1928;McKern & Stewart, 1957;Owings Webb & Myers Suchey, 1985;MacLaughlin, 1990;Ji et al, 1994;Black & Scheuer, 1996;Shirley, 2009;Singh & Chavali, 2011), while the other group took a radiological approach. Several authors pointed out, that data from dry bone material are not directly comparable with data from radiological studies.…”

“…Some studies are less strictly anthropological and focus on the determination of the age at death of an individual (Szilvá ssy, 1980;Walker and Lovejoy, 1985;Webb and Suchey, 1985;Stout and Paine, 1992) or the sex through forensic analysis of the clavicle, in whole or in part (Jit and Singh, 1966;Steel, 1966;Kaur and Jit, 1990;Murphy, 1994;Zhang and Han, 1994;Zhang and Tian, 2001). Relatively few studies have approached Primate clavicular morphology from a comparative or functional perspective (e.g., Schultz, 1930;Olivier, 1953;Cave, 1961;Jenkins, 1974;Fleagle, 1978;Jenkins et al, 1978;Ljunggren, 1979;Harrington et al, 1993;Voisin, 2000aVoisin, , 2000bVoisin, , 2001Voisin, , 2004Voisin and Balzeau, 2004).…”

In spite of its importance for movements of the upper limbs, the clavicle is an infrequently studied shoulder bone. The present study compares clavicular morphology among different extant primates. Methods have included the assessment of clavicular curvatures projected on two perpendicular planes that can be assessed overall as cranial and dorsal primary curvatures. Results showed that in cranial view, three morphologies can be defined. One group exhibited an external curvature considerably more pronounced than the internal one (Gorilla, Papio); a second group was characterized by an internal curvature much more pronounced than the external one (Hylobates, Ateles); and a third group contained those with the two curvatures equally pronounced (Pan, Homo, Pongo, Procolobus, Colobus). Clavicle curvatures projected on the dorsal plane could be placed into four groups. The first group is characterized by two curvatures, an inferior and a superior (Apes, Spider monkeys). The second included monkeys, whose clavicles have an inferior curvature much more pronounced than the superior one. The third group includes only Hylobates, whose clavicles possess only the superior curvature. The last group includes only modern humans, whose clavicles show only the inferior curvature, which is less pronounced than that which exists in monkeys. Curvatures in cranial view relate information regarding the parameters of arm elevation while those in dorsal view offer insights into the position of the scapula related to the thorax. The use of clavicular curvature analysis offers a new dimension in assessment of the functional morphology of the clavicle and its relationship to the shoulder complex.

“…The original method of Lovejoy et al (1985) estimates the age of individuals older than 20 years and divides these into the age groups 20-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-59, and 60 + corresponding to the eight modal stages. The samples used in this study include the individuals aged 15-19 years that can be estimated based on the criteria of dental development (Ubelaker, 1989), the degree of development and closure of the occipital synchondrosis (Wakebe, 1990), and the degree of ossification and epiphyseal union of the pelvis and long bones (Flecker, 1942;Webb and Suchey, 1985). Furthermore, the number of individuals in each of stages 7 and 8, which correspond to 50-59 and 60 +, respectively, were divided into two, which were then assigned to the age categories of 45-54 and 55-64 in the case of stage 7, and 55-64 and 65 + in the case of stage 8.…”

The demography of the Jomon people was first systematically investigated by Kobayashi ([1967] Journal of the Faculty of Science, The University of Tokyo, Section V, 3: 107-162). His lifetable analysis indicated that Jomon life expectancy at the age of 15 was only 16 years. However, recent advances in palaeodemography have questioned whether the reconstruction of demographic parameters from skeletons actually reflects the real mortality patterns of past populations. The purpose of this study is to test the hypothesis that palaeodemographic data from skeletal remains represent an appropriate adult mortality profile. If the hypothesis is the case, the mortality profile of the Jomon people implied the heavy work-load resulting in the unusually high mortality schedule. If it is not the case, on the other hand, Kobayashi's data had been distorted by the errors of adult age-at-death estimation. This study examined well-preserved auricular surfaces of 86 individuals, which are individuals aged 15 years and above. Age estimation of the auricular surfaces was performed using two techniques: the original method of Lovejoy et al. ([1985] American Journal of Physical Anthropology, 68: 15-28) and the revised method of Buckberry and Chamberlain ([2002] American Journal of Physical Anthropology, 119: 231-239). The results indicate important findings on the mortality profile of the Jomon people. First, the revised estimation has older age distributions, with the majority of individuals over 65 years of age. Second, the revised estimation increases the life expectancy at the age of 15 from 16 years to 32 years. The present data lead to the conclusions that the revised method improves the accuracy of age estimation for elderly adults, and that the Kobayashi's estimation does not represent the real mortality profile. These findings will have great effects on the life history reconstruction of the Jomon people.
