Skeletal biology of Apurguan: a precontact Chamorro site on Guam.
The human skeletal remains of a minimum of 152 individuals from the precontact Latte Period (AD 1000-1521) on Guam, Mariana Islands, are described. The sample, recovered at Apurguan, in the Tamuning District, is one of the largest series of well-provenienced Chamorro skeletal remains to be analyzed in recent years. The size and systematic nature of this database are a major contribution to the human biology of the region. Paleodemographic characteristics, dental and skeletal morphology, and paleopathology are presented, along with a limited examination of sex differences in frequencies of nonmetric variation. The mortuary sample, consisting of 51 subadults and 101 adults, exhibits underrepresentation of females, highest subadult mortality between 2 and 10 years, and an adult average age-at-death of 43.5 years. Cranial and infracranial indices and nonmetric variation are consistent with the Chamorro's Southeast Asian origins. There are few statistically significant sex differences in nonmetric variation which suggests close genetic affinity. The frequency of dental pathology overall is low, reflecting a well-balanced, varied diet, and consistent with preagricultural subsistence; however statistically significant sex differences suggest the influence of differential cultural behaviors or resource access. Paleopathological observations include healed fractures (more common in males), little advanced osteoarthritis, evidence for gouty arthritis, and treponemal disease (yaws). One individual, a young adult male, was interred with 10 human bone spear points in situ. Twenty percent of the primary burials exhibit evidence of postdepositional removal of selected skeletal elements for cultural purposes such as keepsakes or raw material.
