Directional bilateral asymmetries in human gross skeletal morphology are largely attributable to differential mechanical loading from handedness during endochondral bone growth. While much has been done in the way of identifying directional asymmetries of the upper limb in relation to handedness, comparatively little research has focused on asymmetry in the lower body. The present paper analyses asymmetry in the human sacrum in a sample of 238 modern individuals. Measurements of right and left sides of the lateral and posterior breadths of the alae and the maximum height of the auricular surface were used. Asymmetry was calculated as: [(left side − right side) ÷ right side] * 100. Directional asymmetry was identified using a one‐sample t‐test against a hypothesized mean of zero. Significant directional asymmetry (P < 0.05) was found in all three dimensions. The pattern of asymmetry is consistent with models describing the influence of right‐handedness on the lower body, which predicts that left side dimensions will be larger.

During the excavation and analysis of a 6th-century AD vessel in Tantura Lagoon, Israel, members of the joint Institute of Nautical Archaeology and Center for Maritime Studies team located an Arab-Period vessel in the vicinity. The dating of the vessel to the 8th–9th century AD is based on pottery, found in association with timbers. Only a matter of days before the end of the excavation season, one end of the vessel was unearthed and preliminary recordings, drawings, and photographs were made. None of the timbers were removed from their in-situ positions for analysis as both time and facilities were not permitting. Though a full analysis was not possible, information gleaned during the several days of recording affords an understanding of the ship's construction. 相似文献
