On the differences between two pelvises of Mousterian context from the Qafzeh and Kebara caves, Israel

Two pelvises from a similar archaeological context have been discovered in recent years in two different caves in Israel. The pelvis from the Qafzeh cave (Qafzeh 9) was dated by means of thermoluminescence at approximately 95 kyr BP. All available measurement values, the most significant being those of the diagnostic obturator region, fall within those of the modern range. The other pelvis emanates from the Kebara cave and differs fundamentally from modern pelvises and from the Qafzeh specimen, although the Kebara pelvis is 30,000 years younger than the latter. As in other remains of Neandertal pelvises, the superior public ramus of the Kebara hominid is extremely long and slender and exhibits a cross section unlike that of modern humans. The absolute height of the obturator region is very small. It is these measurements and proportions that set the Kebara pelvis apart from both modern pelvises and the specimen from Qafzeh. The morphological differences and the chronological relationship between the two fossil pelvises support the concept of two distinct evolutionary lineages for these hominids.
