Implications of Border Cave Skeletal Remains for Later Pleistocene Human Evolution [and Comments and Reply

Abstract

Recent excavations have helped to clarify the cultural and stratigraphic sequences at Border Cave, and human skeletal remains recovered at this South African site may well be associated with a Middle Stone Age industry. A partial adult cranium is of particular interest, and this was originally described as quite different both from African Negro and from Bushman individuals. Eleven measurements were taken on the fossil, and these provide a basis for comparison of Border Cave with other crania drawn from extant African populations. Discriminant analysis shows clearly that the cranium lies close to the Hottentot male centroid and is within the range of modern African variation for the measurements employed. It is heavily constructed but not archaic in the fashion of Florisbad or Broken Hill. If the case for antiquity is regarded as firm, then the Border Cave skeleton suggests the presence of Homo sapiens sapiens in southern Africa before 50,000 B.P. and perhaps as early as 115,000 B.P. Hottentot or Bushman-like people may thus have inhabited southern Africa for a long time. This would be consistent with a phyletic view of human evolution, postulating an in situ transition from archaic to more modern man. Whether migration and replacement of populations may have occurred elsewhere is another question, and there is no reason to exclude this as a possibility on a local level, even if waves of replacement did not sweep the Old World late in the Upper Pleistocene. The course of evolution outside of southern Africa cannot be determined from the evidence considered here.
