SOUTHERN AFRICA AND MODERN HUMAN ORIGINS, 1992, Deacon Hj,
This paper argues that southern Africa was a remote part of the Old World in the late Pleistocene (125-10 ka ago). Because of this isolated position there was continuity without significant replacement in the resident population. Isolation and the relatively recent spread of agriculture to the region has allowed a section of this population to survive into the present. They are the Bushmen (San). Studies of geographic patterning in conventional genetic markers and mitochrondrial DNA indicate that the Bushman clade has a long evolutionary history in southern Africa. Estimates of more than 100 ka for the continued presence of this population in the region are supported in archaeological investigations of sites with long sequences such as Klasies River main site and Border Cave. Human remains dating to the earlier part of the late Pleistocene have been recovered from these sites and the samples form a morphological series with the Klasies River remains possibly 20 ka older than those from Border Cave. There is no fossil record for the later Pleistocene, however, at a period when selection for a gracile morphology may have been pronounced. The cultural associations in the earlier late Pleistocene are with the Middle Stone Age. Expressions of cultural 'style' and the occurrence of similar artefact design types in the Middle and Later Stone Ages can be interpreted with reference to the ethnographic present. Temporal continuity can be shown in the geographical distribution of stylistic markers and this suggests participation in a shared cognitive system. The inference is that the people in the earlier late Pleistocene had cognitive abilities that are comparable to those shown by their Holocene and modern descendants. The presence of the ancestors of a modern population in the earlier late Pleistocene in this region is perhaps expected if modern people had their origins in Africa

Morphological affinities of the proximal ulna from Klasies River main site: Archaic or modern?, 1996, Churchill Se, Pearson Om, Grine Fe, Trinkaus E, Holliday Tw,
The Middle Stone Age (MSA) asociated hominids from Klasies River Mouth (KRM) have taken on a key role in debate about the origins of modern humans, with their craniofacial remains seen as either representing the earliest well-dated modern humans in southern Africa or orthognathic late archaic humans. Diagnostic postcranial remains from Klasies are few, but one specimen-a proximal right ulna from the lower SAS member-is useful For assessing the morphological affinities of these hominids. Canonical variates analysis using 14 proximal ulnar dimensions and comparative data from European, west Asian and African archaic humans, and Levantine Mousterian, European Upper Paleolithic, African Epipaleolithic and diverse recent modern human samples (many of recent African descent) were employed to assess the morphological affinities of this specimen. Results suggest an archaic total morphological pattern for the Klasies ulna. Analysis of diaphyseal cross-sectional geometry reveals an ulnar shaft with relatively thick cortical bone, but the specimen cannot be readily distinguished from Neandertals or early anatomically modem humans on the basis of shaft cross-sectional properties. If the isolated ulna from Klasies is indicative of the general postcranial morphology of these hominids, then the MSA-associated humans from KRM may not be as modern as has been claimed from the craniofacial material. It ii: possible also that the skeletal material from KRM reflects mosaic evolution-retention of archaic postcranial characteristics. perhaps indicating retention of archaic habitual behavior patterns, in hominids that were becoming craniofacially modern.

Morphology of the border cave hominid ulna and humerus, 1996, Pearson O. M. , Grine F. E. ,
Hominid bones from Border Cave (BC) have been the subject of controversy with regard to the question of modern human origins. New dating assays suggest that while some of the BC remains are of comparatively recent age (i.e. < 20 kyr), several postcranial fragments derive from the Middle Stone Age (MSA) layers. Among the latter, a proximal ulna in comparable to one from the MSA at Klasies River Mouth, in that both have an archaic pattern of morphology in the relative height of the coronoid and olecranon processes. This configuration appears to characterize Neandertals, and is displayed also by more ancient African ulnae. The BC humeral diaphysis has moderately thick cortical bone, but us otherwise unremarkable. The proximal ulnar morphology might suggest that the MSA inhabitants of South Africa engaged in activities similar to those of Neandertals and other postcranially archaic hominids. If the modern-looking BC-1 cranium in contemporaneous with the BC postcranial bones, this would bear testament to the mosaic nature of human evolution. Alternatively, if BC-1 proves to be of recent derivation, and the postcrania are as old as the base of the BC MSA sequence has been claimed to be (c. 195 kyr), they might have been associated with more archaic crania (perhaps similar to Florisbad). Final resolution of these questions awaits determination of the absolute ages of the BC-1 cranium and the BC postcranial bones

A mineralogical and phytolith study of the middle stone age hearths in Sibudu Cave, KwaZulu-Natal, South Africa, 2004, Schiegl S. , Stockhammer P. , Scott C. , Wadley L. ,
Sediments from Middle Stone Age hearths and burnt deposits in Sibudu Cave (KwaZulu-Natal, South Africa) were analysed for their mineral and phytolith contents. The mineral compositions were determined by FT-IR spectroscopy. The phytoliths were classified and counted by transmitted polarized light microscopy. Burning experiments using wood and grasses from species native to the cave's environment yielded the reference ashes. The visible hearths and ash dumps contain phytolith assemblages characteristic of wood fuel. A significant portion of the phytoliths of hearths and ash layers display morphologies related to intense heating. This finding is suggestive of long-burning wood fires and/or reuse of the same fireplace. The heat-altered phytoliths are useful in tracing fires, especially if hearth structures are not preserved and ash deposits have been diagenetically and heavily altered. The phytolith contents and mineralogical composition of the ash deposits and the surrounding sedimentary matrix are very similar. This feature suggests that the sedimentary matrix originally contained fireplaces and ash deposits, whose structures were destroyed shortly after deposition, presumably by trampling.(21) The intact circular hearths are most likely the product of intense fires. Similar results from hearths and their surrounding matrix have been reported from Middle Palaeolithic cave sites in Israel
