Tj Figures 16-21 pres variation in the means of thevanSH^B Boomplaas A. It is clear that there is consideraoi^ of the various populations and, in particular, the good sequence «t _ A shows clear trends. Figure 15 shows that the pattern of size change in the mandible of C. flavescens at Boomplaas A is very similar in all the parameters measured. This would suggest that, in fact, the mandible was changing in overall size rather than in one aspect alone. Until such time as the nature of the relationship of the size of the mandible to overall body mass is established for this species, it will be assumed that a larger mandible indicates greater body mass. In general terms, on this basis, C. flavescens is shown to be larger during the Upper Pleistocene than during the Holocene. The only exception is level BOL where the means are smaller than those for the earliest part of the Holocene sequence. Larger samples for level BOL may clarify th
