Red ochre and shells: clues to human evolution:

Recent discoveries providing evidence of an early [> 200ka; 1ka=1000 years before present (BP)] and independent development of symbolic expression in modern humans and Neanderthals [15] have important implications for our understanding of human evolution. This evidence relies heavily on the ornamental use of shells and red ochre [17], whose combined use by humans elapses over 200ka

Many Middle Stone Age sites in South Africa yielded hundreds, even thousands, of ochre pieces sometimes showing use traces. Less attention has been paid to the tools used for their processing. Here, seven tools excavated from the oldest layers (71,000 to 77,000 years ago) of Sibudu rock shelter were studied non-invasively to identify the micro-residues on them.
