In Blombos Cave in South Africa, researchers uncovered shell beads from 75,000 to 72,000 years ago that show relatively rapid changes in how they were designed, ScienceNOW reported.

The ornaments themselves, small and rounded African tick shells called Nassarius kraussianus, were consistent. But shells in different archeological layers appeared to have been strung together in different patterns.

The researchers measured this variation by looking at patterns of wear on the shells. The ancient people appeared to have punched holes in them with bone tools in order to string them together, and by looking at asymmetrical wear around the holes the researchers were able to establish their orientation. They also looked at patterns of rubbing on other parts of the shells.

In order to interpret the patterns of wear, they took modern shells, strung them together in different ways, and subjected them to stress, putting them in solutions that mimicked human sweat and tumbling ...
