Australia’s oldest human remains, found at Lake Mungo, include the world’s oldest ritual ochre burial (Mungo III) and the first recorded cremation (Mungo I). Until now, the importance of these finds has been constrained by limited chronologies and palaeoenvironmental information. Mungo III, the source of the world’s oldest human mitochondrial DNA, has been variously estimated at 30 thousand years (kyr) old, 42–45 kyr old and 62 +/- 6 kyr old. while radiocarbon estimates placed theMungo I cremation near 20–26 kyr ago. Here we report a new series of 25 optical ages showing that both burials occurred at 40 +/- 2 …

Even by archaeological standards, Blombos Cave is a modestly sized shelter. Yet artifacts recovered from just 13 cubic meters of deposit inside transformed our understanding of when our species developed behavioral attributes we associate with “modern” humans.

That is more than 35,000 years before anything comparable emerged in Europe.
