"[a]s early as 75,000 years ago, anatomically modern humans were making finely crafted stone weapon points, carving tools out of animal bones, and engraving symbols on blocks of ochre." researchers found evidence of this in which of the following locations?

Blombos cave, South Africa

Explanation:

The scientists working in Blombos Cave in South Africa’s southern Cape region  made discoveries that changed the understanding of when the human ancestors started expressing themselves through drawings. A 73 000-year-old cross-hatched drawing was found on a silcrete (stone) flake. It was made with an ochre crayon.

Older layers at Blombos Cave, dated at 100 000 years, discoveries were found of a complete toolkit consisting of two abalone shells filled with an ochre rich substance – a red paint – and all the artefacts associated with making it including seal bone used to add fat to the mixture. This discovery proves that the early ancestors could also make paint by 100 000 years ago.

Engraved ochre slabs with various designs, including cross-hatched patterns, were also found in these older layers.
