Researchers from Canada have been studying the Wonderwerk Cave between Kuruman and Danielskuil in the Northern Cape.

The scientists have made interesting discoveries - which include traces of fire residue that dates back to more than a million years ago. The research team, which has set-up a laboratory in the caves, has already published a number of articles in relation to their findings.

Between Kuruman and Danielskuil, in the Northern Cape, lies a massive stone outcropping which marks the entrance to one of humanity's oldest known dwelling places - the Wonderwerk Cave. ... Professor Michael Chazan, an archaeologist at the caves, says since their arrival in 2004, they have made interesting discoveries such as stone tools, fire residue and bones which date back to more than a million years ago. ... Scholars have argued that there isn't enough evidence to suggest that pre-historic humans cooked with fire, but instead ate raw meat.

However, Dr Francesco Berna, who made the fire residue discovery, says the findings are a new stride in the theory of human evolution.
