No, the evolutionary shift occured prior to the use of fire by a about million years. And, yes it is known for certain, or at least as certainly as we can know anything about events 3 million years ago! The evidence include the reduction of our canines, the existance of butchering creches with stone tools in Africa. Since most of the differnces between Hominids and other Great Apes can be explained on the basis of a shift from opportunistic to regular feeding on meat, it seems fairly well established. (BTW baboons are not great apes, and are not particularly closely related to Human ancestry. In fact they may represent a parallel evolutionary line heading down the same herbivore to carnivore transition we did) -- Sarima (Stanley Friesen) {trwrb|allegra|cbosgd|hplabs|ihnp4|aero!uscvax!akgua}!sdcrdcf!psivax!friesen or {ttdica|quad1|bellcore|scgvaxd}!psivax!friesen
