We should not let scientific theories and discoveries influence our deen since belief in it may be inconsequential and if a theory or discovery is proven to be false (as is the norm in the scientific community), then some of us would end up defending something that is alien to Islam to begin with. What we can see from this, as brother NNoor pointed out, is that the theory of human evolution continues to "evolve" itself. It has been the consensus amongst evolutionists that the first Homo sapiens appeared 400,000 years ago. This theory suggests that it may have been earlier, overlapping with many of the earlier Homo species. These earlier "species" were considered to lack any real sense of intelligence so to actually discover fire is something that seems uncharacteristic of them. There are even other holes that exist, such as the earliest primitive tools that exist predate the supposed advent of the Homo species and subspecies.
