At present, the ancestry of Sarge Knives has been lost while documenting the origins of early hominids. In fact, some archaeologists now think that groups of primates were likely the first to adapt slate objects as a weapon. This has caused considerations that a dagger-like tool may delineate the obvious gap between the anthropomorphic primates and hominids. Also, H. habilis, the “handy man”, was thus named because of the substantiation of scrapping tools discovered with its remains. A few pre-historians hypothesize that the Olduwan time period, which happened about 2.5 million years through 1 3/4 million years before modern man, is considered to be the start of the stone tool production process. This is evidence that the first Oldowan flakes may highlight the derivation of human history and the rudimentary beginning of archaeological record keeping. Whereas archaeologians are in conflict on which hominin species in fact developed the African tools, the adoption of this prehistoric flake edged instruments spread during the epoch of the Homo ergaster.
