Homo habilis
Being one of the oldest fossils of "Homo habilis", OH 24 has been used to settle many disputes about splitting some of the early "Homo" fossils that have been found into Homo rudolfensis and "Homo habilis", or lumping them together into one single species, "Homo habilis". Some of the highly disputed fossils are KNM-ER 1813 which most agree is a female "Homo habilis" and KNM-ER 1470 which many argue has various anatomical differences to the previously known "Homo habilis" fossils that should make it be classified into the "Homo rudolfensis" species.
