The scientific name Pithecanthropus rudolfensis was proposed in 1978 by V. P. Alekseyev[1] who later (1986) changed it to Homo rudolfensis[2] for the specimen Skull 1470 (KNM ER 1470). It remains an open question whether the fossil evidence is sufficient for postulating a separate species, and if so whether this species should be classified as within the Homo or Australopithecus genus.
