KNM ER 1470, Homo rudolphensis

First discovered in Koobi Fora, Kenya is 1972, Homo rudolphensis has consistently been the subject for debate. Many anthropologists believe this specimen to belong to the Australopithecine genus while some favor Homo habilis as its species. There are many features used to distinguish this sole specimen (KNM ER 1470) from both of these groups, but a consensus has yet to be reached.
