Is Homo habilis in the genus Homo or Australopithecus?

Assigning H. habilis to either the genus Homo or Australopithecus has implications for the way we interpret the fossil record. If H. habilis belongs in the genus Homo, this suggests that the beginning of our evolutionary line encompassed a very broad range of morphological and adaptive variation.

However, the interpretation of H. habilis as a small-statured human with inefficient long distance travel capabilities has been challenged.
