Hawks suggests that this impediment results from several aspects of cladistic analysis, including the undeniably (1) limited number of fossils available for examination, which in turn, results in a (2) limited number of characters that can be observed, (3) ambiguities in the definitions of hominid characters, which, is in part due to the (4) close relationship of the taxa, in addition to an overall (5)...
