===Classification=== With the apparent emergence of the genera ''[[Homo]], [[Kenyanthropus]]'', and ''[[Paranthropus]]'' in the genus ''Australopithecus,'' [[Taxonomy (biology)|taxonomy]] runs into some difficulty, as the name of species incorporates their genus. According to [[cladistics]], groups should not be left [[paraphyletic]], where it is kept not consisting of a common ancestor and all of its descendants.<ref>{{Citation|last=Kimbel|first=William H.|chapter=The Species and Diversity of Australopiths|date=2015|pages=2071β2105|editor-last=Henke|editor-first=Winfried|publisher=Springer Berlin Heidelberg|language=en|doi=10.1007/978-3-642-39979-4_50|isbn=9783642399787|editor2-last=Tattersall|editor2-first=Ian|title=Handbook of Paleoanthropology}}</ref><ref>{{Cite book|url= https://books.google.com/books?id=--PNXm0q2O8C&pg=PA364 |page=364 |title=Primate Adaptation and Evolution|last=Fleagle|first=John G.|date=2013-03-08|publisher=Academic Press|isbn=9780123786333|language=en}}</ref><ref>{{Cite journal|last=Schwarz|first=J.H.|s2cid=12944654|date=2004|title=Barking up the wrong ape--australopiths and the quest for chimpanzee characters in hominid fossils|journal=Collegium Antropologicum|volume=28|issue=Suppl 2 |pages=87β101|pmid=15571084}}</ref><ref>{{Cite journal|last=Cartmill|first=Matt|title=A sort of revolution: Systematics and physical anthropology in the 20th century|journal=[[American Journal of Physical Anthropology]]|language=en|volume=165|issue=4|pages=677β687|doi=10.1002/ajpa.23321|pmid=29574829|hdl=2144/29233|year=2018|doi-access=free|hdl-access=free}}</ref><ref name=":0">{{Cite journal|last=Villmoare|first=Brian|date=2018-01-30|title=Early Homo and the role of the genus in paleoanthropology|journal=[[American Journal of Physical Anthropology]]|language=en|volume=165|pages=72β89|doi=10.1002/ajpa.23387|pmid=29380889|issn=0002-9483|doi-access=free}}</ref><ref>{{Cite web|url= https://www.researchgate.net/publication/267552437|title=2 @BULLET Enhanced cognitive capacity as a contingent fact of hominid phylogeny|website=ResearchGate|language=en|access-date=2019-01-12}}</ref> Resolving this problem would cause major ramifications in the nomenclature of all descendent species.
