Early hominin cladistic relationships. a Cladogram derived from the phylogenetic analysis of Strait and Grine (2004). b Simplified cladogram suggesting that robust australopiths and Homo are closely related to each other. c Simplified cladogram suggesting that robust and gracile australopiths have complex and unresolved relationships but that they are all more closely related to Homo than they are to any of the pre-australopiths
