Early hominin phyletic relationships. Phyletic tree based on cladistic relationships depicted in Fig. 6a. The pre-australopiths give rise to the gracile australopiths, which in turn give rise to both the robust australopiths (Paranthropus) and Homo. The approximate time ranges of hominin species are shown as black bars. Solid lines represent likely ancestor–descendant relationships. Dashed lines represent possible ancestor–descendant relationships
