Australopithecus sediba
From RationalWiki
Australopithecus sediba was possibly another transitional species between humans and apes. Sediba could climb better than later hominids but also walked upright.[citation needed] Its brain was relatively small, possibly smaller than average for Australopithecus afarensis. [1] A. sediba had a relatively human-like hand with a grip which may indicate tool use[citation needed]. There is considerable uncertainty about sediba and even a suggestion that the species should be included in the genus Homo.[2][3][4][5]
