但是这个南方古猿谱系的特性，以及早期人属的特征都是未知的。
But the identity of that lineage, and the characteristics of early Homo, are unknown.
李·伯格尔博士推断南方古猿sediba可能直接进化成了直立人，这使“能人”成为进化的旁支，甚至不是人属的一部分。
Dr Berger posits that sediba may have evolved directly into Homo erectus, leaving habilis as an evolutionary sideline, and not even part of the genus Homo.
如果距今200万年的南方古猿源泉种确实是人属的真正祖先，它怎么可能繁衍出比尔·吉姆贝尔（威廉·吉姆贝尔？）鞋盒子中距今历史更长的化石人属？
If two-million-year-old A. sediba is indeed the true ancestor of Homo, how could it give rise to those even older fossils assigned to Homo in Bill Kimbel's shoe box?
时间轴的另一端是人属，考虑到著名的南方古猿阿法种露西(LucyAustralopithecus afarensis)，人属可以认为是最接近于人类的第一种生物。
On the timeline's other side is the Homo genus, the first creatures whom one would recognize - with all due respect to Lucy's famous A. Afarensis - as close to human.
同时，亚利桑那州立大学(Arizona State University)的古人类学家威廉·金贝尔(William Kimbel)主张，虽然sediba可能不是人类的一个直系祖先，但还是应当归为人属这一类，而非南方古猿。
Meanwhile, Arizona State University paleoanthropologist William Kimbel argued that A. sediba should have been classified as Homo, though it may not have been a direct human ancestor.
作为南方古猿的一个属，sediba要比尚未命名的西伯利亚的发现更不像人。西伯利亚的发现属于人属。
As a member of the genus Australopithecus, sediba is less manlike than the as-yet-unnamed Siberian discovery, which was a member of the genus Homo.
