If the Hadar jaw really is Homo, says Berger, then perhaps its dating is wrong-a contention Kimbel disputes as vigorously as he supports the validity of his fossil.
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.
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。
