Beyond this, however, the picture is a little hazy.To some extent, the perspective is complicated by context, for although morphology.Nonetheless, until recently there was room for uncertainty over which thoracic/pelvic condition was derived within the genus (KNM-WT 15000 from West Turkana in Kenya) shows a weakly conical thorax and, as reconstructed, only a modestly wide pelvis (17).
, is highly autapomorphic (uniquely derived) among hominids in the structure of its skull and postcranial skeleton.
It is also sharply distinguished from other organisms by its unique symbolic mode of cognition.
The event concerned was apparently short-term because it is essentially unanticipated in the fossil record.
In contrast, the first convincing stirrings of symbolic behavior are not currently detectable until (possibly well) after 100 Ka.
The fossil and archaeological records combine to show fairly clearly that our physical and cognitive attributes both first appeared in Africa, but at different times.
