"... clear fossil evidence that even the robust australopithecines were
equipped with the muscle flexor pollicis longus, meaning that they had an
excellent precision grip. Fine manipulation therefore clearly preceded brain
expansion. "

australopithecines had cranial capacities in the 500 cc range, which suggests
that brain expansion was occurring in this lineage as well.
