The existence of H.Floresiensis suggests that even very primitive morphological platforms of hominid had the capacity to survive - this really means we stopped needing to evolve a long time ago. If we take modern sapiens out of the picture, it looks to me like a much more natural diversification of stable morphology - it's when we include modern sapiens that the neanderthal, ergaster, early erectus etc, seem likely to have been superseded by superior evolutionary traits. That Floresiensis exists at all suggests we should be swamped in fossilized varieties of the homo genus since it's departure from apes!
