Perhaps for the same reasons that they didn't develop our level of
general intelligence, language, etc. Maybe it's all somehow a package
- a group of reinforcing traits that are only really useful all
together (co-evolving incrementally?), and require some particular
environmental stimulus to trigger off (a stimulus which presumably
chimps and pygmy chimps didn't share with us).
