The human vocal apparatus is part of a vertically integrated system, and I agree with Licbennan that modern high-speed phonology co-evolved with our capacity for grammar. Olson and I agree that some distinctly human thought skills appear to be fairly recent cultural acquisitions related to the introduction of new symbolic technologies and external (that is, nonbiological) memory storage. Stenning's concern with my use of the term “episodic” can be resolved by distinguishing between episodic storage and retrieval. Baum's suggestions regarding courtship and cognitive evolution seem to apply better to mimetic expression than to language.
