How would our engine for decoding pitch ratios help with survival.

By forming the rudiments of what would eventually become language, and
an ability to communicate...think dolphins, elephants, bird calls,
etc...even if it's something as simple as a mating call...or perhaps
more to the Darwinian point, exactly something like a mating
call...species survival-wise.

Good point, Rufus. I think that much of language is based more on
formants/filtering of noise-like sources rather than pitch, but maybe
the ability to discern harmonic relationships was a refinement. The
ability to decode music seems far beyond that though.
