I recall reading Nagel's "What is it like to be a bat?" paper and
imagine that bats probably construct a map of the world from auditory
signals (and dogs probably do to a great extent through smell).
So the DNA does differ and, expectedly, functionality is somewhat different.
So it's a scoping thing. Is the function to build a memory map of the
world, and contain predisposition toward particular sorts of behavior in
relation to it (the map) or do you want to get more specific? Our map
is visual, and we place no tresspassing signs. Most other mammals
urinate to mark territory. And so there clearly are functional
differences at narrower scopes.
