Yes, Emilio, i do live in the only known biosphere in the universe, and i do know folks are doing
all sorts of things with their genetic sequencing work - but can you come up with a good example of
a taxa or taxonomic group which has been "reworked" in light of genetic findings - and has this (and
similar revisions) been widely accepted by the rest of Malacological community??
Cheerios,
Ross.
