If you move many of the spp/forms of Tanganyikan Chicklets around the
lake, you _will_ see hybridization. There the main reason for many of the
species that're closely related not hybridizing is that there are either
_geographical_, behavioral, or structural differences that prevent it. This
is the same w/ bows. Wipe the dust off of your ecology texts, my friends,
and re-read the part about speciation and competition, and you will see
that much of your logic on this "There won't be any bows hybridizing
here" stuff is BS. They can do this is the wild, given proper conditions
(and this is NOT an unlikely thing, folks) and they will if given the
"opportunity." Please don't forget that geographic isolation is one of
the things that keeps species separate in the wild. Remove those
boundaries and you can get croos-breeding (or competition, which may well
be the biggest threat, as this is what wipes out a spp from it's native
environs).
You want proof of natural events of this? Do some reading up on marine
angels. This stuff goes on in them, and we haven't even begun to move
them around the globe and screw them up yet. :-)
Lecture's over.... for now.
