Dear Van,
	You wrote of the formation of new species by having two species co-
habiting and coming together to form a new species, which you saw on a TV 
show.  This is hybridization--it happens all the time when two plant species
can cross-polinate.  The genetic blueprint of the hybrid does not contain all
the information from the parent species.  Sometimes such hybrids are polyploid
as well as having some information from each parent.  Often these hybrids are
not stable (their offspring may revert to the original species or other hy-
brids).  A good botany text would be able to tell you much more about this
process than I know.
