On point 2 : well you got me there. Let me be more precise : its not the "natural processes" part that is important, but my point was rather that this type of hybridizing results in the creation of organisms which have not been time tested and weathered the refining pressures of evolution. We have no gaurantees of the probabability of a successful organism - could be, as I said, some fucked up abomination which only exists to plead for death. Quite tragic in my view if this is the outcome.
I just think we'd better not even go there.
