I would take the position that once human beings control "natural selection" manipulation has begun. We are currently manipulating the species, and as our bungled attempts at doing so have eroded the quality of the hatchery fish, their diminished gene pool, manipulated by man, has adversely affected the quality and genetic integrity of the native.

Is cloning possible?? The evidence clearly suggests that it is within the realm of possibility...

Its also possible that if I put one bullet in the chamber of a revolver, give it a good spin...
