We have no basis for disagreement. Hybridization has played a major role in 
the evolution of many plants and animals. Linnaeus' early work however did 
not separate "natural self-replicating populations" from man-induced 
non-stable genomes that were cultivars created by humans for our own pleasure 
(e.g., Canis familiaris). I think you would agree that only the natural 
populations fulfill what systematists consider to be "species".
