The Darwinists will use whatever definition of species that suits their doctrine of the moment. Exactly. The definition of *species* is so loose and fluid and vague as to be meaningless.
They can get back to me when they have finally bread something that is no longer recongnizable as a fruit fly, providing that they can prove they engaged in no fraud to get there.
Indeed. After tens of thousands of generations, which would equal hundreds of thousands of human generations, the lowly fruit fly stubbornly remains the lowly fruit fly though gassed, irradiated, dissected, inbred, cross bred, chemical cock-tailed til dead.
So if a person can't change the fly, change the definitions.
