The conflict between evolution and deism is simply that it renders the idea of a creator god redundant, and moreover since human consciousness has evolved, raises the question of where the deity evolved from, but all that could indeed be considered a metaphysical argument. -The real conflict between evolution and chistianity lies in the Adam and Eve story - the Y-chromosome Adam and the Mitochondrial Eve lived ages apart. Francis Collins and his colleagues at BioLogos get round this by postulating that a pair of humans, Homo Divinis, were somehow 'ensouled' by the deity, though when this happened is still to be determined, and can only be reconciled with the Genesis story with a good deal of poetic licence.
