The origin of new mutants only as chance may be more an assertion than fact. 
Further, if processes such as biased gene conversion are evolutionarily 
signficant (as suggested by some molecular geneticists) then the spread
and establishment of such mutants does not require natural selection,
and is certainly not random.
