agreed that the compact genomes of viruses probably survived through
natural selection. but can one be absolutely sure of that ?
and even then, they had to originate somewhere - and what we see now
are the ones which survived through natural selection. 
so where were the origins anyway ? and what's the probability that
random pieces of dna got selected to be viruses - pretty low, i'd say,
considering that there even exists virus(es) with both the strands
completely coding (all products essential for the virus) !
