Most bacteriophages lasck introns, but introns have been found in the DNA viruses of eukaryotes.?

The RNA viruses of eukaryotes, however, lack introns.

What do these findings suggest about the origin of viruses?(consider what evolved first:prokaryotes or eukaryotes.)

Eucaryotes evolved after procaryotes. Their features and organization is much more complex %26 organized then the latter, %26 are more versatile. Also, error correction is better.

Most bactreria do not have introns. Some virus have introns but they are most probably recently derived from host DNA. A similar phenomenon to viral transduction. (since virus are compact and do not have spare room in their capsids, those

introns will disappear shortly, in geologic time. Host RNA have introns cut out when they are transcribed from nuclear DNA to messenger RNA. Therefor an RNA virus picks up RNA, (%26 not DNA, excepting retro viruses which are a small % of RNA virus species).
