I'll agree.  If there's life on Mars and if we have a common ancestor, DNA
or a variant will likely be there - I think this solar-systemspermia is
close enough to panspermia that I meant it to be covered in my repeated
"panspermia aside" comment.  It would certainly add to the wieght of
panspermia.  Regards, Brett.
