discussion

David and Nancy, I noticed you got started on this article. What do you make of the assertion in the opening section that viruses do not have a cell membrane? This seems a bit misleading since they do have a membrane when outside the cellular environment. It may also be a circular argument since if they are not defined as cells they of course they cannot have a cell membrane. I have to admit i am in the camp that viruses are most certainly alive but represent a highly derived life form that is simplicity at its most elegant.
