Re: Clumsy label
Are viruses a form of life according to biologists or not?

I have never been very clear on this.

And I understand that the discovery of "large" viuses has confused the issue by suggesting a genetic history that may mean what we call viruses were not always so parasitic and may warrant their own branch on the evolutionary tree.

Or something like that.......

Sorry for my vagueness. I am looking for info from those that know rather than a debate about a topic I am wholly ignorant in.

Re: Life?
To be honest I was primarily asking because I don't know the answer to my own questions.

I wanted to know where the boundary imposed by your definition lay in terms I could understand.

But if it made you think more about the definition in question then I guess that is a good thing.
