As for the Joestar bloodline part, that seems fairly self-evident. DIO, Joseph, Jotaro, Holly and Josuke all got Stands/fell ill at the same time. At the time DIO shot himself with an arrow.
The souls part. I get the whole Dio/Jonathan thing, I mentioned that in my above post. I don't buy the "infect the souls" idea because the whole virus shebang sounds too biological. However, I do concede that the biological theory can't explain why Joseph got a stand after birth.

@DBZ: The meteorite metal contains a virus which infects people. Once it infects you, you either develop immunity or die. "Immunity" seem to come with Stand Powers. That's what's happening right now. I don't know about this "Viral Evolution" thing. Maybe the virus DNA integrates into your own, and either your body rejects it and you die.. or your body is able to accept it and you then gain special powers. Something like that.
