  •  Maybe the point is that it isn't a fixed (17+ / 0-)

    person, in the sense that one might find another individual who fits the bill from an even earlier time.

    It's a concept, a title.  A bit like "Patient Zero."  It always refers to an individual of flesh and blood, but it's always possible we'll find someone earlier to give the crown to.

    In other words, we're creating the world from the opposite direction of the Abrahamic traditions, and don't know how the begining turns out yet.  Let there be light, though.

    •  Well, it was *somebody* :) (6+ / 0-)

      The fact that we may not have discovered that individual yet doesn't change the fact that it was one person, somewhen...

      We all understand that freedom isn't free. What Romney and Ryan don't understand is that neither is opportunity. We have to invest in it.

        but a real person, one person. A real person was the first to carry the gene, just like a real person was the first to carry the virus that began the AIDS pandemic in the U.S.  

        It it possible to trace the introduction of AIDS in the US (and it was traced) to a single individual.

        If it is a communicable disease, it came from someone.  With modern DNA research, we know so much more before we even start researching ...

        Meanwhile,we can all be aware and awake enough to prevent the accidental spread of disease through ignorance, and through ignoring/not following the gene to its sourcd..  

        •  Well, that's what I said. (I was responding (0+ / 0-)

          to the questioning of that fact, which I stated in a previous comment.) It was somebody. One person.

          I was in the lab where the African Eve research was done (the PI hated that nickname when the press invented it, but he finally got used to it). People had a hard time with the idea that since we're the result of a bifurcating tree, there has to be a point at which the ancestor is a single individual. Substitute "gene" for "we" and "individual, and you have both the Eve and the Adam stories.

          We all understand that freedom isn't free. What Romney and Ryan don't understand is that neither is opportunity. We have to invest in it.
