      Which evidence is this? The fact that a lot of yammerheads SAY it
      won't work is not actually evidence, you know.

      Been there, seen it, done it. Don't see any evidence to support the
      claim that the NEW genetic variation being seen due to mutation will
      not cause isolated populations to diverge, as they mathematically
      must do unless some actual force prevents it.

      Yes you are. And you are doing it either because you were sold a
      bill of goods by creationists more interested in sophistry than in
      science or because you wish to peddle such a bill of goods.

      I would strongly suggest that you get your biology from science
      sources, not religious heretics with an agenda.

        What does it matter why they would consider it? It's a hypothesis,
        consider it.

        If I get up tomorrow and find a car wrapped around the tree in my
        front yard, which is the logical response:

        1. That's a car that has been smashed into a tree and no longer

        2. That looks like a smashed car, but it might have been built that
        way and serve some other purpose.

        We have a defective vitamin C gene. Worse, we have exactly the same
        defective vitamin C gene that chimps have. Trying to pretend that it
        might be something else is silly.

        \The IDiot will solemnly inform you that chimps and humans are separately
        and similarly designed with the defective gene in both.

        But if you don't like the vitamin C gene, let's move to the growth
        regulator gene that has a transposon stuck in it. Not only can we
        identify it's original purpose, but we can tell you what happened to
        change it and what would happen were it somehow reactivated. This
        isn't rocket science.

        \It must be, IDiots can't figure it out.

        That acestor wouldn't have a non-functional gene just waiting for one
        change to turn it into a vitamin C gene. Off happens fast, but
        development works in stages.

        \Redevelopment of a disabled gene can take a highly roundabout route.
        Take the gastrointestinal torsion of the Gastropoda. Apparently a point
        mutation caused one muscle to fail, twisting the intestinal tract to
        empty just above the head. The Opisthobranchia have reverted to the
        normal molluscan condition, but through a complicated process.
