Predictability is ultimately predicated upon the knowledge of the one who assesses a given cause and effect. As such it is subjective by definition and of little, if any, scientific value. Any law of unpredictablility must also necessarily have limits, because physical reality entails an ample supply of predictable phenomena. Lastly, if a law of unpredictability were given full sway by science, then such phenomenon as virgin births could hardly be discounted as "unscientific" in nature.
which is why scientific predictions are expressed in probabilities, not as certainties
moreover, you are engaging in erroneous misapplication.
the law of unpredictable consequences is NOT a general law of complete unpredictability, nor is it some occult spell which renders the physically impossible merely improbable.
on another note, virgin birth is not ruled out by biology. look into parthenogenesis, for starters.
on yet another note: thanks for bringing up an issue which is so thoroughly irrelevant to the topic.
and so ends my willingness to attempt to correct your apparently inexhaustable fund of serial errata tonight
