the gene will be generated (due to a very common mutation?) then the
older organisms might not be ancestors. If the probability is moderate to
low (say 1 in 10^300) then chances are the origin took place only once and
was passed on. Thus it is reasonable to infer the earlier organism is an
ancestor of the later organism. (Please note early versus later requires
fossil record of some sort, which is part of what Don was trying to point

The entire field is based on the concept that these codings are very
unlikely to be produced more than once. In other words, the probability is
deemed to be too low. It is _all_ an inference from probability.

Another aspect is the idea that the bad version has the good version as a
precursor. Maybe that is a faulty hypothesis. I'd have to ask whats the
pathway? Is there a reverse pathway? Are we sure the bad didn't come first,
producing the good due to some event? Can we rule that out?

Things don't seem so terribly obvious to me.
