Also, selection itself is a very non-random factor, invalidating attempts
to disprove "evolution" by showing that random processes do not create a
specific sequence rapidly. However, there is randomness at higher levels
than the genes. For morphological factors not too tightly controlled by
the environment or intrinsic factors, variation over time may be
mathematically random. In muricid gastropods in the western Atlantic, the
oldest ones are small and lack spines. Today, there are big and spiny
ones. However, there are still little non-spiny ones. An increase in the
range of variation is all that is needed to explain this, because the
number of spines cannot go below zero and the original size was relatively
small.

If He is sovereign over the outcome of casting lots, the long-range
weather, and other random or chaotic (in the mathematical sense) events,
then it seems that randomness does not constrain Him. Whether there is a
pattern yet hidden to us, or whether He simply directly chooses the outcome
is moot.
