Some ineresting info coming up.  Seems the primary cause is injuries to,
or abberations of the mantle, at least so far as patterns and pigments
are concerned.  Has any anyone, however, done any biochemical or genetic
work, to discover whether melanism is caused by a mutation (Why do only
a small minority of any given population ever become melanistic???), and
what the biochemistry of the phenomenon is?  Also, i have heard nothing
but  a vast silence regarding the **precise** cause of rostratism, and
how it is linked to melanism.
 
It's snowing here.  Merry Christmas!
-Ross.
