Dear Andy;-
    This be what I gone do: I'd like to use your well-thoughtout
letter in the March issue of EPINET. I will probably trim it a bit,
but nothing to change meanings or emphasis.
    I got one more little question: Although all members of a species
"CAN" theoretically inter-breed. In many case they don't. Although
members of the same species, I have never heard of a Great Dane being
mated with a Pekinese. I also doubt if the Pygmies of the Ituri rain-
forest have ever mated with Watusi or Lithuanians. So the question I
have is: Over great lengths of time, does such separation evolve into
further speciation? Are we just talking likelihood?
