Hi,
I agree wholeheartedly, we are still far from knowing the boundaries of a
species. Charles Darwin wrote, "... I look at the term species as one
arbitrarily given, for the sake of convenience, to a set of individuals closely
resembling each other, and that it does not essentially differ from the term variety,
which is given to less distinct and more fluctuating forms." Darwin was happy
to acknowledge that defining a species was not always possible. He wrote,
"In short, we shall have to treat species in the same manner as those
naturalists treat genera, who admit that genera are merely artificial combinations made
for convenience."
Darwin did not argue that species did not exist, but he did argue that they
were darn difficult to precisely define in all cases.
