The fact is that 'natural selection' describes a real (but contingent
and relative) process that occurs and can be observed and
mathematically measured in nature. Do you have evidence that it
doesn't occur, cannot be observed, or cannot be mathematically
described?

That depends on where was the mechanism responsible for species
transition defined.

No, it does not.

Natural selection occurs within species (by any definition of
'species') and even within discreet populations (i.e., subsets of
species). It is an observation. It is seen to occur. It is not
dependent on any definition of 'species' or 'species transition' and
is a component of the overall theory of evolution, but it is not
dependent upon the definition of the theory.

.. Note that once the mechanism has been defined you
can then label it natural selection if you so desire.

Natural selection is not *the* mechanism. It is *a* mechanism, one of
several.

... But the label is
independent of any as yet to be stated theory.

Nobody, except perhaps you, said that it was.

... You have not provided
me with any theory, what is your theory?

Theory of what? Natural selection? Evolution? You switch gears so
often in your posts it is difficult to tell what you are referring to.

And telling me that traits becoming more common are favorable and
those that don't are not favorable is true by definition and hence a
tautology and not a theory.

You seem to be confused about the difference between definitions and
theories, again. Any theory or observation can be summarized in such
a way as to create a tautology. That does not invalidate the theory
or the observation. NS has been defined for you several times in
this thread in non-tautological ways.
