It's useful for this discussion. We can use a different word for the
same concept if you prefer.

Your speculation that speciation cannot be explained in terms of mutation
and natural selection is invalid as has been demonstrated numerous times
in
the biological sciences.

Such as where?

You appear to be dancing about the nonsense put
forth by creationists that variability and selection cannot produce new
species.

I'm not responsible for other people's nonsense.

To demonstrate your speculation's validity you're going to have to
amass a hell of a lot of evidence, at least 150 years worth of work by
many
thousands of biologists. None of us on this list will live long enough
for
you to produce any evidence that speciation cannot happen by known
evolutionary mechanisms.

Anyone can disprove speciation if they are allowed their own definition of
species. You are creating definitions of species that you think suit your
arguments from ignorance. Since most biological scientists understand the
species concept you are presenting a fairly silly argument for us to play
with.
Perhaps you should study some biology and come up with a better debating
topic.

What matters here is that what I'm calling "speciation" has to happen
for evolution to proceed to any significant extent, i.e. produce the
present diversity of life. We could use other terminology if you wish.
The process of "chrome yellow" is when there is a break in
reproductive continuity on the course of lineal descent. Chrome yellow
must happen for evolution to proceed to any significant extent yet is
disadvantageous to the individual. How do you reconcile this paradox
of chrome yellow?
