Under any and all conditions favourable variations are preserved,  and

Which is banal concept extended today with: Genetic mutations are
either harmful, neutral or positive. But everything that is in
existence is either Pos, neg or neutral, it is a generalized truism
that can be extended to anything , any concept in any domain
spiritual , metaphysical or physical.

Really? Vanilla  Icecream is either positive, negative or neutral? And
what would that even mean?

What does it mean to say a mutation is pos, neg or neutral in terms of
the differential equations of this paperhttp://www.uic.edu/classes/phys/phys450/MARKO/N013.html.

It doesn't mean anything in regards to that paper. Why do you pick
random papers and cite them, while claiming that *we do not make
sense? that paper is on protein folding, not differential
reproduction.

If a genetic mutation is "beneficial" how was this beneficiality
measured other than noting the organism propagated.

It didn't merely propagate; it propagated more than others in its
genepool. It was measured by *counting. Do you really think that you
can hold an intelligent and informed opinion on science when you don't
know what counting is?


The words pos, neg, neutral don't have a single true meaning, in the
context of biophysics it means what? In the context of
1 ) "positive mutations" + "natural selection"
2 ) "negative mutations" + "natural selection"
3 ) "neutral mutations" + "natural selection"
what does it mean.

It means they have more, the same, or fewer offspring, respectively.

As noshell pointed out these are word terms where is the math? This
paperhttp://www.uic.edu/classes/phys/phys450/MARKO/N013.htmldon'tt
contain these weasel words.

You think more, same, and fewer are weasel words? You complain that
there is no math. Why not look up "evolutionary mathematics" +biology
in a search engine?

From the first hit in Advanced Google at

(Description of the book "Evolutionary Dynamics")
"At a time of unprecedented expansion in the life sciences, evolution
is the one theory that transcends all of biology. Any observation of a
living system must ultimately be interpreted in the context of its
evolution. Evolutionary change is the consequence of mutation and
natural selection, which are two concepts that can be described by
mathematical equations. "Evolutionary Dynamics" is concerned with
these equations of life. In this book, Martin Nowak draws on the
languages of biology and mathematics to outline the mathematical
principles according to which life evolves. His work introduces
readers to the powerful yet simple laws that govern the evolution of
living systems, no matter how complicated they might seem. Evolution
has become a mathematical theory, Nowak suggests, and any idea of an
evolutionary process or mechanism should be studied in the context of
the mathematical equations of evolutionary dynamics. His book presents
a range of analytical tools that can be used to this end: fitness
landscapes, mutation matrices, genomic sequence space, random drift,
quasispecies, replicators, the Prisoner's Dilemma, games in finite and
infinite populations, evolutionary graph theory, games on grids,
evolutionary kaleidoscopes, fractals, and spatial chaos. Nowak then
shows how evolutionary dynamics applies to critical real-world
problems, including the progression of viral diseases such as AIDS,
the virulence of infectious agents, the unpredictable mutations that
lead to cancer, the evolution of altruism, and even the evolution of
human language. His book makes a clear and compelling case for
understanding every living system - and everything that arises as a
consequence of living systems - in terms of evolutionary dynamics."

There's plenty of math in evolutionary science. If you can post on
usenet, you can use a search engine.
