I'd dearly love to know what are the criterion for information.

How many times do I have to post the same defintion? Information is
the degree to which one variable of a system depends on or is
constrained by another.

Your definition does not seem useful. I've asked for another application of
information where you can demonstrate the utility of this definition. I'll
ask again here.


Do the remnants of a complex gene that once coded for a complex
protein have more information than the simplest gene? The former would
be irrelevant to biological processes of the life form but would
contain more information for the scientist who studies that genome.

Vestigial genes are nonadaptive, so there's little to no relevant
information.

And what happens when such a gene does get expressed again and actually
incurs some effect on fitness?

Reposting something else as well: A series of alterations that
conserves a gene's functionality does not add or subtract information.

We're not talking about an alteration, we're talking about a gene being
re-expressed.

Information is the degree to which one variable of a system depends on
or is constrained by another. Duplicating a variable does not increase
that association. A series of alterations that conserves a gene's
functionality does not add or subtract information.

How does this work for polyploidy speciation?

That depends on what advantage to fitness the polyploidy brings.

Why should it matter whether it's advantageous or disadvantageous.

I have a copy of Henry V. Does it contain more information if I open it, or
leave it closed?
