Fitness (often denoted w in population genetics models) is a central
concept in evolutionary theory.
Fitness isn't a concept but a word. This word is used by individuals
to encode their specific concept for us to decode.


Please provide examples of concepts that are not represented by words. And
explain just how the two got separated.

It describes the capability of an individual of certain genotype to
reproduce, and usually is equal to the proportion of >the individual's genes
in all the genes of the next generation.

The abstract authority Mr.Fitness didn't describe anything - who is
this person that has done the actual description of what ?


That would be Mrs Dictionary, or if you want the detail Mr Scientist
consulting with Ms Lexicographer.

If differences in individual genotypes affect fitness, then the frequencies
of the genotypes will change over >generations; the genotypes with higher
fitness become more common. This process is called natural selection...."

Who has defined what is a genotype? Other than noting that "genotypes"
became more common how was their fitness measured. And who has called
this process "natural selection" ? Darwin didn't know about genes is
the author
referring to him.


Gosh we seem to have been here before, Mr Backspace has a perpetual calendar
that chimes at the end of each month reminding him to post the same word game
as last month and the month before.
