@Fil Albuquerque,
Quote: I want to ask you whether you make a distinction between true randomness or pseudo randomness and which one is the one you place your bet.
Please explain what you mean by "true v pseudo" randomness?
Most of the genomic complement seems to be random generation of new forms by several means. (Some nat selection of a molecule occurs but its hard to express how this happens). Since the rates of mutations occur as a function of the umber of organisms and rates of reproduction, Almost any combination of alleles can be envisioned. (Sexual selection, genetic drift et). DArwin actually said thi in hi second edition of the "Origin" --all while having not a clue about genes or DNA or anything biomolecular.
Nevertheless, once the genome EXPRESSES itself as a (several) pronged means of affecting subsequent genotypes, it seems to have limited the number of subsequent expressions.
SO, natural selection, which explains how the organism interacts its "pallette" of genomic expressions with the environment, actually FOCUSES subsequent allowable evolving genotypes for that particular organism.
In otherwords , once an organism evolves from a "mother species", it is self limited in the number of expressions the subsequent daughters may display.
eg, once a wing first wvolved (probably as a random mutation)within the HOX sequence in an arthropods thorax genes, there are a limited number of expressions that can show up over time and these seem to be mostly controlled by adaptational mechanics.
