One of the basic mechanisms in evolution, believed to be the major cause of genetical change is mutation. It generally either occurs under radiative exposure or erroneously when duplicating nucleic acids.
However, there are many common arguments that seriously undermine the role of mutations, by showing how improbable they are, more improbable to be several, harmonious and beneficial.
” The rate of mutations is extremely low, made even lower by biological correctors;
” Lower is the random occurrence of harmonious mutations (in the same gene, coding for the same trait/function);
” And so is the rate of non-occurance of side effects (that might nullifiy the new trait, or create new problems);

Re:
Thanks for the welcoming.
My main point was to show the improbability of the harmony, I believe is essential, between mutations for them to be beneficial in terms of the species survival.
If a mutation, at the structural level, of a hormonal molecule was to make it biologically unrecognisable, there would need to associate a certain, according and completive mutation in its receptor for it to be activatable, another in its transporter for it to be properly conveyed, and so on.
Thus, such needed mutational combinations for an organism to continue, evolve and diverge into species and subspecies equals the mutiplication of infinite improbabilites.
