JE:-
The only possible way that the mean fitness of an organism can be maximized by not contradicting Fisher's dictate of what is and what is not heritable and therefore selectable within nature, is to assume that the mean fitness of one organism is just the mean fitness of each and every genomic gene within one organism. This requires initially that an independent fitness empirically exists for each gene. These must be added to form one organism total which must then be divided by the number of genes. The problem with all that is that within nature not even the fitness of the smallest trait, i.e. one coded by just to loci has never been _empirically_ demonstrated to be the addition of the fitnesses of each of just two genes that code for it let alone ALL the genes that constitute one organism. Neo Darwinism became (after Carol and Van Valen's usage of Carol re: his Red Queen hypothesis)a Mad Hatter's Tea Party after Fisher's dictate because even if the mathematics worked the evolutionary biology and the refutability of evolutionary theory became reduced to an absurdity. JE:- Yes but can't you see that because additive gene fitnesses remain heritable via Fisher, fitness independent genes were being assumed to provide Fisher's maximised organism mean fitness so that selection had to be operating FIRSTLY at a supposed _independent_ gene level between independent in fitness genes and not at the empirically based Darwinian organism level. Fisher's dictate of what is and what is not heritable simply deleted all gene fitness epistasis when in nature, all gene fitnesses remain epistatic. Fisher forced the CRITICAL first act of selection to operate at a mythical gene level and not the empirically based Darwinian fertile organism level. In reality the very first act of selection remains at the Darwinian level and NOT Fisher's gene level. Below the fertile form level all acts of selection remain fitness DEPENDENT acts which are entirely dependent on the single Darwinian level so they are all just SUB SELECTIVE EVENTS and not SELECTIVE events. Fisher confounded sub selective events with selective events. Subsequently this produced Haldane's false Dilemma and Hamilton's false explanation of evolution organism fitness altruism derailing the evolution sociality within nature. The confounding of selective events with sub selective events became known as the "multi level approach". Because of the original misuse of Fisher's dictate all the multi level approach became good for was evading refutation via ad hoc hopping to some other level after the level you were employing at the time became refuted. JE:- It was never just a "simplification" employed these views it was a empirically based Darwinian fitness *OVERSIMPLIFICATION*. In one stroke Hamilton's inability to more exactly understand what empirically based Darwinian fitness actually is and his inability to understand that if you oversimplify this you reduce evolutionary theory to just a heuristic exercise, reduced evolutionary theory to a non refutable proposition. There it has remained ever since. JE:- What Hamilton appears to be suggesting is: inclusive fitness was only meant to be a model engineered to help understand fitness at the Darwinian individual level, i.e. it was never meant TO REPLACE IT. It appears that dunderheaded mathematicians misused Hamilton's model to replace organism fitness. Where has it all this nonsense ended up? NAS's oxymoron: a NON centric model fitness floating about in a Mad Hatter mathematical aether created to get rid of IBD relatedness which remains the only allocated fitness lifeline that Hamilton el al heuristic relatedness, had. JE:- And CRUDE it remains because all gene fitness epistasis remains deleted to this very day. When you included it Hamilton's reasoning fails because the rule now becomes: (r^e)^b where e (epistasis) = (minimally) 2 and not just 1. This forces the cost of proxy reproduction to increase exponentially so that just a few alleles coding for just the one trait (let alone all the alleles coding for one maximised organism Fitness as Fisher wished) makes inclusive fitness non affordable. I find it amazing that NAS (along with most of the other Neo Darwinians that post here) simply evade this argument. JE:- Firstly, note that Hamilton has absolutely no idea of what an empirically based Darwinian fitness is. All he knows and all the Neo Darwinian establishment appears to want to know is Herbert Spencer's hopeless tautology which is not a valid theory of anything. Secondly, the argument "..it is to the benefit of the gene G; and this will be the case if the average net result of the behavior is to add to the gene pool a handful of genes containing G in higher concentration than does the gene pool itself" CANNOT prove organism fitness altruism on behalf of his only proactive actor yet Hamiton's evolution of altruism argument (the only reason he created this rationale) rests on just this one supposition. JE:- No apology required because Hamilton's argument remains _hopelessly_ polycentric and therefore entirely non refutable. Why don't you ask the Pope of Neo Darwinism?
