Isn't this just the central dogma? Just because we call it a "dogma" doesn't mean there's any idolatry or superstition here. — Srap Tasmaner
It's the dogma, but it's what Dawkins draws from the dogma - what he thinks it entails - that's quite literally unscientific. Actually theological. To put the problem as starkly as can be: genes don't exist. Or, less provocatively, the individuation of genes can only be processual, not structural. Here's Evelyn Fox Keller:
"One gene can be employed to make many different proteins, and indeed the expression “one gene–many proteins” has become fairly common in the literature. The problem with this formulation is that the gene has lost a good deal of both its specificity and its agency. Which protein should a gene make, and under what circumstances? And how does it choose? In fact, it doesn’t. Responsibility for this decision lies elsewhere, in the complex regulatory dynamics of the cell as a whole. It is from these regulatory dynamics, and not from the gene itself, that the signal (or signals) determining the specific pattern in which the final transcript is to be formed actually comes" (
The Century of the Gene)
And once you take these environmental dynamics into account, the dogma loses much of it's explanatory power. In fact Derrida - who, hey, you invoked - is pretty bloody
apropos here. The Derridian geneticist says: there is no outside the cellular environment (or, more accurately, the
developmental system).
Il n'y a pas de hors environnement cellulaire. Fox Keller again:
"Fifteen years ago, the historian and philosopher of biology Richard Burian observed, “There is a fact of the matter about the structure of DNA, but there is no single fact of the matter about what the gene is.” In the interim, things have only gotten worse ... As Peter Portin observes, “Our knowledge of the structure and function of the genetic material has outgrown the terminology traditionally used to describe it. It is arguable that the old term gene, essential at an earlier stage of the analysis, is no longer useful.” William Gelbart, working at the forefront of molecular genetics, concurs in suggesting that the gene might be “a concept past its time.” “Unlike chromosomes,” Gelbart writes, “genes are not physical objects but are merely concepts that have acquired a great deal of historic baggage over the past decades.”
I know this is just a bunch of quotes, but in lieu of actually detailing the complexities of gene expression, the point is that the problem with Dawkins lies at the level of the individuation of gene, let alone all the rubbish about 'it' being 'selfish'.
