Great Regulars: What was missing is now called ­epigenetics,

a concept whose importance can scarcely be overstated. The gene-centric view was that the gene produced a protein that went on to build an organism. In fact, we now know not only that some genes can produce several proteins, but also that this mechanism can be turned on and off by processes of which, not long ago, we knew nothing. The gene, in other words, is not the last word and may not even be the first. It is certainly not in complete control of anything.

The implications are staggering.
