> A better explanation, which might appeal to computer programmers [...] a powerful new DSL for describing complex body shapes: the Hox genes In a similar vein, a talk some years back, IIRC, suggested step-function-like expansions of miRNA repertoires (conserved regulatory small RNA families) at important phylogenetic tree branchings, was fruitfully viewed as "ok, now we have the knobs and dials to take on a new level of metabolic and morphological system complexity". Sort of vaguely like watching an SPA website's js bundle expand - "ok, looks like it's picked up a reactive programming library, oh, and now it has components, ...". I wondered if it might fruitfully be used as a theme, to rearrange how the phylogenetic tree is taught to kids. Perhaps gaining a clarity from lower-cardinality deep structure, that's less accessible in sea-of-features detail and stamp collecting.
