TINKERING FOR A BILLION YEARS. “Many of the regulatory genes in butterflies, giraffes and squid, for example, are similar, having been inherited from their last common ancestor, the protostome–deuterostome ancestor, which lived at least half a billion years ago. Thus the striking changes in body plans have been accompanied by relatively modest tinkering with the machinery of early development of that long-extinct precursor.”
