Should I use Phylocode?
There is nothing to force anyone to use or not use the Phylocode (PC), or the established ICZN code (the Code). However, and it is a big however, the ICZN Code is effectively universally used by zoologists and required by editors (where they are well enough informed to know what the rules are) because it has been the standard for a long time (essentially 100+ years for the Code in its various versions and 250 years for Linnaean binominal names on which it is based) and is the product of international agreement among scientists (who worked together despite world wars, etc).
