Opinions on multiple sequence alignment, and an empirical comparison of repeatability and accuracy between POY and structural alignment.

An extensive literature, special symposia, and even a formal organization (International Society for Phylogenetic Nomenclature) have been devoted to various other taxonomic proposals some of which seem far more radical and/or less utilitarian than the timeclip proposal advanced here. Thus, we now invite open discussion on the temporal-banding strategy and on timeclip-like tactics that could greatly enrich existing taxonomies while still maintaining established Linnaean traditions and nomenclatures.
