It is also highly likely that there was at least one, and probably several, lineages of Charadriiformes, that penguins were about to split from their closest relatives or had already done so, and that if the Metaves are a valid group they would presumably have been distinct too.
Tamén é moi probable que houbese polo menos unha, e probablemente varias, liñaxes de Charadriiformes, e que os pingüíns estivesen a punto de separarse dos seus parentes máis próximos se é que non o fixeran xa, e que se as Metaves son un grupo válido, presumiblemente xa se terían separado.
