User:Arkuat/Taxonomy

Please browse the many articles that our Wikipedia has about the various taxa of living organisms!

The sorting order of these lists tries to follow the principle of most-familiar-first. Whenever a list of obscure taxa needs to be sorted, we try to follow the principle of listing the taxa in order of first published description. This last principle can be tricky too, and since we don't have access to all the relevant information about dates of first public description, many of the sublists in this outline are in semirandom order.

The names of phyla and divisions (equivalent taxonomical levels reflecting differences of nomenclature between zoologists and botanists) are in bold text.

Domain Eucarya
The eukaryote regna are sorted this way to reflect the idea that animals and fungi are closely related to the opisthokont group of protists, and the plants are related to another group of protists. Protists are the paraphyletic subtaxon of eukaryotes. So yes, plants are much more familiar than protists and were discovered earlier.
