For all the debate, it is agreed upon that <i>poly</i>phyletic taxa are <i>entirely unacceptable</i>, whereas many (but not all) experts agree that <i>para</i>phyletic grades should <i>sometimes</i> be accepted and subsequently ranked by taxonomic commissions (given secondary loss of otherwise monophyletic derived traits). It's almost like a number line, in that biologists/taxonomists disagree on just how limited the limited circumstances when <i>para</i>phyletic (but never poly) grades are acceptable in formal taxonomy really are. Very few are completely at one extreme or the other. </p><p>Again, though, <i>poly</i>phyletic as opposed to para is never ever acceptable in formal taxonomy. If you were to go back in a time machine to before terrestrial vertebrates evolved (random example), you would find that the now-paraphyletic <a href="/wiki/Fish" title="Fish">Grade Superclass Pisces</a> was monophyletic back then. The same can not be said for a polyphyletic group as these are totally arbitrary (consider the case of <a href="/wiki/Protista" class="mw-redirect" title="Protista">Protista</a>). So, in essence, it must always be the case that a taxon either still is or once was monophyletic. The debate (which the Article already begins to cover) is over precisely how often the latter "once was monophyletic" should satisfy formal taxonomic criteria, and the Article should clarify this nuanced matter. <a href="/wiki/User:The_Mysterious_El_Willstro" title="User:The Mysterious El Willstro">The Mysterious El Willstro</a> (<a href="/wiki/User_talk:The_Mysterious_El_Willstro" title="User talk:The Mysterious El Willstro">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Evolutionary_grade#c-The_Mysterious_El_Willstro-2013-10-18T07:26:00.000Z-Here's_the_deal..." class="ext-discussiontools-init-timestamplink">07:26, 18 October 2013 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-The_Mysterious_El_Willstro-2013-10-18T07:26:00.000Z-Here's_the_deal..."><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-The_Mysterious_El_Willstro-2013-10-18T07:26:00.000Z-Here's_the_deal..."></span> </p> <dl><dd><span data-mw-comment-start="" id="c-Peter_coxhead-2013-10-18T12:51:00.000Z-The_Mysterious_El_Willstro-2013-10-18T07:26:00.000Z"></span>There's actually an additional subtlety.

The source given clearly says that hornworts are the sister of vascular plants. However, more recent research has produced different results: see <a href="/wiki/Bryophyte#Classification_and_phylogeny" title="Bryophyte">Bryophyte#Classification and phylogeny</a> for a more detailed discussion.

Per that article, I understand that each of the four groups (Marchantiophyta (liverworts), Bryophyta (mosses) Anthocerotophyta (hornworts), tracheophytes (vascular plants)) are agreed monophyletic, the only issues are the tree connecting them together.
