If your reverts are NOT intended to avoid a problem then how do you justify them Or did you not read what you were responding to  In any case the point is that if an edit makes an article better or of equal quality we should leave it We do not own this article as individuals  Your response which now seemingly diverts attention to P is silly and again if you are serious then please do not just cripple the article fix it like you imply you would which would mean making a P article That P article should of course link both upwards and downwards within the accepted phylogeny If you refuse to put in the alternative solution then your revert is unjustified by the explanation you have given This is the same as when you previously argued that people could look things up in the E article In the end the article needs a Wikipedia link up to the article concerning the next level I am asking you to do it in whatever way you think works
