clarity[edit]

This introductory sentence is sure to scare off almost anyone trying to learn about laurasiatherians:

"Laurasiatheria is a clade of rank cohort or magnorder (although it is ranked super-order in traditional Linnaean taxonomy), within the Placentalia (living) or Eutheria (Placentals and their extinct ancestors) infraclass of mammals."

If a taxon is assigned to different ranks by different authors, we can discuss that later in the taxonomy section. It's not an essential aspect of the taxon and we there's no need to confuse readers, who are most likely interested in the characteristics and membership of the group.

I am under the impression that the term was older than genetic confirmation of the clade. —Preceding unsigned comment added by 94.65.82.56 (talk) 10:02, 14 May 2010 (UTC)

Insectivora removed[edit]

I removed the polyphyletic order Insectivora from the "taxobox" since it is replaced by Erinaceomorpha and Soricomorpha Kolorado (talk) 13:25, 19 February 2011 (UTC)

Zhou et al[edit]

I just did a quick update to Pegasoferae after I noticed an article in PubMed by Zhou et al.: Phylogenomic analysis resolves the interordinal relationships and rapid diversification of the Laurasiatherian mammals (Advance Access; published online 07 September 2011) which states "Pegasoferae (Perissodactyla + Carnivora + Pholidota + Chiroptera) does not appear to be a natural group." This apparently is one of several genetic studies since Pegasoferae was proposed that has failed to support it, so I think that we need to deprecate its usage here. -- Limulus (talk) 10:56, 3 October 2011 (UTC)

Clarity in sentence on the origin of the name[edit]

I am an infrequent wikipedia editor so not sure this comment belongs in Talk but the sentence that begins "The name comes from the theory that these mammals evolved on the supercontinent of Laurasia..." can give the impression that all the modern orders (or perhaps even that all the modern species) in this clade evolved on that continent whereas what I believe to be true is that the common ancestor of all these orders (and likely many of the subsequent descendent groups) evolved on that continent but that some or all of the orders, and definitely some of the lower taxa, evolved later after groups had moved to other regions of the Earth and in many cases well after Laurasia had split apart. However, this is not my field and do I feel confident that this is the view of those within the field so I am reluctant to edit the article directly. (But I do want to know the answer so I am hoping placing comments in Talk pages like this gets knowledgeable people to step in and make the elucidating edits ;-))
