style='font-size:13.5pt;font-family:Arial; color:black'>: That the current Gruiformes is a polyphyletic grouping has been suspected for most of this century. See Sibley &amp; Ahlquist (1990) for a review. Here's what we say with respect to inclusion of the Cariamidae at the Note under Gruiformes:</span><span style='font-size:13.5pt;font-family:Times; mso-bidi-font-family:"Times New Roman";color:black'><o:p></o:p></span></p> <p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; margin-left:.25in'><span style='font-size:13.5pt;mso-ascii-font-family:Cambria; mso-hansi-font-family:Cambria;mso-bidi-font-family:Arial;color:black'>&quot;The extreme morphological heterogeneity among the families of the Gruiformes has always made the monophyly of this order suspicious (see Cracraft 1981, Sibley &amp; Ahlquist 1990). Although Sibley &amp; Ahlquist's DNA-DNA hybridization data provided support for a monophyletic Gruiformes, subsequent genetic data have failed to do so. Although Fain &amp; Houde's (2004), Ericson et al.'s (2006), and Fain et al.'s (2007) genetic data strongly support the monophyly of a core group of gruiform families that consists of the Gruidae, Aramidae, Psophiidae, Rallidae, and Heliornithidae, support for inclusion of other traditional gruiform families is weak or nonexistent. Concerning families found in South America, Fain &amp; Houde (2004) and Ericson et al. (2006) found that the Eurypygidae does not belong in the Gruiformes but rather in a major, separate radiation of the Neoaves, with the Rhynochetidae the likely sister family of the Eurypygidae (see also Houde et al. 1997, Livezey 1998, Cracraft et al. 2004), and that the Cariamidae (and also the Old World Otididae) is in an altogether different branch of the Neoaves than are the true Gruiformes (see also Livezey &amp; Zusi 2001, Mayr &amp; Clarke 2003, Ericson et al. 2006). Proposal needed to remove these from Gruiformes &lt;wait for at least one more dataset from TOL/Early Bird projects?&gt; . Recent morphological data (Livezey &amp; Zusi 2007) support the monophyly of the traditional Gruiformes except that the Rallidae (represented only by Porphyrula) and Heliornithidae (and Old World Turnicidae and Mesitornithidae) might belong in the Charadriiformes.&quot;</span><span style='font-size:13.5pt;mso-ascii-font-family: Cambria;mso-hansi-font-family:Cambria;mso-bidi-font-family:"Times New Roman"; color:black'><o:p></o:p></span></p> <p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:13.5pt;font-family:Arial;color:black'>The studies that have supported placement of the Cariamidae in the Gruiformes were Cracraft's (1982) analysis of osteological characters, Sibley &amp; Ahlquist's (1990) DNA-DNA hybridization study, and Livezey &amp; Zusi's (2007) analysis of morphological characters.</span><span style='font-size:13.5pt;font-family:Times;mso-bidi-font-family: "Times New Roman";color:black'><o:p></o:p></span></p> <p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:13.5pt;font-family:Arial;color:black'>However, four independent data sets now show that the Seriemas are not members of the core gruiforms. Mayr &amp; Clarke (2003), using morphological characters, found no evidence that the Cariamidae were even close to the core Gruiformes. Cracraft et al. (2004), using about 1150 bps of the nuclear gene RAG-2 found no support for placement of the seriemas in the core gruiforms (Rallidae, Heliornithidae, Gruidae, Aramidae, Psophiidae). Fain and Houde (2004), using abut 1250 bps of the nuclear gene beta-fibrinogen, also found no support for including the Cariamidae in the core Gruiformes (same 5 families as above, the monophyly of which subsequently reaffirmed by Fain et al. 2007). Ericson et al. (2006), using ca. 5000 bp from 5 different gene regions, found that the Cariamidae were distant from the core Gruiformes (in fact, coming out near Falconidae and Psittaciformes).</span><span style='font-size:13.5pt;font-family:Times; mso-bidi-font-family:"Times New Roman";color:black'><o:p></o:p></span></p> <p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:13.5pt;font-family:Arial;color:black'>Therefore, the evidence for inclusion of Cariamidae rests on historical momentum, some morphological analyses that are clearly unable to ferret out convergence (e.g., Livezey &amp; Zusi 2007 also still firmly support a sister relationship between Gaviiformes and Podicipediformes), and a genetic analysis that has been attacked repeatedly (Sibley-Ahlquist brand of DNA-DNA hybridization). For our classification to reflect current phylogenetic data, I think we need to extricate Cariamidae [<i>and Eurypygidae - that will be a separate proposal</i>] from Gruiformes in that it is highly likely that continued placement there violates the primary principle of classification, namely monophyly of taxa (above species level). Therefore, in my opinion, we have to place it as an Incertae Sedis family or place it in its own order.</span><span style='font-size:13.5pt;font-family:Times; mso-bidi-font-family:"Times New Roman";color:black'><o:p></o:p></span></p> <p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:13.5pt;font-family:Arial;color:black'>I might favor the former except that Cariamiformes has been used in the past.
