AW: Moa-Tinamou Clade Found Within Ratites
Did anyone count how often paleognath phylogeny was "resolved" yet?
And do Baker et al (2014) address the concerns of Smith et al (2013)
Kimball et al (2013?)
and Yuri et al (2013)
regarding the need to test any
"new phylogenomic sequences from 1,448 nuclear DNA loci totalling almost one
million base pairs"
(and RGCs just as well) on whether they actually retain phylogenetic signal?
An additional question: considering we have no problems getting the artificial
(Paleognaths,(Passerines,other neognaths)) or
(Paleognaths,(Galloanseres,(Passerines,other Neoaves))) quite robustly
supported - how can we be sure (Ostrich,other paleognaths) is not artificial?

Genomic Support for a Moa-Tinamou Clade and Adaptive
Convergence in Flightless Ratites.
Molecular Biology and Evolution (advance online
One of the most startling discoveries in avian molecular
is that the volant tinamous are embedded in the flightless
but this topology remains controversial because recent
phylogenies place tinamous as the closest relative of a
ratite clade. Here, we integrate new phylogenomic sequences

extinct little bush moa, Chilean tinamou and emu with
sequences from ostrich, elegant crested tinamou, four
the green anole. Phylogenetic analysis using standard
models and heterogeneous models robust to common topological
recovered compelling support for ratite paraphyly with the
moa closest to tinamous within ratites. Ratite paraphyly was
corroborated by eight independent CR1 retroposon insertions.
