Contentious relationships in phylogenomic studies can be driven by a handful of genes.
Nature Ecology & Evolution 1, Article number: 0126 (2017)
74 percent of the shared genes favor the hypothesis that crocodiles and turtles are sister lineages while birds are close cousins.
..., Nick Gardner asks me to forward the following:
The paper does NOT say that 74% of shared genes support a turtle+crocodile hypothesis. It says the OPPOSITE.
On p. 6, it explicitly says "For example, similar to the well-established branch associated with the monophyly of amniotes on the vertebrate phylogeny that we used as a control (Figs 2–4), examination of the evolutionary placement of turtles (Table 1 and Figs 2–4) showed very strong support for the hypothesis that turtles are the sister group to archosaurs (birds + crocodiles). Specifically, the ΔGLS values of 74% (3,466 out of 4,682) of the genes in the data matrix favour this hypothesis over the second best alternative (turtles as sister group to crocodiles) (Supplementary Fig. 2a); the same is true for ΔSLS values (88% or 1,588,738 out of 1,806,035 sites favour turtles as the sister group to archosaurs rather than to just crocodiles; Supplementary Fig. 3b)."
