P. unicornis is a sister species to Mitu tuberosum?
[edit]Mitochondrial analysis conducted in 2004 suggests that P. unicornis is a sister species to Mitu tuberosum, while the other Pauxi species, P. pauxi, is sister to the combined Mitu and P. unicornis clade. This means the genus Pauxi is not monophyletic but paraphyletic, and to resolve this parsimoniously the genus Pauxi should be sunk into synonymy with Mitu.[1] The paraphyly of Pauxi could be due to incomplete lineage sorting, where a gene tree is inconsistent with its species tree, however this phenomenon should be less prevalent in deep phylogenetic splits (i.e. between genera). Because of this, Pereira et al. conclude incomplete lineage sorting is unlikely to account for the paraphyletic Pauxi genera because, according to their own analysis, Mitu and Pauxi diverged approximately 6.5mya.[1]
I tried to find these statements in the cited paper, but didn't find them. It appears the P. unicornis wasn't part of the study at all. Please refer me to the exact place in the paper that corresponds with this statement or cite another source, please. Sir Shurf (talk) 16:34, 5 November 2019 (UTC)
