Sorry, no etymologies found.


  • That’s pretty interesting, though it has to be said that the statistical support for turiasaurian monophyly is not overwhelmingly impressive.

  • This "monophyly" hypothesis (figure 4B-1) requires the same number of gene gains or losses as the "paraphyly" hypothesis sustained by our phylogeny (figure 4A), both being thus equally parsimonious.

  • In any case, the possibility of multiple aboriginal cells does not survive into textbook neo-Darwinism, in which universal monophyly (a single Tree of Life, rooted in a common ancestor [cell]) is orthodoxy.

  • You then cited publications where Woese, Doolittle, and others, affirm their faith in the monophyly of Eukarya, Metazoa, chimps and humans, whatever.

  • But not species, unless you want to make monophyly a part of the species definition.

  • And sure; biological species have no requirement of monophyly.

  • However, a recent molecular analysis (Mueller et al. 2004) rejected the monophyly of ALL of these groups with the exception of Desmognathinae (but rather than being the sister-taxon to Plethodontinae it was nested within this group, and within it the sister-taxon to a ‘Hydromantes’-Aneides clade).
