Re: Mesozoic roots of parrots and passerine birds

I imagine it is much easier to work with DNA material then making the
best guess using a skeletal comparison  analysis to form a cladogram.

cheers :)

Deep avian evolutionary relationships have been difficult to resolve
as a result of a putative explosive radiation. Our study examined ∼32
kilobases of aligned nuclear DNA sequences from 19 independent loci
for 169 species, representing all major extant groups, and recovered a
robust phylogeny from a genome-wide signal supported by multiple
analytical methods. We documented well-supported, previously
unrecognized interordinal relationships (such as a sister relationship
between passerines and parrots) and corroborated previously
contentious groupings (such as flamingos and grebes). Our conclusions
challenge current classifications and alter our understanding of trait
evolution; for example, some diurnal birds evolved from nocturnal
ancestors. Our results provide a valuable resource for phylogenetic
and comparative studies in birds.
