Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]
, 2012 Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Tip dating supports novel resolutions of controversial relationships among early mammals [PDF]
, 2020 The estimation of the timing of major divergences in early mammal evolution is challenging due to conflicting interpretations of key fossil taxa. One contentious group is Haramiyida, the earliest members of which are from the Late Triassic.

Phylogeographic and Ecological Insights Into the Evolutionary History of the Grass- and Sedge-Specializing Deltocephalinae Leafhoppers. [PDF]
Ecol EvolPhylogenetic reconstructions and morphological analysis robustly support the monophyletic status of tribes specializing in grass and sedge habitats. Grass‐ and sedge‐specializing groups diverged from nonspecializing groups around 95.85 million years ago (Ma) during the Cretaceous period, preceding the origin of grasses and sedges (76–88 Ma), indicating

MonoPhy: a simple R package to find and visualize monophyly issues [PDF]
PeerJ Computer Science, 2016 Background. The monophyly of taxa is an important attribute of a phylogenetic tree. A lack of it may hint at shortcomings of either the tree or the current taxonomy, or can indicate cases of incomplete lineage sorting or horizontal gene transfer ...

Recombination confounds the early evolutionary history of human immunodeficiency virus type 1: Subtype G is a circulating recombinant form [PDF]
, 2007 Human immunodeficiency virus type I (HIV-1) is classified in nine subtypes (A to D, F, G, H, J, and K), a number of subsubtypes, and several circulating recombinant forms (CRFs).

Monophyly of brachiopods and phoronids: reconciliation of molecular evidence with Linnaean classification (the subphylum Phoroniformea nov.) [PDF]
, 2000 Molecular phylogenetic analyses of aligned 18S rDNA gene sequences from articulate and inarticulate brachiopods representing all major extant lineages, an enhanced set of phoronids and several unrelated protostome taxa, confirm previous indications that ...

Why biogeographical hypotheses need a well supported phylogenetic framework: a conceptual evaluation
Papéis Avulsos de Zoologia, 2007 A growing number of biogeographical methods have attempted to describe formal means of reconstructing the biogeographical history of the organisms. Whatever the biogeographical method, however, the source of systematic information has to be well worked ...
