Many phylogenetic analyses are inspired by or depend upon the monophyly of a group specified a priori. Also, many evolutionary problems for which phytogenies are useful do not require every detail of the phylogeny to be estimated correctly but depend upon the monophyly (or lack thereof) of a particular group. We propose a likelihood-ratio test that compares whether the best trees estimated with and without the constraint of monophyly are significantly different. Simulation s...

Proliferation of phylogenetic studies based on poor taxonomic sampling or insufficient molecular evidence usually leads to conflicting results. As a consequence, advancement of systematic knowledge yields to confusion. The problem is exacerbated for taxonomic groups with historically difficult resolution of evolutionary relationships such as the flatfishes. Molecular evidence to support monophyly for this emblematic group of fishes and their interrelationships has been elusive, and a rece...

Abstract The phylum Cercozoa consists of a diverse assemblage of amoeboid and flagellated protists that forms a major component of the supergroup, Rhizaria. However, despite its size and ubiquity, the phylogeny of the Cercozoa remains unclear as morphological variability between cercozoan species and ambiguity in molecular analyses, including phylogenomic approaches, have produced ambiguous results and raised doubts about the monophyly of the group. Here we sought to resolve these ambigui...

article i nfo We present the first study to use whole mitochondrial genome sequences to examine phylogenetic affinities of the flatfishes (Pleuronectiformes). Flatfishes have attracted attention in evolutionary biology since the early his- tory of the field because understanding the evolutionary history and patterns of diversification of the group will shed light on the evolution of novel body plans. Because recent molecular studies based primarily on DNA se- quences from nuclear loci have yield...

THE existence of sympatric speciation—that populations diverge into species in the absence of physical or ecological barriers—is controversial1–6. The East African Great Lakes harbour hundreds of cichlid species representing only a few monophyletic lineages7,8, although palaeolimnological evidence9–11 and local restrictions on species distribution12 suggest that speciation in these lakes could have been allopatric13,14. The case for sympatry in restricted areas of Lakes Malawi and Tanganyika is ...

Monophyletic groups—groups that consist of all of the descendants of a most recent common ancestor—arise naturally as a consequence of descent processes that result in meaningful distinctions between organisms. Aspects of monophyly are therefore central to fields that examine and use genealogical descent. In particular, studies in conservation genetics, phylogeography, population genetics, species delimitation, and systematics can all make use of mathematical predictions under evolutionar...

The relationship between Scleractinia and Corallimorpharia, Orders within Anthozoa distinguished by the presence of an aragonite skeleton in the former, is controversial. Although classically considered distinct groups, some phylogenetic analyses have placed the Corallimorpharia within a larger Scleractinia/Corallimorpharia clade, leading to the suggestion that the Corallimorpharia are “naked corals” that arose via skeleton loss during the Cretaceous from a Scleractinian ancestor. Scleractinian ...

Abstract Phylogenetic analysis of ribosomal RNA sequences obtained from uncultivated organisms of a hot spring in Yellowstone National Park reveals several novel groups of Archaea, many of which diverged from the crenarchaeal line of descent prior to previously characterized members of that kingdom. Universal phylogenetic trees constructed with the addition of these sequences indicate monophyly of Archaea, with modest bootstrap support. The data also show a specific relationship between l...

The phylum Cnidaria is usually divided into five classes: Anthozoa, Cubozoa, Hydrozoa, Scyphozoa and Staurozoa. The class Anthozoa is subdivided into two subclasses: Hexacorallia and Octocorallia. Morphological and molecular studies based on nuclear rDNA and recent phylogenomic studies support the monophyly of Anthozoa. On the other hand, molecular studies based on mitochondrial markers, including two recent studies based on mitogenomic data, supported the paraphyly of Anthozoa, and posit...

The origin and monophyly of the polyploid cotton (Gossypium) species has been largely accepted, despite the lack of explicit phylogenetic evidence. Recent studies in other polyploid systems have demonstrated that multiple origins for polyploid species are much more common than once thought, raising the possibility that Gossypium polyploids also had multiple origins, as postulated by some authors. To test the monophyly of polyploid cotton, we sequenced a 2.8-kb intergenic region fro...
