Ancient Phylogenetic Relationships

Theoretical Population Biology, 2002
Traditional views on deep evolutionary events have been seriously challenged over the last few years, following the identification of major pitfalls affecting molecular phylogeny reconstruction. Here we describe the principally encountered artifacts, notably long branch attraction, and their causes (i.e., difference in evolutionary rates, mutational ...

Phylogenetic relationships of theJuglandaceae

Plant Systematics and Evolution, 1994
A cladistic analysis of molecular data from the chloroplast generbcL was used to examine the taxonomic relationships of the walnut family (Juglandaceae). In addition, chemical and morphological data from a previous study byHufford (1992) were incorporated, expanded, and analyzed independently and in combination with the molecular data.

Phylogenetic analysis of anthropoid relationships

Journal of Human Evolution, 1998
The relationships of anthropoids to other primates are currently debated, as are the relationships among early fossil anthropoids and crown anthropoids. To resolve these issues, data on 291 morphological characters were collected for 57 taxa of living and fossil primates and analyzed using PAUP and MacClade.

Taxonomy and phylogenetic relationship of zokors

Journal of Genetics, 2020
Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus.

Phylogenetic relationships of cyphelloid homobasidiomycetes

Molecular Phylogenetics and Evolution, 2004
The homobasidiomycetes includes the mushroom-forming fungi. Members of the homobasidiomycetes produce the largest, most complex fruiting bodies in the fungi, such as gilled mushrooms ("agarics"), boletes, polypores, and puffballs. The homobasidiomycetes also includes species that produce minute, cup- or tube-shaped "cyphelloid" fruiting bodies, that ...

Phylogenetic Relationships

1997
Publisher Summary This chapter provides an overview of the phylogenetic structure of the genus clostridium. The formation of endospores is a monophyletic trait that is expressed in a few genera of the Clostridium/Bacillus subphylum of Gram-positive bacteria. Loss of spore formation and changes in morphology led to the evolution of phenotypes that were

THE PHYLOGENETIC RELATIONSHIP OF OPHIOGLOSSACEAE

TAXON, 1988
SummaryThe systematic position of Ophioglossaceae was examined using available evidence from recent anatomical and morphological studies. Although the Ophioglossaceae are free‐sporing vascular plants like the Filicopsida, and are therefore commonly placed in that group, the character correlation of eustelic or sympodial primary vascular system of stem,

Phylogenetic Relationships of the Platyrrhini [PDF]

open access: possible, 1980
The major problem addressed in this volume concerns the origin of the New World monkeys. This problem is sometimes simplified to the question of whether they came from North America or from Africa. However, the biological problem is actually more complex and can be treated as four separate hypotheses: (1) descent of platyrrhines from an omomyid ...

Phylogenetic relationships of the Santalales and relatives

Journal of Molecular Evolution, 1990
Determining relationships among parasitic angiosperms has often been difficult owing to frequent morphological reductions in floral and vegetative features. We report 18S (small-subunit) rRNA sequences for representative genera of three families within the Santalales (Olacaceae, Santalaceae, and Viscaceae) and six outgroup dicot families (Celastraceae,
