Monophyly or Diphyly in the Origin of Whales [PDF]
Evolution, 1968 The phyletic unity of the Cetacea is still a matter of dispute. Recently Yablokov (1964; see also Kleinenberg, 1958, 1959) has given well-reasoned arguments that much of the aquatic adaptation of the two recent suborders was evolved separately, from an ancestor without these adaptations.

EEF2 analysis challenges the monophyly of Archaeplastida and Chromalveolata. [PDF]
PLoS ONE, 2008 BackgroundClassification of eukaryotes provides a fundamental phylogenetic framework for ecological, medical, and industrial research. In recent years eukaryotes have been classified into six major supergroups: Amoebozoa, Archaeplastida, Chromalveolata ...

Cryptic lineages and standing genetic variation across independent cane toad introductions
Molecular Ecology, Volume 31, Issue 24, Page 6440-6456, December 2022., 2022 Abstract Widespread introduced species can be leveraged to investigate the genetic, ecological and adaptive processes underlying rapid evolution and range expansion, particularly the contributions of genetic diversity to adaptation. Rhinella marina, the cane toad, has been a focus of invasion biology for decades in Australia.

Phylogeny of some species of Astragalus (Fabaceae) based on morphological data
یافتههای نوین در علوم زیستی, 2020 The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program.

Coming to America: Multiple Origins of New World Geckos [PDF]
, 2011 Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]
, 2013 Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have extremely streamlined, A+T-biased genomes.

Systematic Entomology, Volume 48, Issue 1, Page 69-96, January 2023., 2023 A reevaluation of †Tshecardocoleidae revealed that crucial character transformations took place in the Permian. Phylogenetic analyses show that Coleoptera excluding †Tshecardocoleidae are strongly supported as a clade (Mesocoleoptera). Taxon exclusion experiments demonstrate that †Tshecardocoleidae are crucial for understanding the early evolution of ...

Wing base structural data support the sister relationship of megaloptera and neuroptera (insecta: neuropterida). [PDF]
PLoS ONE, 2014 The phylogenetic status and the monophyly of the holometabolous insect order Megaloptera has been an often disputed and long unresolved problem. The present study attempts to infer phylogenetic relationships among three orders, Megaloptera, Neuroptera ...

Inferring Kangaroo Phylogeny from Incongruent Nuclear and Mitochondrial Genes [PDF]
, 2015 The marsupial genus Macropus includes three subgenera, the familiar large grazing kangaroos and wallaroos of M. (Macropus) and M. (Osphranter), as well as the smaller mixed grazing/browsing wallabies of M. (Notamacropus).
