Royal Society Open Science, 2022 The Ovalentaria is a taxon of teleosts that has been proposed based on molecular analyses only. Previously widely separated families are assembled in this taxon. For the first time, the Ovalentaria are analysed using a comparative morphological approach.

Nonadaptive Amino Acid Convergence Rates Decrease over Time. [PDF]
, 2015 Convergence is a central concept in evolutionary studies because it provides strong evidence for adaptation. It also provides information about the nature of the fitness landscape and the repeatability of evolution, and can mislead phylogenetic inference.

Evolutionary bedfellows: Reconstructing the ancestral state of autotomy and regeneration
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2020 Abstract Some form of regeneration occurs in all lifeforms and extends from single‐cell organisms to humans. The degree to which regenerative ability is distributed across different taxa, however, is harder to ascertain given the potential for phylogenetic constraint or inertia, and adaptive processes to shape this pattern.

Evolutionary modes in protein observable space: the case of Thioredoxins [PDF]
, 2019 In this article, we investigated the structural and dynamical evolutionary behaviour of a set of ten thioredoxin proteins as formed by three extant forms and seven resurrected ones in laboratory.

The evolutionary history of Stomatopoda (Crustacea: Malacostraca) inferred from molecular data [PDF]
PeerJ, 2017 The crustacean order Stomatopoda comprises seven superfamilies of mantis shrimps, found in coastal waters of the tropics and subtropics. These marine carnivores bear notable raptorial appendages for smashing or spearing prey.

A flat petal as ancestral state for Ranunculaceae
Frontiers in Plant Science, 2022 Ranunculaceae comprise ca. 2,500 species (ca. 55 genera) that display a broad range of floral diversity, particularly at the level of the perianth. Petals, when present, are often referred to as “elaborate” because they have a complex morphology.

Islands contribute disproportionately high amounts of evolutionary diversity in passerine birds [PDF]
, 2015 Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major ...

Analysis on the reconstruction accuracy of the Fitch method for inferring ancestral states
BMC Bioinformatics, 2011 Background As one of the most widely used parsimony methods for ancestral reconstruction, the Fitch method minimizes the total number of hypothetical substitutions along all branches of a tree to explain the evolution of a character. Due to the extensive

Genomics reveals historic and contemporary transmission dynamics of a bacterial disease among wildlife and livestock [PDF]
, 2016 Whole-genome sequencing has provided fundamental insights into infectious disease epidemiology, but has rarely been used for examining transmission dynamics of a bacterial pathogen in wildlife.
