Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Karyology of the East African Caecilian Schistometopum Gregorii (Amphibia, Gymnophiona) from the Tana River Delta, Kenya [PDF]
, 2014 This report presents a male somatic karyotype (2N=22; FN=40) and late meiotic stages of Schistometopum gregorii that seems to fall in line with that of other taxa of the family Dermophiidae.

Journal of Morphology, Volume 287, Issue 5, May 2026.Total intestine length scales hyper‐allometrically, that is, at an exponent > 0.33, with body mass across vertebrates, including amphibians. ABSTRACT Across four large vertebrate groups—fish, reptiles, birds and mammals— intestine length has been shown to scale hyper‐allometrically with body mass (BM), at an exponent higher than the geometric ...

Evolutionary Applications, Volume 19, Issue 5, May 2026.ABSTRACT Type I interferons (IFNs) play essential roles in antiviral immune responses. The extensive diversification of type I IFNs into various subtypes and duplicated gene copies has posed significant challenges for evolutionary reconstruction. To address this, we developed the type I IFN sequence composition and structure (IFN‐SCOPE) model and gene ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.By analyzing 277 anuran mitochondrial genomes, this study reconstructs a robust phylogeny for frogs and toads, tracing their origins to the Triassic and major radiations to the Cretaceous‐Neogene. The research identifies 58 distinct gene arrangement patterns, providing a novel evolutionary framework.
