Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

FEBS Open Bio, Volume 16, Issue 8, Page 1477-1490, August 2026.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

The Backbone of Regionalisation: Refining Axial Regionalisation Through 3D Morphometric Sampling Strategies on Elapid Snakes

Journal of Morphology, Volume 287, Issue 8, August 2026.
Using 3D geometric morphometrics on every precaudal vertebra from 12 elapid snakes, this study used segmented linear regression to test regionalisation. The results show a five‐region model is best supported, including short cervical and lumbar regions and a strong heart‐aligned boundary at approximately 20% of the pre‐caudal column.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

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 ...

Amphibian Intestine Allometry

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 ...

Locus‐Specific Convergent Evolution and Interchromosomal Rearrangements Contribute to the Diversification of Amniote Type I Interferons

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 ...
