Phylogenetic Reconstruction of Lung Evolution in Extant Squamata

open access: yesJournal of Zoology, EarlyView.
The Squamata group exhibits remarkable diversity in lung structure. However, a comprehensive understanding of how this variation evolved within the clade is still lacking. To reconstruct the evolutionary history of lungs of living squamates, we conducted comparative phylogenetic analyses using categorized lung traits, such as lung type, respiratory ...

Ethmosphenoid endocasts elucidate evolutionary brain divergences and interrelationships of stem tetrapods (Sarcopterygii, Tetrapodomorpha)

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Nearly half of all living vertebrate diversity can be traced back to a single lineage of lobe‐finned fishes (piscine sarcopterygians) that radiated during the Palaeozoic Era. In recent years, the phylogenetic framework of tetrapodomorph fishes has largely stabilized, with the exception of the ‘Osteolepiformes’, the interrelationships of which ...

Evolution and Development of the Atrial Septum

open access: yesThe Anatomical Record, Volume 302, Issue 1, Page 32-48, January 2019., 2019
ABSTRACT The complete division of the atrial cavity by a septum, resulting in a left and right atrium, is found in many amphibians and all amniotes (reptiles, birds, and mammals). Surprisingly, it is only in eutherian, or placental, mammals that full atrial septation necessitates addition from a second septum.

Darwin, Haeckel, and the “Mikluskan gas organ theory”

open access: yesDevelopmental Dynamics, Volume 253, Issue 4, Page 370-389, April 2024.
Abstract A previously unknown reference to the Russian ethnologist, biologist, and traveler Nikolai N. Miklucho‐Maclay (1846–1888) was discovered in correspondence between Charles Darwin (1809–1882) and Ernst Haeckel (1834–1919). This reference has remained unknown to science, even to Miklucho‐Maclay's biographers, probably because Darwin used the ...
