The Anatomical Record, Volume 308, Issue 1, Page 26-44, January 2025.Abstract The vertebrate head and its skull represent a significant innovation that has played a key role in the evolutionary and ecological success of vertebrates. For a global and integral understanding of the evolution of the head skeleton, it is essential to have reliable information on the development of chondrocranium in a wide range of vertebrate

The radiation of cynodonts and the ground plan of mammalian morphological diversity [PDF]
, 2013 Cynodont therapsids diversified extensively after the Permo-Triassic mass extinction event, and gave rise to mammals in the Jurassic. We use an enlarged and revised dataset of discrete skeletal characters to build a new phylogeny for all main cynodont ...

The relationship between the secondary vascular system and the lymphatic vascular system in fish
Biological Reviews, Volume 99, Issue 6, Page 2108-2133, December 2024.ABSTRACT New technologies have resulted in a better understanding of blood and lymphatic vascular heterogeneity at the cellular and molecular levels. However, we still need to learn more about the heterogeneity of the cardiovascular and lymphatic systems among different species at the anatomical and functional levels.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals
Ecology and Evolution, Volume 14, Issue 9, September 2024.Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

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

Ecology and Evolution, Volume 14, Issue 3, March 2024.The genome of the spotted parrotfish provides insight into the evolution of a coral reef specialist. Expansion and selection of detoxifying genes suggest a potential role in the metabolism of harmful dietary targets. Abstract With over 600 valid species, the wrasses (family Labridae) are among the largest and most successful families of the marine ...
