Background Though skeletal adaptations for locomotion in mammals are well documented, possible limb adaptations in terms of muscle architecture have received far less study. Examining mustelid mammals...

Adaptive radiations generate remarkable morphological diversity, yet traits often diversify at different rates and modes, producing mosaic patterns of evolution. Modularity, the semiautonomous organization of traits, can shape how selection and ...

Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathog...

We report the first fossil occurrence of Masturus from the Middle Miocene Hagjeon Formation of the Pohang Basin, southeastern Korea. It is referable to Masturus cf. lanceolatus based on a distincti...

First skeletal record of the pufferfish Arothron (Tetraodontiformes: Tetraodontidae) from the Early Pleistocene of southern Taiwan

Body size variation in vertebrates is a complex polygenic trait, tightly correlated with numerous aspects of a species’ biology, ecology, and physi...
