Fins of fishes provide many examples of structures that are beautifully designed to power
and control movement in water; however, some species also use their fins for substrate …

Chordates comprise lampreys, hagfishes, jawed fishes, and tetrapods, plus a variety of more
unfamiliar and crucially important non-vertebrate animal lineages, such as lancelets and sea …

Amphibious fishes show wide variation in form and function. Examination of terrestrial
locomotion in fishes has largely focused on highly specialized taxa. From an evolutionary …

To investigate the morphology and evolutionary origin of muscles in vertebrate limbs, we
conducted anatomical dissections, computed tomography and kinematic analyses on the …

The fin-to-limb transition is heralded as one of the most important events in vertebrate
evolution. Over the last few decades our understanding of how limbs evolved has …

Previous accounts of the origin of tetrapod limbs have postulated a relatively sudden
change, after the split between extant lobe-finned fish and tetrapods, from a very simple fin …

Muscle fiber types in the pectoral fins of fishes have rarely been examined, despite their
morphological and functional diversity. Here, we describe the distribution of fast and slow …

The ability of bones to sense and respond to mechanical loading is a central feature of
vertebrate skeletons. However, the functional demands imposed on terrestrial and aquatic …

In the last decades, Danio rerio became one of the most used model organisms in various
evo‐devo studies devoted to the fin skeletal anatomy and fin‐limb transition. Surprisingly …
