The evolution of fishes to tetrapods (four-limbed vertebrates) was one of the most important transformations in vertebrate evolution. Hypotheses of tetrapod origins rely heavily on the anatomy of a few tetrapod-like fish fossils from the Middle and Late Devonian period (393–359 million years ago)1. These taxa—known as elpistostegalians—include Panderichthys2, Elpistostege3,4 and Tiktaalik1,5, none of which has yet revealed the complete skeletal anatomy of the pectoral fin. Here we report a 1.57… Expand
Brain Reconstruction Across the Fish-Tetrapod Transition; Insights From Modern Amphibians
The fish-tetrapod transition (which incorporates the related fin-limb and water-land transitions) is celebrated as one of the most important junctions in vertebrate evolution. Sarcopterygian fishesExpand
Development of the Pectoral Lobed Fin in the Australian Lungfish Neoceratodus forsteri
The evolutionary transition from paired fins to limbs involved the establishment of a set of limb muscles as an evolutionary novelty. In parallel, there was a change in the topography of the spinalExpand
Sarcopterygian fin ontogeny elucidates the origin of hands with digits
TLDR
These developmental patterns indicate that the digit program originated in postaxial fin radials and later expanded anteriorly inside of a preexisting autopod-like domain during the evolution of limbs, which supports the significance of classical models proposing a bending of the tetrapod metapterygial axis. Expand
Mandibular musculature constrains brain–endocast disparity between sarcopterygians
TLDR
The results show that regions of lowest brain–endocast disparity are associated with regions of bony reinforcement directly adjacent to masticatory musculature for the mandible except in Neoceratodus and Latimeria, where there is less reinforcement away from high mandibular muscle mass. Expand
A key environmental driver of osteichthyan evolution and the fish-tetrapod transition?
TLDR
It is found that tidal ranges over 4 m were present around areas of evolutionary significance for the origin of osteichthyans and the fish-tetrapod transition, highlighting the possible importance of tidal dynamics as a driver for these evolutionary processes. Expand
A microanatomical and histological study of the scales of the Devonian sarcopterygian Miguashaia bureaui and the evolution of the squamation in coelacanths
TLDR
The scales of Miguashaia bureaui are described, revealing histological data for a Palaeozoic coelacanth in great detail and adding to the authors' knowledge on the dermal skeleton of sarcopterygians. Expand
A New Look at Carboniferous Rhizodontid Humeri (Sarcopterygii; Tetrapodomorpha)
ABSTRACT The Rhizodontida are a group of tetrapodomorph sarcopterygian fishes with a worldwide distribution in the Devonian and Carboniferous periods. Rhizodontids were first described in the U.K.,Expand
The Shh/Gli3 gene regulatory network precedes the origin of paired fins and reveals the deep homology between distal fins and digits
TLDR
It is shown that Gli3 functions in controlling the proliferative expansion of distal progenitors are shared among median and paired fins as well as tetrapod limbs and that the distal regions of median fins, paired fins, and limbs retain a deep regulatory and functional homology that predates the origin of paired appendages. Expand
Anatomic position determines oncogenic specificity in melanoma
TLDR
The data suggest that the anatomic position of the cell of origin endows it with a unique transcriptional state that makes it susceptible to only certain oncogenic insults, including BRAF mutations in cutaneous melanoma but CRKL amplifications in acral melanoma. Expand
Evolution: The deep genetic roots of tetrapod-specific traits
Based on embryology and comparative genomics, recent studies reveal that genetic pathways and gene regulatory elements responsible for the invasion of land by tetrapod ancestors are deeply conservedExpand

The pectoral fin of Panderichthys and the origin of digits
TLDR
A CT scan study of an undisturbed pectoral fin of Panderichthys is presented demonstrating that the plate-like ‘ulnare’ of previous reconstructions is an artefact and that distal radials are in fact present and makes a strong case for fingers not being a novelty of tetrapods but derived from pre-existing distal Radials present in all sarcopterygian fish.

Ancestry of the Tetrapods
DURING the last few decades it has become increasingly clear that theTetrapods were derived from a group of fishes having their closest affinities with the Devonian Crossopterygii and Dipnoi. InExpand

TLDR
A composite framework of several phylogenetic hypotheses is presented incorporating living and fossil taxa, including the first report of an acanthodian metapterygium and a new reconstruction of the axial skeleton and caudal fin of Acanthostega gunnari, indicating further directions for comparative experimental research.

A Devonian tetrapod-like fish and the evolution of the tetrapod body plan
TLDR
The discovery of a well-preserved species of fossil sarcopterygian fish from the Late Devonian of Arctic Canada that represents an intermediate between fish with fins and tetrapods with limbs, and provides unique insights into how and in what order important tetrapod characters arose is reported. Expand
A Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution
TLDR
A large, lobe-finned fish from the Late Devonian of China disrupts previously accepted stem-tetrapod phylogeny and reveals parallel evolution within the lineage, suggesting that ecological diversity and biogeographical provinciality in the tetrapod stem group have been underestimated. Expand
Tetrapod-like middle ear architecture in a Devonian fish
TLDR
It is shown that the spiracular region is radically transformed from osteolepiforms and represents the earliest stages in the origin of the tetrapod middle ear architecture, suggesting that the middle ear of early tetrapods evolved initially as part of a spiracular breathing apparatus. Expand
Pectoral girdle and fin anatomy of Gogonasus andrewsae long, 1985: Implications for tetrapodomorph limb evolution
TLDR
A phylogenetic analysis indicates a more stemward position for Gogonasus in a weakly supported clade with other “osteolepidid” taxa, compared to other recent studies placing Gog onasus crownward of osteolespidid fishes and the Tristichopteridae, as the sister taxon to the “Elpistosteglia” + Tetrapoda.

The postcranial skeleton of the Devonian tetrapod Tulerpeton curtum Lebedev
TLDR
A cladistic analysis indicates that Tulerpeton is a reptiliomorph stem-group amniote and the earliest known crown-group tetrapod: Acanthostega and Ichthyostega are successively more derived plesion stem- group tetrapods and do not consititute a monophyletic ichthyostegalian radiation. Expand
The pelvic fin and girdle of Panderichthys and the origin of tetrapod locomotion
TLDR
The evolution of tetrapod locomotion appears to have passed through a stage of body-flexion propulsion, in which the pelvic fins played a relatively minor anchoring part, before the emergence of hindlimb-powered propulsion in the interval between Panderichthys and Acanthostega. Expand

Elginerpeton, described here on the basis of cranial remains from Scat Craig, is, together with the fragmentary genus Obruchevichthys from the Upper Frasnian of Latvia and Russia, the oldest known stem tetrapod. Expand
