The origin of vertebrate limbs
The origin of vertebrate limbs is a scholarly work, published in 2021 in ''Development''. The main subjects of the publication include convergent evolution, biology, body plan, Hox gene, fin, dinosaur, Vertebrata, lineage, Actinopterygii, phylogenetics, anatomy, macroevolution, phylogenetic tree, tetrapod, evolutionary developmental biology, Notch signaling pathway, and evolutionary biology. 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.
