In an attempt to investigate differences between the most widely discussed hypotheses of
early tetrapod relationships, we assembled a new data matrix including 90 taxa coded for …

Recent discoveries of previously unknown fossil forms have dramatically transformed
understanding of many aspects of the fish-tetrapod transition. Newer paleobiological …

To investigate the predictability of genetic adaptation, we examined the molecular basis of
convergence in hemoglobin function in comparisons involving 56 avian taxa that have …

Fluorescent properties can be useful not only for tracking individual molecules within a
microenvironment, but also in molecular-scale opto-electronics. Here we use external …

Vertebrate palaeontology is a lively field, with new discoveries reported every week... and
not only dinosaurs! This new edition reflects the international scope of vertebrate …

The relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) is
well established, but the origin of major tetrapod features has remained obscure for lack of …

The fossil record of the earliest tetrapods (vertebrates with limbs rather than paired fins)
consists of body fossils and trackways. The earliest body fossils of tetrapods date to the Late …

Phylogenetic analysis of early tetrapod evolution has resulted in a consensus across diverse
data sets,, in which the tetrapod stem group is a relatively homogenous collection of medium …

The evolutionary history of osteichthyans (bony fishes plus tetrapods) extends back to the
Ludlow epoch of the Silurian period. However, these Silurian forms have been documented …

The discovery of Entelognathus revealed the presence of maxilla, premaxilla, and dentary,
supposedly diagnostic osteichthyan bones, in a Silurian placoderm. However, the …
