The origin and early phylogenetic history of jawed vertebrates
MD Brazeau, M Friedman - Nature, 2015 - nature.com
Fossils of early gnathostomes (or jawed vertebrates) have been the focus of study for nearly
two centuries. They yield key clues about the evolutionary assembly of the group's common …

Facts and fancies about early fossil chordates and vertebrates
P Janvier - Nature, 2015 - nature.com
The interrelationships between major living vertebrate, and even chordate, groups are now
reasonably well resolved thanks to a large amount of generally congruent data derived from …

The oldest complete jawed vertebrates from the early Silurian of China
Molecular studies suggest that the origin of jawed vertebrates was no later than the Late
Ordovician period (around 450 million years ago (Ma)),. Together with disarticulated micro …

Predictable convergence in hemoglobin function has unpredictable molecular underpinnings
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 …

[HTML][HTML] Constraints on the timescale of animal evolutionary history
Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …

[HTML][HTML] Tracing the genetic footprints of vertebrate landing in non-teleost ray-finned fishes
Rich fossil evidence suggests that many traits and functions related to terrestrial evolution
were present long before the ancestor of lobe-and ray-finned fishes. Here, we present …

Hagfish from the Cretaceous Tethys Sea and a reconciliation of the morphological–molecular conflict in early vertebrate phylogeny
T Miyashita, MI Coates, R Farrar… - Proceedings of the …, 2019 - National Acad Sciences
Hagfish depart so much from other fishes anatomically that they were sometimes considered
not fully vertebrate. They may represent:(i) an anatomically primitive outgroup of vertebrates …

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

Bayesian morphological clock methods resurrect placoderm monophyly and reveal rapid early evolution in jawed vertebrates
The phylogeny of early gnathostomes provides an important framework for understanding
one of the most significant evolutionary events, the origin and diversification of jawed …

Copulation in antiarch placoderms and the origin of gnathostome internal fertilization
Reproduction in jawed vertebrates (gnathostomes) involves either external or internal
fertilization. It is commonly argued that internal fertilization can evolve from external, but not …
