The line of descent that includes all living mammals extends back in time over 300 million years. Many of the ancient relatives of mammals that fall along this line are very different in appearance from living mammals and are frequently mistaken for reptiles such as dinosaurs. This misconception is reinforced by the fact that these animals are often referred to as “mammal-like reptiles,” a term reflecting outdated methods for classifying organisms. In reality, these ancient mammal-relatives… 

The Evolutionary Emergence of Vertebrates From Among Their Spineless Relatives

The evolutionary origin of vertebrates has been debated ad nauseam by anatomists, paleontologists, embryologists, and physiologists, but it is only now that molecular phylogenetics is providing a

FROM UNDERSTANDING EVOLUTION A Name by Any Other Tree

TLDR
The widespread availability of evolutionary trees is reshaping how biologists ask and answer biological questions, and this is the reason that elephants are left on the fence about their identity, while birds have landed in the dinosaur camp, and snakes can boast the paradoxical title of tetrapod.

Nervous systems and scenarios for the invertebrate-to-vertebrate transition

TLDR
Diversity in diversity makes it challenging to establish plausible homologies between component parts (e.g. nervous system regions) and the current understanding of the relation between genotype and phenotype is too preliminary to permit us to convert gene network data into structural features in any simple way.

A Name by Any Other Tree

Re-evaluation of the historic Canadian fossil Bathygnathus borealis from the Early Permian of Prince Edward Island

The holotype and only known specimen of Bathygnathus borealis is a partial snout with maxillary dentition of a presumed sphenacodontid from the Lower Permian (Artinskian 283–290 Ma) redbeds of Prince

Diphyodont tooth replacement of Brasilodon-A Late Triassic eucynodont that challenges the time of origin of mammals.

Two sets of teeth (diphyodonty) characterise extant mammals but not reptiles, as they generate many replacement sets (polyphyodonty). The transition in long-extinct species from many sets to only two

A review of the “venomous therocephalian” hypothesis and how multiple re-portrayals of Euchambersia have influenced its success and vice versa

TLDR
A review of the literature on Euch Chambersia shows that the venomous therocephalian hypothesis is often based on inaccurate drawings of the canine and, for post-1986 authors, it is even based on the assumption that the canine of Euchambersia is grooved, whereas it is actually only ridged.

A New Eutherocephalian (Therapsida, Therocephalia) from the Upper Permian Madumabisa Mudstone Formation (Luangwa Basin) of Zambia

TLDR
The new therocephalian therapsid Ichibengops munyamadziensis adds to a list of sister-group pairs of Wuchiapingian tetrapods in southern Gondwana and Laurasia, indicating that effective, though largely unknown, dispersal routes persisted in Pangea at least through early late Permian times.

Abstract The origin of mammals has been characterized as a gradual process, a claim based primarily on a well-preserved series of extinct nonmammalian synapsids (“mammal-like reptiles”) that span

The Ancestry of Reptiles

TLDR
The ancestry of captorhinomorph reptiles from the gephyrostegid anthracosaurs can be firmly established and the nature of the amphibian-reptilian transition must be studied on the basis of relicts of earlier groups which are contemporary with true reptiles.

Synapsid Evolution and the Radiation of Non-Eutherian Mammals

TLDR
Of all the great transitions between major structural grades within vertebrates, the transition from basal amniotes to basal mammals is represented by the most complete and continuous fossil record, extending from the Middle Pennsylvanian to the Late Triassic and spanning some 75 to 100 million years.

Evolutionary Patterns Among Permo-Triassic Therapsids*

TLDR
Synapsids form the bulk of tetrapod diversity from Early Permian to Middle Triassic times and thus can provide critical information on the nature of the Permo-Triassic extinction in the terrestrial realm.

Microanatomy of the radius and lifestyle in amniotes (Vertebrata, Tetrapoda)

TLDR
The discriminant function based on taxa of known lifestyle is used to infer the lifestyle of three extinct amniotes: the early nothosaur Pachypleurosaurus, therapsid Lystrosaurus and the synapsid Ophiacodon and these predictions are congruent with classical palaeoecological interpretations.

The oldest cynodont: new clues on the origin and early diversification of the Cynodontia

TLDR
One most parsimonious tree, from an analysis using implied weights, positions Charassognathus as the most basal cynodont, which implies that the Cynodontia initially diversified in Permian Gondwana, in what is now southern Africa.

Dates, nodes and character conflict: Addressing the Lissamphibian origin problem

TLDR
Tests of different crown topologies show that placement of amphibians within lepospondyls is not a significantly worse fit for the whole character set than a close temnospondyl‐lissamphibian relationship, and the latter phylogenetic hypothesis best captures the most coherent assembly of derived lissampshibian apomorphies.
