In the past few decades, many new discoveries have provided numerous transitional fossils that show the evolution of hoofed mammals from their primitive ancestors. We can now document the origin of the odd-toed perissodactyls, their early evolution when horses, brontotheres, rhinoceroses, and tapirs can barely be distinguished, and the subsequent evolution and radiation of these groups into distinctive lineages with many different species and interesting evolutionary transformations through… 

FROM UNDERSTANDING EVOLUTION A Name by Any Other Tree

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.

A formal analysis of phylogenetic terminology: Towards a reconsideration of the current paradigm in systematics

It is proposed that in a future revision, the BioCode should approve a dual system by recognizing both a phyletic arrangement made of clades and a phylogenetic classification made of taxa, a compromise that should make possible the coexistence of the two main opposing schools of systematics.

The mammalian forelimb diversity as a morphological gradient of increasing evolutionary versatility

The findings indicate that the macroevolutionary patterns of proximal anddistal limb segments are not the same, suggesting that strong functional selection, combined with the higher potential of development to generate variation in more distal limb structures, facilitate the evolution of high autopodial disparity in mammals.

Seven non-darwinian theories opposite to evolution

The objective of this article is to prove that “Seven non-Darwinian theories opposite to evolution”, which represents the punctuated equilibrium, the shifting balance theory, the allopatric speciation theory and the species selection theory for the macroevolution, are opposite to any kind of evolution.

The Evolution of Lateral Accessory Articulations in the Lumbar Region of Perissodactyls

The evolution of lateral accessory articulations in the lumbar region of perissodactyls is studied in order to better understand their role in the evolution of Tournaisian dentition.

In this essay I shall attempt to give an outline of the facts of record, the fossil evidence as it stands today, and the interpretation of that record, what it signifies and what it proves in the light of various aspects of modern research.

The earliest known fully quadrupedal sirenian

Eocene fossils from Jamaica are described that represent nearly the entire skeleton of a new genus and species of sirenian—the most primitive for which extensive postcranial remains are known and one of the most marked examples of morphological evolution in the vertebrate fossil record.

The First Mammals

The first mammals appear at the boundary between the Triassic and the Jurassic, most likely just before the end of the former period (see Table 3.1). Before describing them we must consider exactly

A Palaeocene proboscidean from Morocco

The discovery of a new genus in the late Palaeocene (Thanetian) epoch of Morocco (Ouled Abdoun Basin), about 7 million years older than Numidotherium, providing new evidence for a very early radiation of modern orders of placentals.

Dental evidence indicates that perissodactyls were derived from the condylarth family Phenacodontidae, and Tetraclaenodon is the most advanced form which is still unspecialized enough to have given rise to Hyracotherium.

The Evolution of North American Rhinoceroses

North America. From its first appearance about 40 million years ago, it diversified into an incredible array of taxa, with a variety of ecologies that don’t resemble any of the five living species.

Species Taxonomy, Phylogeny, and Biogeography of the Brontotheriidae (Mammalia: Perissodactyla)

A radical revision in the higher classification of brontotheres is presented and one new species, Wickia brevirhinus, is named and six other potential species are recognized but remain unnamed due to very poor fossil material.

HIGHER‐LEVEL RELATIONSHIPS OF THE RECENT EUTHERIAN ORDERS: MORPHOLOGICAL EVIDENCE

Comparison morphology and paleontology offer some compelling hypotheses that comprise a framework for studies of macromolecular traits that support groupings of the Recent orders of eutherian mammals.

Toward a Phylogenetic Classification of the Mammalia

This short paper attempts to update certain aspects of my previous review by taking into account research published since 1969, as well as work being incorporated into a new classification of the Mammalia now being prepared which wall deal with all taxonomic levels down to the subgeneric level in essentially the same style as Simpson’s (1945) classification.
