Non-mammalian synapsids were the dominant terrestrial vertebrates from the Late Carboniferous to the Middle Triassic and play a key role in understanding the origin and evolution of mammals. Despite these facts and the outstanding fossil record of the group, early synapsids remain obscure. This book showcases the full breadth of contemporary research on non-mammalian synapsids, ranging from taxonomy and phylogenetics to functional morphology, biogeography, paleoecology, and patterns of diversity. It also underscores the importance and potential of studying non-mammalian synapsid paleobiology in its own right, not just in the context of mammalian evolution.

The Synapsida are the 'mammal-like' reptiles and mammals, a group that diverged from a common ancestor shared with reptiles and birds about 340 million years. The fossil record of the synapsids is extraordinarily good, and documents the three phases of the history of the group, each one of which points to important evolutionary generalisations as well as relating an intrinsically fascinating story. The first stage leads from the origin of the group to the earliest mammals. The non-mammalian synapsids constituted the first radiation of fully terrestrial vertebrates, dominating the land long before the dinosaurs displaced them and took over that role. The fossil record illustrates the relationship between this radiation and the environmental conditions of the Permo-Triassic when it occurred. It also illustrates to a far greater degree than any other fossil record the origin of a major new taxon. The sequence of acquisition of mammalian structures and functions inferred from the fossils leads to an interpretation about the processes involved in the evolution of mammalian biological organisation. The second stage is the Mesozoic history of mammals. Throughout the Jurassic and Cretaceous Periods, mammals remained small, insectivorous or omnivorous animals living a nocturnal existence. They were abundant and diverse, but failed completely to evolve into any of the middle-sized and large-sized forms familiar amongst today's mammals. This is usually, though not completely satisfactorily, explained by competitive exclusion by dinosaurs. The third stage is the great Cenozoic radiation of mammals. From the moment the dinosaurs disappeared 65 million years ago, new kinds of mammals proceeded to evolve. Medium and large bodied herbivore and carnivore groups appeared early, and from then onwards a kaleidoscope of origins, flourishings, and extinctions of lineages of mammals took place. This great story interweaves changing climates, shifting continents, ecological opportunities, and the fulfilment of the adaptive potential of Mammalia. The latest molecular evidence that is having a huge impact on ideas about the timing and origins of the modern mammalian taxa is discussed along with the fossil evidence. The book reviews these three stages in turn, bringing up to date the palaeontological evidence and incorporating the molecular taxonomic data that has been rapidly accumulating over the last few years, and which is responsible for a series of exciting, radicalnew ideas about relationships amongst mammals and their inferred palaeo-biogeographic history.

There are nearly 6,000 mammalian species, among them our own. Research on our evolutionary cousins has a long history, but the last 20 years have seen particularly rapid progress in disentangling the interrelationships and evolutionary history of mammals. The present volume combines up-to-date reviews on mammalian phylogenetics with paleontological, taxonomic and evolutionary chapters and also summarizes the historical development of our insights in mammalian relationships, and thus our own place in the Tree of Life. Our book places the present biodiversity crisis in context, with one in four mammal species threatened by extinction, and reviews the distribution and conservation of mammalian diversity across the globe. This volume is the introductory tome to the new Mammalia series of the Handbook of Zoology and will be essential reading for mammalogists, zoologists and conservationists alike.

For most of us, the story of mammal evolution starts after the asteroid impact that killed the dinosaurs, but over the last 20 years scientists have uncovered new fossils and used new technologies that have upended this story. In Beasts Before Us, palaeontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over three-hundred million years ago. They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them. Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers. This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

Mammals are the dominant large animals of today, occurring in virtually every environment. This book is an account of the remarkable 320 million year long fossil record that documents their origin, their long spell as no more than small, nocturnal creatures, and their explosive radiation since the extinction of the dinosaurs 65 million years ago. Tom Kemp also unveils the exciting molecular evidence, which, coupled with important new fossils, is presently challenging current thinking on the interrelationships and historical biogeography of mammals. The Origin and Evolution of Mammals will be of interest to advanced undergraduate and graduate students as well as researchers in vertebrate palaeontology, biogeography, mammalian systematics and molecular taxonomy. It will also be welcomed by vertebrate fossil enthusiasts and evolutionary biologists of all levels with an interest in macroevolutionary problems.

The natural world is infinitely complex and hierarchically structured, with smaller units forming the components of larger systems: genes are components genomes, cells are building blocks of tissues and organs, individuals are members of populations, which, in turn, are parts of species. In the face of such awe inspiring complexity, scientists need tools like the hierarchy theory of evolution, which provides a theoretical framework and an interdisciplinary research program that aims to understand the way complex biological systems work and evolve. The multidisciplinary approach looks at the structure of the myriad intricate interactions across levels of organization that range from molecules to the biosphere. Evolutionary Theory: A Hierarchical Perspective provides an introduction to the theory, which is currently driving a great deal of research in bioinformatics and evolutionary theory. Written by a diverse and renowned group of contributors, and edited by the founder of Hierachy Theory Niles Eldredge, this work will help make transparent the fundamental patterns driving living sytems.

Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and recommendations governing phylogenetic nomenclature. Nearly 300 clades - lineages of organisms - are defined by reference to hypotheses of phylogenetic history rather than by taxonomic ranks and types. This volume will document the Real World uses of PhyloCode and will govern and apply to the names of clades, while species names will still be governed by traditional codes. Key Features Provides clear regulations for implementing new guidelines for naming lineages of organisms incorporates expressly evolutionary and phylogenetic principles Works with existing codes of nomenclature Eliminates the reliance on rank-based classification in favor of phylogenetic relationships Related Titles: Rieppel, O.
