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.

This book is not intended to give a full and comprehensive account of the Mesozoic mammals, and nor is it intended as a handbook for research workers studying pre-Tertiary mammals. Our intention is to give an account of the origin and evolution of certain of the characters of the Mammalia. We have tried to portray the fossils we describe as the living animals they once were, not as dead bones. Our account ends with the end of the Lower Cretaceous, since by that time the major characters of the mammals had become established. There exist a number of characters which, at the present day, are confined to the Mammalia. These include: (1) a jaw articulation formed by the squamosal and the dentary; (2) a chain of three bones, malleus, incus and stapes connecting the tympanic membrane to the inner ear; (3) the presence of hair or fur; (4) the presence of milk-glands in the female; (5) the left aortic arch is the systemic arch; (6) the phalangeal formula in both manus and pes is 2.3.3.3.3; (7) some of the teeth have more than one root. Of these characters (1) or (2) are sufficient by themselves to define a mammal; characters (6) and (7) are known to have been already in existence in some of the mammal-like reptiles - the ancestors of the mammals.

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.

Evolution on islands differs in a number of important ways from evolution on mainland areas. Over millions of years of isolation, exceptional and sometimes bizarre mammals evolved on islands, such as pig-sized elephants and hippos, giant rats and gorilla-sized lemurs that would have been formidable to their mainland ancestors. This timely and innovative book is the first to offer a much-needed synthesis of recent advances in the exciting field of the evolution and extinction of fossil insular placental mammals. It provides a comprehensive overview of current knowledge on fossil island mammals worldwide, ranging from the Oligocene to the onset of the Holocene. The book addresses evolutionary processes and key aspects of insular mammal biology, exemplified by a variety of fossil species. The authors discuss the human factor in past extinction events and loss of insular biodiversity. This accessible and richly illustrated textbook is written for graduate level students and professional researchers in evolutionary biology, palaeontology, biogeography, zoology, and ecology.

This book summarizes the most relevant published paleontological information, supplemented by our own original work, on the record of Mesozoic mammals’ evolution, their close ancestors and their immediate descendants. Mammals evolved in a systematically diverse world, amidst a dynamic geography that is at the root of the 6,500 species living today. Fossils of Mesozoic mammals, while rare and often incomplete, are key to understanding how mammals have evolved over more than 200 million years. Mesozoic mammals and their close relatives occur in a few dozen localities from Argentina, Brazil, Chile, Bolivia, and Peru spanning from the Mid- Triassic to the Late Cretaceous, with some lineages surviving the cataclysmic end of the Cretaceous period, into the Cenozoic of Argentina. There are roughly 25 recognized mammalian species distributed in several distinctive lineages, including australosphenidans, multituberculates, gondwanatherians, eutriconodonts, amphilestids and dryolestoids, among others. With its focus on diversity, systematics, phylogeny, and their impact on the evolution of mammals, there is no similar book currently available.

Relative newcomers within the story of evolution, mammals are hugely successful and have colonized land, water, and air. Tom Kemp discusses the great diversity of mammalian species, and looks at how their very disparate characteristics, physiologies, and behaviours are all largely driven by one uniting factor: endothermy, or warm-bloodedness.

Winner, 2010 PROSE Award for Excellence in the Biological Sciences. Professional and Scholarly Publishing division of the Association of American Publishers In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists.
