In this field there has been an explosion of information generated by scientific research. One of the beneficiaries of this has been the study of morphology, where new techniques and analyses have led to insights into a wide range of topics. Advances in genetics, histology, microstructure, biomechanics and morphometrics have allowed researchers to view teeth from alternative perspectives. However, there has been little communication between researchers in the different fields of dental research. This book brings together overviews on a wide range of dental topics linking genes, molecules and developmental mechanisms within an evolutionary framework. Written by the leading experts in the field, this book will stimulate co-operative research in fields as diverse as paleontology, molecular biology, developmental biology and functional morphology.
The Teeth of Mammalian Vertebrates presents a comprehensive survey of mammalian dentitions that is based on material gathered from museums and research workers from around the world.

The roots of this book and its sister volume, Mammal Phylogeny: Placentals, go back to discussions and plans, shelved for a while, between F. S. Szalay and W. P. Luckett during the international and multidisciplinary symposium on rodent evolution sponsored by NATO, July 2-6, 1984, in Paris. That conference, orga nized by W. P. Luckett and J. -L. Hartenberger, the proceedings of which were published in 1985, proved an inspiring experience to all of the participants, as this was repeatedly expressed both during and after the meetings. In addition to issues relating to rodents, general theoretical topics pertaining to the evolutionary biol ogy and systematics of other groups of mammals regularly surfaced during the presentations and discussions. M. J. Novacek, who was also a participant in the rodent symposium, shared with Luckett and Szalay the enthusiasm acquired there, and he also expressed strong interest for a meeting on mammal evolution with a general focus similar to that of the rodent gathering. In 1988, Szalay and Luckett, after having planned in detail a program, direc tion, and core list of participants, were awarded a $30,000 grant by the Alfred P. Sloan Foundation through the Research Foundation of the City University of New York. The grant was contingent upon obtaining additional funds sufficient to assure that the symposium would be held. Raising the remaining funds proved to be a problem.
Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and their evolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking at how they evolved and how recent changes to our diet are now affecting dental health. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Human children grow at a uniquely slow pace by comparison with other mammals. When and where did this schedule evolve? Have technological advances, farming and cities had any effect upon it? Addressing these and other key questions in palaeoanthropology and bioarchaeology, Simon Hillson examines the unique role of teeth in preserving detailed microscopic records of development throughout childhood and into adulthood. The text critically reviews theory, assumptions, methods and literature, providing the dental histology background to anthropological studies of both growth rate and growth disruption. Chapters also examine existing studies of growth rate in the context of human evolution and primate development more generally, together with implications for life history. The final chapters consider how defects in the tooth development sequence shed light on the consequences of biological and social transitions, contributing to our understanding of the evolution of modern human development and cognition.
Much recent research in evolutionary developmental biology has focused on the origin of new body plans. However, most evolutionary change at the population and species level consists of tinkering: small-scale alterations in developmental pathways within a single body plan. Such microevolutionary events have been well studied on a population genetic level and from the perspective of adaptive phenotypic evolution, but their developmental mechanisms remain poorly studied. This book explores both theoretical and practical issues of tinkering. It features a wide range of perspectives to address several fundamental questions. How does tinkering occur developmentally, and how is it manifested phenotypically? Are the developmental mechanisms by which tinkering occur different from those that underlie larger evolutionary changes? What are the developmental constraints on tinkering? And how do we test hypotheses about microevolutionary shifts in development from the fossil record? With contributions from experts in a range of fields, this fascinating book makes exciting reading for anyone studying evolution, developmental biology or genetics.
Although evolutionary developmental biology is a new field, its origins lie in the last century; the search for connections between embryonic development (ontogeny) and evolutionary change (phylogeny) has been a long one. Evolutionary developmental biology is however more than just a fusion of the fields of developmental and evolutionary biology. It forges a unification of genomic, developmental, organismal, population and natural selection approaches to evolutionary change. It is concerned with how developmental processes evolve; how evolution produces novel structures, functions and behaviours; and how development, evolution and ecology are integrated to bring about and stabilize evolutionary change. The previous edition of this title, published in 1992, defined the terms and laid out the field for evolutionary developmental biology. This field is now one of the most active and fast growing within biology and this is reflected in this second edition, which is more than twice the length of the original and brought completely up to date. There are new chapters on major transitions in animal evolution, expanded coverage of comparative embryonic development and the inclusion of recent advances in genetics and molecular biology. The book is divided into eight parts which: place evolutionary developmental biology in the historical context of the search for relationships between development and evolution; detail the historical background leading to evolutionary embryology; explore embryos in development and embryos in evolution; discuss the relationship between embryos, evolution, environment and ecology; discuss the dilemma for homology of the fact that development evolves; deal with the importance of understanding how embryos measure time and place both through development and evolutionarily through heterochrony and heterotrophy; and set out the principles and processes that underlie evolutionary developmental biology. With over one hundred illustrations and photographs, extensive cross-referencing between chapters and boxes for ancillary material, this latest edition will be of immense interest to graduate and advanced undergraduate students in cell, developmental and molecular biology, and in zoology, evolution, ecology and entomology; in fact anyone with an interest in this new and increasingly important and interdisciplinary field which unifies biology.
Diet is key to understanding the ecology and evolution of our distant ancestors and thier kin, the early hominins. An appreciation of the range of foods eaten by our progenitorsalso underscores just how unhealthy many of our diets are today.
This 2005 edition of The Evolution and Extinction of the Dinosaurs is a unique, comprehensive treatment of this fascinating group of organisms. It is a detailed survey of dinosaur origins, their diversity, and their eventual extinction. The book can easily be used as a teaching textbook for a class, but it is also written as a series of readable, entertaining essays covering important and timely topics appealing to non-specialists and all dinosaur enthusiasts: birds as 'living dinosaurs', the new feathered dinosaurs from China, 'warm-bloodedness'. Along the way, the reader learns about dinosaur functional morphology, physiology, and systematics using cladistic methodology - in short, how professional paleontologists and dinosaur experts go about their work, and why they find it so rewarding. The book is spectacularly illustrated by John Sibbick, a world-famous illustrator of dinosaurs, commissioned exclusively for this book.
