Library of Congress Cataloging in Publication Data LC Card Number ISBN 9 8 7 6 5 4 3 2 1 Printed in the United States of America on acid-free paper Preface We are pleased to present, as the opening essay in this volume, Professor Ernst Mayr’s response to our suggestion that a personal history of events and ideas that influenced his thinking, and that reflect the development of evolutionary thought for more than half a century, would be of enduring interest.
Both the scientific content of Professor Mayr’s essay and the anecdotes, interactions, and personalities that figure in it will interest every biologist and historian of evolutionary biology. There is a conceptual relationship between Mayr’s emphasis on the role of genetic coadaptation in speciation, and Sewall Wright’s conviction of the reality and importance of gene interactions. Michael Wade, using a statistical framework, contrasts Wright’s and Fisher’s views on the likely role of gene interactions, and concludes that such interactions warrant more attention by theoreticians and empiricists alike.
Moving from genetic to ecological considerations that bear on speciation, the chapter by Mark Taper and Ted Case reviews the evidence for, and theory of, character displacement.
Taper evolhtiva Case develop theory suggesting that boologia conditions for character displacement may be broader than some previous models have implied. If, as Mayr has proposed, the capacity for coexistence is an important facet of speciation, the issue of character displacement among competitors should be understood in depth. More detailed examinations of the origins of certain species are presented in the two chapters that follow.
Wen-Hsiung Li and Lori Sadler examine evidence from variation in DNA sequences on the history of Homo sapiens, addressing in particular the question of whether or not our species has experienced a substantial bottleneck in population size, and whether the characteristics of modern Homo sapiens throughout the world are attributable to replacement of Eurasian by African populations or to gene flow from Africa.

Because of their global significance, crop plants such as rice have been probably more extensively studied with respect to genetics and origins than any naturally occurring species. Studies on crop plants, when interpreted or designed in an evolutionary context, can therefore provide detailed and comprehensive information of a kind that is lacking for other species.
In rice, there emerges a rich portrait, painted by Hiroko Morishima, Yoshio Sano, and Hiko-Ichi Evvolutiva, of speciation as a process that can involve the interplay of adaptation and coadaptation with gene- level phenomena such as meiotic drive.
Pollen killers and gamete eliminators add a star-wars-like egolutiva to processes that a few years ago we might never have imagined to be anything other than gradualistic. Even though polyploidy has long been accepted as a mode of speciation in plants, its population genetic consequences have remained a rather marginal area of investigation.
Bever and Felber point out the often unexpected consequences of polyploid inheritance and emphasize that any explicit theory of speciation by polyploidy must take these genetic features into account. Speciation is the foundation of biological diversity, a macroevolutionary topic addressed blologia Warren Allmon, who organizes many familiar elements of evolutionary theory into a framework of isolate formation, persistence, and differentiation that may provide a better understanding of several major macroevolutionary and evolutivs issues.
In particular, Allmon addresses the difficult question of why, and under what conditions, improved fitness adaptation of individual organisms may increase the species diversity of a clade.
The themes of macroevolution and divergence in isolated populations are pursued by V. Louise Roth, who describes the remarkable phenomenon of dwarfism in island populations of elephants, now extinct.

By combining evidence from fossils with an analysis of the development, physiology, and ecology of extant elephants, Roth shows that even seemingly immovable morphologies can evolve rapidly under novel circumstances. Organismal fhtuyma, function, and diversity are the subjects, too, of the final essays in this volume. In an age of preoccupation with molecular mechanisms, we do well to remember that the richness of the living world lies in the behavior, physiology, and ecology of organisms – and that these are expressed by their morphological features.
Marvalee Wake’s comprehensive survey of contemporary currents in morphology shows how intimately related this field is to phylogeny, how functional morphological studies shed light on adaptation and constraints, how profound the questions are about the evolution of complexity, and how the tensions between neo-Darwinism and ‘structuralism’ might be resolved.
In a more physiological and ecological vein, A.
Douglas surveys the biology of that most neglected form of interspecific interaction, symbiosis. From the level of biochemical mechanisms to that of evolution and ecology, symbiosis has had important effects on life’s history: Douglas argues that symbiosis with microorganisms has played a key role in eukaryotes’ acquisition of diverse evolutivs critically important metabolic capacities.
