Molecular Evolution And Adaptive Radiation

This volume surveys advances in the study of adaptive radiation showing how molecular characters can be used to analyze the origin and pattern of diversification within a lineage in a non-circular fashion.

Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.

This 2004 collection of essays deals with the foundation and historical development of population biology and its relationship to population genetics and population ecology on the one hand and to the rapidly growing fields of molecular quantitative genetics, genomics and bioinformatics on the other. Such an interdisciplinary treatment of population biology has never been attempted before. The volume is set in a historical context, but it has an up-to-date coverage of material in various related fields. The areas covered are the foundation of population biology, life history evolution and demography, density and frequency dependent selection, recent advances in quantitative genetics and bioinformatics, evolutionary case history of model organisms focusing on polymorphisms and selection, mating system evolution and evolution in the hybrid zones, and applied population biology including conservation, infectious diseases and human diversity. This is the third of three volumes published in honour of Richard Lewontin.

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can cause a single ancestral species to differentiate into an impressively vast array of species inhabiting a variety of environments. Much of life's diversity has arisen during adaptive radiations. Some of the most famous recent examples include the East African cichlid fishes, the Hawaiian silverswords, and of course, Darwin's Gal--aacute--;pagos finches,. This book evaluates the causes of adaptive radiation. It focuses on the 'ecological' theory of adaptive radiation, a body of ideas that began with Darwin and was developed through the early part of the 20th Century. This theory proposes that phenotypic divergence and speciation in adaptive radiation are caused ultimately by divergent natural selection arising from differences in environment and competition between species. In The Ecology of Adaptive Radiation the author re-evaluates the ecological theory, along with its most significant extensions and challenges, in the light of all the recent evidence. This important book is the first full exploration of the causes of adaptive radiation to be published for decades, written by one of the world's best young evolutionary biologists.

The annual Evolutionary Biology Meetings in Marseille aim to bring together leading scientists, promoting an exchange of state-of-the-art knowledge and the formation of inter-group collaborations. This book presents the most representative contributions to the 13th meeting, which was held in September 2009. It comprises 21 chapters, which are organized into the following three categories: • Evolutionary Biology Concepts • Genome/Molecular Evolution • Morphological Evolution/Speciation This book offers an up-to-date overview of evolutionary biology concepts and their use in the biology of the 21st century.

Biological diversity, or biodiversity, refers to the universal attribute of all living organisms that each individual being is unique - that is, no two organisms are identical. The biology of biodiversity must include all the aspects of evolutionary and ecological sciences analyzing the origin, changes, and maintenance of the di versity of living organisms. Today biodiversity, which benefits human life in vari ous ways, is threatened by the expansion of human activities. Biological research in biodiversity contributes not only to understanding biodiversity itself but also to its conservation and utilization. The Biology of Biodiversity was the specialty area of the 1998 International Prize for Biology. The International Prize for Biology was established in 1985 in commemoration of the sixty-year reign of the Emperor Showa and his longtime devotion to biological research. The 1998 Prize was awarded to Professor Otto Thomas Solbrig, Harvard University, one of the authors of this book. In conjunction with the awarding of the International Prize for Biology, the 14th International Symposium with the theme of The Biology of Biodiversity was held in Hayama on the 9th and 10th of December 1998, with financial support by an international symposium grant from the Ministry of Education, Science, Sports and Culture of Japan. The invited speakers were chosen so as to cover four basic aspects of biodiversity: species diversity and phylogeny, ecological biodiversity, development and evolution, and genetic diversity of living organisms including human beings.

After volume 33, this book series was replaced by the journal "Evolutionary Biology." Please visit www.springer.com/11692 for further information. This volume continues bringing to readers the findings of eminent evolutionary biologists and paleobiologists. Among the topics discussed in this book are the origin of the dermal skeleton in conodont chordates, patterns of nucleotide substitution and codon usage in plasmid DNA evolution, a model to explain phenotype stability in functional systems, and inter-island speciation of Hawaiian biota.

"In a book both beautifully illustrated and deeply informative, Jonathan Losos, a leader in evolutionary ecology, celebrates and analyzes the diversity of the natural world that the fascinating anoline lizards epitomize. Readers who are drawn to nature by its beauty or its intellectual challenges—or both—will find his book rewarding."—Douglas J. Futuyma, State University of New York, Stony Brook "This book is destined to become a classic. It is scholarly, informative, stimulating, and highly readable, and will inspire a generation of students."—Peter R. Grant, author of How and Why Species Multiply: The Radiation of Darwin's Finches "Anoline lizards experienced a spectacular adaptive radiation in the dynamic landscape of the Caribbean islands. The radiation has extended over a long period of time and has featured separate radiations on the larger islands. Losos, the leading active student of these lizards, presents an integrated and synthetic overview, summarizing the enormous and multidimensional research literature. This engaging book makes a wonderful example of an adaptive radiation accessible to all, and the lavish illustrations, especially the photographs, make the anoles come alive in one's mind."—David Wake, University of California, Berkeley "This magnificent book is a celebration and synthesis of one of the most eventful adaptive radiations known. With disarming prose and personal narrative Jonathan Losos shows how an obsession, beginning at age ten, became a methodology and a research plan that, together with studies by colleagues and predecessors, culminated in many of the principles we now regard as true about the origins and maintenance of biodiversity. This work combines rigorous analysis and glorious natural history in a unique volume that stands with books by the Grants on Darwin's finches among the most informed and engaging accounts ever written on the evolution of a group of organisms in nature."—Dolph Schluter, author of The Ecology of Adaptive Radiation
