An analysis of convergent evolution from molecules to ecosystems, demonstrating the limited number of evolutionary pathways available to life. Charles Darwin famously concluded On the Origin of Species with a vision of "endless forms most beautiful" continually evolving. More than 150 years later many evolutionary biologists see not endless forms but the same, or very similar, forms evolving repeatedly in many independent species lineages. A porpoise's fishlike fins, for example, are not inherited from fish ancestors but are independently derived convergent traits. In this book, George McGhee describes the ubiquity of the phenomenon of convergent evolution and connects it directly to the concept of evolutionary constraint--the idea that the number of evolutionary pathways available to life are not endless, but quite limited. Convergent evolution occurs on all levels, from tiny organic molecules to entire ecosystems of species. McGhee demonstrates its ubiquity in animals, both herbivore and carnivore; in plants; in ecosystems; in molecules, including DNA, proteins, and enzymes; and even in minds, describing problem-solving behavior and group behavior as the products of convergence. For each species example, he provides an abbreviated list of the major nodes in its phylogenetic classification, allowing the reader to see the evolutionary relationship of a group of species that have independently evolved a similar trait by convergent evolution. McGhee analyzes the role of functional and developmental constraints in producing convergent evolution, and considers the scientific and philosophical implications of convergent evolution for the predictability of the evolutionary process.

Scholars from a variety of disciplines consider cases of convergence in lithic technology, when functional or developmental constraints result in similar forms in independent lineages. Hominins began using stone tools at least 2.6 million years ago, perhaps even 3.4 million years ago. Given the nearly ubiquitous use of stone tools by humans and their ancestors, the study of lithic technology offers an important line of inquiry into questions of evolution and behavior. This book examines convergence in stone tool-making, cases in which functional or developmental constraints result in similar forms in independent lineages. Identifying examples of convergence, and distinguishing convergence from divergence, refutes hypotheses that suggest physical or cultural connection between far-flung prehistoric toolmakers. Employing phylogenetic analysis and stone-tool replication, the contributors show that similarity of tools can be caused by such common constraints as the fracture properties of stone or adaptive challenges rather than such unlikely phenomena as migration of toolmakers over an Arctic ice shelf.

Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.

Twelve renowned scientists and theologians offer penetrating insights into the evolution dialogue in The Deep Structure of Biology. Each considers whether the orthodox model of evolution is sufficient and offers his/her own perspective on evolution and biology. Essays include: •Chance and Necessity in Evolution •Green Plants as Intelligent Organisms •Canny Corvoids and Political Primates: A Case for Convergent Evolution in Intelligence •Social and Cultural Evolution in the Ocean: Convergences and Contrasts with Terrestrial Systems •Purpose in Nature: On the Possibility of a Theology of Evolution Editor Simon Conway Morris provides the introduction and an overview of the issues as well as an essay on evolution and convergence. Other contributors are: Richard Lenski, George McGhee, Karl Niklas, Anthony Trewavas, Nigel Franks, Nicola Clayton, Nathan Emery, HalWhitehead, Robert Foley, Michael Ruse, Celia Deane-Drummond, and John Haught. The discussion of biology and evolution in these essays broadens the scope of the traditional evolution discussion as it aims to stimulate the development of further research programs. Scholars in the science and religion field will find this book a valuable resource.

During the last ten years, remarkable progress has occurred in the study of molecular evolution. Among the most important factors that are responsible for this progress are the development of new statistical methods and advances in computational technology. In particular, phylogenetic analysis of DNA or protein sequences has become a powerful tool for studying molecular evolution. Along with this developing technology, the application of the new statistical and computational methods has become more complicated and there is no comprehensive volume that treats these methods in depth. Molecular Evolution and Phylogenetics fills this gap and present various statistical methods that are easily accessible to general biologists as well as biochemists, bioinformatists and graduate students. The text covers measurement of sequence divergence, construction of phylogenetic trees, statistical tests for detection of positive Darwinian selection, inference of ancestral amino acid sequences, construction of linearized trees, and analysis of allele frequency data. Emphasis is given to practical methods of data analysis, and methods can be learned by working through numerical examples using the computer program MEGA2 that is provided.

Recent advances in understanding the thermodynamics of macromolecules, the topological properties of gene networks, the organization and mutation capabilities of genomes, and the structure of populations make it possible to incorporate these key elements into a broader and deeply interdisciplinary view of molecular evolution. This book gives an account of such a new approach, through clear tutorial contributions by leading scientists.

This novel book is the first to properly address the controversial issue of plant intelligence, arguing convincingly that cells and whole plants growing in competitive wild conditions exhibit aspects of plant behaviour that can be accurately described as intelligent". The author expands on three main insights drawn by the Nobel Prize winning botanist Barbara McClintock: firstly that plant cells may have knowledge of themselves; secondly that they receive challenges which lead to behavioural changes; finally, that they do so in a manner which implies assessment and intelligent behaviour. By equating the concept of intelligent behaviour with that of adaptively variable behaviour, the book provides a novel integration of signalling, behaviour, and behavioural ecology, all set within the context of plant studies. Plant Behaviour and Intelligence begins with chapters on the origins and multicellular nature of plant life, before going on to discuss novel behaviours such as branch initiation and growth, unusual behaviour of leaves, and how roots reconstruct their sensing systems and are capable of self-recognition. An entire chapter is devoted to the nature of intelligence and another to the vexed question of "consciousness", as applied to plant life. This advanced textbook will be suitable for senior undergraduate and graduate level students taking related courses in plant ecology and evolution. It will also be of relevance and use to a broader audience of professional plant ecologists seeking an authoritative reference text to help them navigate the complexity and controversy of plant behaviour."
