Cladistics, or phylogenetic systematics—an approach to discovering, unraveling, and testing hypotheses of evolutionary history—took hold during a turbulent and acrimonious time in the history of systematics. During this period—the 1960s and 1970s—much of the foundation of modern systematic methodology was established as cladistic approaches became widely accepted. Virtually complete by the end of the 1980s, the wide perception has been that little has changed. This volume vividly illustrates that cladistic methodologies have continued to be developed, improved upon, and effectively used in ever widening analytically imaginative ways.

"This multifarious volume does a splendid job of reflecting the breadth and depth of fundamental questions about the methods of systematics and biogeography, from the practical applications of conservation biology to issues of wide interest to evolutionary biologists."--Dr. Norman I. Platnick, American Museum of Natural History "A fun and informative volume that everyone interested in the subject will enjoy. This book is full of important discussions on Botany, Cladistics, and Biogeography."--Vicki Funk, National Museum of Natural History, Smithsonian Institution "The Branching Of A Paradigm is the intriguing theme of this volume on the myriad of ways cladistics has impacted modern biology. Surprises from floristics to recent thoughts on epistemology await the reader."--Dennis Stevenson, New York Botanical Garden

This new edition of a foundational text presents a contemporary review of cladistics, as applied to biological classification. It provides a comprehensive account of the past fifty years of discussion on the relationship between classification, phylogeny and evolution. It covers cladistics in the era of molecular data, detailing new advances and ideas that have emerged over the last twenty-five years. Written in an accessible style by internationally renowned authors in the field, readers are straightforwardly guided through fundamental principles and terminology. Simple worked examples and easy-to-understand diagrams also help readers navigate complex problems that have perplexed scientists for centuries. This practical guide is an essential addition for advanced undergraduates, postgraduates and researchers in taxonomy, systematics, comparative biology, evolutionary biology and molecular biology.

Species Problems and Beyond offers a collection of up-to-date essays discussing from an interdisciplinary perspective the many ramifications of the ‘Species Problem.’ The authors represent experts in the philosophy of biology, in species-level evolutionary investigations, and in biodiversity studies and conservation. Some of the topics addressed concern the context sensitivity of the term ‘species’; species as individuals, processes, natural kinds, or as ‘operative concepts’; species delimitation in the age of Big (genomic) Data; and taxonomic inflation and its consequences for conservation strategies. The carefully edited volume will be an invaluable resource for philosophers of biology and evolutionary biologists alike. – Olivier Rieppel, Rowe Family Curator of Evolutionary Biology, Negaunee Integrative Research Center, Field Museum, USA Species, or ‘the Species Problem’, is a topic in science, in the philosophy of science, and in general philosophy. In fact, it encompasses many aspects of the same problem, and these are dealt with in this volume. Species are often thought of as fundamental units of biological matter to be used in ecology, conservation, classification, and biodiversity. The chapters in this book present opposing views on the current philosophical and conceptual issues of the Species Problem in biology. Divided into four sections, Concepts and Theories, Practice and Methods, Ranks and Trees and Names, and Metaphysics and Epistemologies, the book is authored by biologists, philosophers, and historians, many leaders in their fields. Topics include ontology of species, definitions of both species category and units, species rank, speciation issues, nomenclature, ecology, and species conservation. Species Problems and Beyond aims to clarify the contemporary issues of the Species Problem. It is ideal for use in upper-level seminars and courses in Evolutionary Biology, Philosophy of Science, Philosophy of Biology, Systematics and Taxonomy, and Phylogenetics/Cladistics, and for any scholar in these fields.

This book documents Willi Hennig's founding of phylogenetic systematics and the relevancy of his work for the future of cladistics.

Recent and ongoing debates in biology and the philosophy of biology reveal a widespread dissatisfaction with traditional explanatory frameworks. There are also problems with the current definitions or circumscriptions of key concepts such as gene, species, and homology, and even of whole disciplinary fields within the life sciences, e.g. developmental biology. These contrasting views are arguably a symptom of the need to revisit traditional, unchallenged partitions between the specialist disciplines within the life sciences. In the diversity of topics addressed and approaches to move beyond the current disciplinary organization, the five essays in this volume will hopefully stimulate further exploration towards an improved articulation of life sciences.

Although many archaeologists have a good understanding of the basics in computer science, statistics, geostatistics, modeling, and data mining, more literature is needed about the advanced analysis in these areas. This book aids archaeologists in learning more advanced tools and methods while also helping mathematicians, statisticians, and computer

The Evolution of Phylogenetic Systematics aims to make sense of the rise of phylogenetic systematicsÑits methods, its objects of study, and its theoretical foundationsÑwith contributions from historians, philosophers, and biologists. This volume articulates an intellectual agenda for the study of systematics and taxonomy in a way that connects classification with larger historical themes in the biological sciences, including morphology, experimental and observational approaches, evolution, biogeography, debates over form and function, character transformation, development, and biodiversity. It aims to provide frameworks for answering the question: how did systematics become phylogenetic?

Taxonomists specializing in different groups once based phylogenetic analysis only on morphological data; molecular data was used more rarely. Although molecular systematics is routine today, the use of morphological data continues to be important, especially for phylogenetic placement of many taxa known only from fossils and rare or difficult to collect species. In addition, morphological analyses help identify potential biases in molecular analyses. And finally, scenarios with respect to morphology continue to motivate biologists: the beauty of a cheetah or a baobab does not lie in their DNA sequence, but instead on what they are and do! This book is an up-to-date revision of methods and principles of phylogenetic analysis of morphological data. It is also a general guide for using the computer program TNT in the analysis of such data. The book covers the main aspects of phylogenetic analysis and general methods to compare classifications derived from molecules and morphology. The basic aspects of molecular analysis are covered only as needed to highlight the differences with methods and assumptions for analysis of morphological datasets.

Biogeography, the study of the distribution of life on Earth, has undergone more conceptual changes, revolutions and turf wars than any other scientific field. Australasian biogeographers are responsible for several of these great upheavals, including debates on cladistics, panbiogeography and the drowning of New Zealand, some of which have significantly shaped present-day studies. Australasian biogeography has been caught in a cycle of reinvention that has lasted for over 150 years. The biogeographic research making headlines today is merely a shadow of past practices, having barely advanced scientifically. Fundamental biogeographic questions raised by naturalists a century ago remain unanswered, yet are as relevant today as they were then. Scientists still do not know whether Australia and New Zealand are natural biotic areas or if they are in fact artificial amalgamations of areas. The same question goes for all biotic areas in Australasia: are they real? Australasian biogeographers need to break this 150-year cycle, learn from their errors and build upon new ideas. Reinvention of Australasian Biogeography tells the story of the history of Australasian biogeography, enabling understanding of the cycle of reinvention and the means by which to break it, and paves the way for future biogeographical research. The book will be a valuable resource for biological and geographical scientists, especially those working in biogeography, biodiversity, ecology and conservation. It will also be of interest to historians of science.
