The distribution and classification of life on earth has long been of interest to biological theorists, as well as to travellers and explorers. Cladistic biogeography is the study of the historical and evolutionary relationships between species, based on their particular distribution patterns across the earth. Analysis of the distributions of species in different areas of the world can tell us how those species and areas are related, what regions or larger groups of areas exist, and what their origins might be. The first edition of Cladistic Biogeography was published in 1986. It was a concise exposition of the history, methods, applications of, and prospects for cladistic biogeography. Well reviewed, and widely used in teaching, Cladistic Biogeography is still in demand, despite having been out of print for some time. This new edition draws on a wide range of examples, both plant and animal, from marine, terrestrial, and freshwater habitats. It has been updated throughout, with the chapters being rewritten and expanded to incorporate the latest research findings and theoretical and methodological advances in this dynamic field.
