Darwin’s Fishes An Encyclopedia of Ichthyology, Ecology, and Evolution In Darwin’s Fishes, Daniel Pauly presents a unique encyclopedia of ichthyology, ecology, and evolution, based upon everything that Charles Darwin ever wrote about fish. Entries are arranged alphabetically and can be about, for example, a particular fish taxon, an anatomical part, a chemical substance, a scientist, a place, or an evolutionary or ecological concept. Readers can start wherever they like and are then led by a series of cross-references on a fascinating voyage of interconnected entries, each indirectly or directly connected with original writings from Darwin himself. Along the way, the reader is offered interpretation of the historical material put in the context of both Darwin’s time and that of contemporary biology and ecology. This book is intended for anyone interested in fishes, the work of Charles Darwin, evolutionary biology and ecology, and natural history in general. DANIEL PAULY is the Director of the Fisheries Centre, University of British Columbia, Vancouver, Canada. He has authored over 500 articles, books and papers.

Darwin is known for writing about many things, with superb works on orchids and barnacles and, of course, on natural selection. Many authors have written about him and we often hear refer- ence to ‘Darwin’s finches’. I suspect few people connect Darwin with fishes: this now will change. Daniel Pauly has done a superb job in this book in showing us the many connections between Darwin and fishes. He does this in a delightful way, mixing subtle, cryptic humour with academic discussions. Pauly gives us a tour in discovering fascinating facts; it’s a great way to learn about fishes. Daniel Pauly is internationally known for his work on fish growth and mortal- ity, tropical fisheries management, and ecosystem modelling. A recognized leader in studies of fish population dynamics, he is also well known for his insights into the historic and socio-economic factors that intervene when fish popula- tions are exploited. These, combined with his wide interests in evolutionary sub- jects, allowed a masterful treatment of Darwin’s contributions to ichthyology, the subject of this book. The book is arranged like an encyclopedia, with items in alphabetical order. The generous cross-references allow the reader to start with a given term of interest and go on an exciting voyage of discovery, exploring all sorts of worlds. One can start from a given fish taxon (by common or scientific name) and be led through, for example, an anatomical part, to a biologist or other scientist, a scientific phe- nomenon, an ecological or evolutionary subject, a philosopher, a chemical element, a geographic location, some form of life other than a fish, a museum, and then back to some fish. All the topics, however, lead directly or indirectly to the work of Darwin, perhaps the most influential person in biology. The reader never knows where the journey will lead, perhaps to an old fossil, to Louis Agassiz, or to a species flock undergoing evolution. An exciting mixture of topics enters in as we take off in whatever direction we wish. Readers get into whole organismal biology (and respect for whole organismal biology is under serious threat in many so-called ‘Biology’ Departments), and it is fun to challenge ourselves in seeing just what we know or do not know on given subjects. Resources of interest to ichthyologists also ix J. Nelson include an appendix list of Darwin’s Fish in Spirits of Wine by Jacqueline McGlade and the list of Beagle specimens in the Natural History (London) and Zoology (Cambridge University) museums. Fishes came into Darwin’s life, just as they do ours, in many fascinating ways, as readers will discover. The book does have lim- its, though, as Professor Pauly has been conservative in his definition of the term ‘fishes’. After all, he could have included us: even we humans are fish derivatives! Darwin receives special respect from biologists. So should fishes. If it were not for fishes we would not have evolved – which cannot be said for finches and other birds. True, Darwin has his detractors, but then so do fishes. Darwin was not the first to suggest that life evolves: such people as his grandfather, Erasmus Darwin, and Jean-Baptiste Lamarck believed life evolved, but we tend to overlook that. What has captivated us is Darwin’s explanation of the driving force of evolution, natural selection. Alfred Russel Wallace had the same explanation for evolution as Darwin, butwetend to overlook that also. One can excuse ichthyologists trying to explain the vast diversity of colour in tropical reef fishes from wondering if something else other than natural selection is at play. But let’s remind the creationists that our knowledge that evolution has occurred, and is still occurring, is not based on the theory of what its driving force(s) may or may not be. Darwin has certainly been a major figure in giving us the impetus to make our classifications reflect evolutionary history. It is through his theory of evolution that we explain similarities between taxa and give a modern rationale to our classifica- tions. Our knowledge of evolution and the historical connections of life with expla- nations of why life is as it is gives biology a unique place among the sciences. In Darwin’s day, about 9000 species of fish were recognized as valid, compared with over 28000 now. We have a concept of species today, as evolutionary lineages sep- arated by irreversible discontinuities (see Nelson 1999), different from that
