More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

From the book reviews:
“This volume, edited by Minelli et al., is a timely, invaluable, and extensive overview of advances. … This volume is a significant achievement and provides an outstanding starting point for students interested in any aspect of arthropod evolution, as well as a rich resource in which researchers specializing in particular taxa can situate their work in a broader evolutionary and functional context.” (John True, The Quarterly Review of Biology, Vol. 89 (3), September, 2014)
“The ambitious volume of Minelli and co-editors represents a comprehensive, stimulating and timely review of what is currently known about arthropods. Individual chapters reveal gaps in our knowledge and highlight possible directions for further research. … Minelli et al.’s book should not be neglected by zoologists, and I recommend it to all students, teachers and researchers interested in arthropods.” (Georg Mayer, Journal of Zoological Systematics and Evolutionary Research, Vol. 52 (1), 2014)
“The contents are organized into 18 chapters devoted to morphology, paleontology, phylogeny and developmental biology, and to aspects of physiology and molecular biology. … The layout is aesthetically pleasing; drawings and illustrations … as well as the colour images are of high quality throughout. … it can be highly recommended to anyone interested in any group of arthropods and/or in any aspect of biology.” (Hannelore Hoch, Deutsche Entomologische Zeitschrift, Vol. 60 (2), 2014)
