"Nielsen (zoology, U. of Copenhagen) examines the unity of the animal kingdom by tracing the evolution of all the 31 living phyla from their unicellar [sic] ancestor. The second edition incorporates new morphological data and new topic areas from the past decade, including histological/ultrastructural and embryological data, numerical cladistic analyses, DNA sequencing and developmental biology. The book is intended as a supplement to recent textbooks on systematic zoology, for undergraduate and graduate students, and as a reference for professionals in the field."--SciTech Book News"This book is a complete analysis of the evolutionary interrelationships and myriad diversity of the animal kingdom. Using modern phylogenetic reasoning based on characters from an extensive review of morphology, including ultrastructure, and embryology, each phylum is analysed to ascertain its monophyly and hence its ancestral characters. These characters are then used to construct a complete phylogenetic tree of the extant animal phyla. This new edition of Animal Evoluation brings the subject fully up to date with new ideas and emphases, as well as new bibliographic data. It includes new chapters on the use of computer programmes and molecular techniques to create phylogenies and is illustrated throughout with finely detailed line drawings and clear diagrams."--Ethology, Ecology, Evolution
