The purpose of this book is to argue, and to convince those who may not agree, that the Hox genes are indeed so important that their study will not end with the 20th century. The book is divided into three major sections. The first section covers aspects of the regulation of Hox gene expression and the structure and function of the now justifiably well-known homeobox. The second sectionoffers insights and discussions of the sometimes contentious issues of the origin and evolution of the aforementioned Hox complexes. In the third and last section the role of the resident loci in the specification of body plans and meristic identity of the arthropods is presented. Devoted to the evolution of Hox genes and Hox complexes, in relation to animal evolution Discusses functionof the Hox genes at the organism level Biological function of the Hox genes in the Bilateria INDICE: Section I.
