{"product_id":"the-evolution-of-developmental-pathways-9780878939169","title":"The Evolution of Developmental Pathways","description":"\u003cp\u003eThe contemporary field of evolutionary developmental biology is still a new subdiscipline of evolutionary biology  but it deals with some very old questions: how shape and form in complex organisms change during evolution. Integral to this subject are developmental genetics and molecular biology  and  increasingly  systematics  paleontology  and population genetics as well. The integration of the latter three subjects into evolutionary developmental biology is still in its early stages  however. A principal aim of this book is to introduce upper-level students and biologists in other disciplines to this field  and to present it within its larger context.  Despite the excitement about \"evo-devo \" it is a field that still lacks a set of formal principles of the sort that  for example  inform and give shape to population genetics and systematics. The second principal purpose of this book  therefore  is to suggest a useful general framework for thinking about developmental evolution. The books organizing concept is that of the genetic pathway  the sequence of requisite genetic and molecular activities that underlie a developmental process. From this perspective  the author explores the nature of the genetic  molecular  and selectional events that alter these pathways  yielding developmental change.  The book is organized into three major sections. The first five chapters deal with the history of the field  the data it employs  and basic ideas that inform current research. The next three chapters are devoted to case studies in developmental evolution  starting with examples of currently favored model systems (e.g.  Drosophila melanogaster) and building outward. Six subsequent chapters address questions and problems in the field and key questions for the future. Three appendices on specialized topics and a glossary complete the book.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45651773128757,"sku":"ByrdShop_0878939164","price":316.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780878939169.jpg?v=1781840259","url":"https:\/\/atxbooks.com\/products\/the-evolution-of-developmental-pathways-9780878939169","provider":"ATX Books","version":"1.0","type":"link"}
