Download E-books Volvox: A Search for the Molecular and Genetic Origins of Multicellularity and Cellular Differentiation (Developmental and Cell Biology Series) PDF

By David L. Kirk

The imperative thesis of this e-book is that Volvox and its unicellular and colonial family members offer a totally unequalled chance to discover the proximate and supreme factors underlying the evolution from unicellular ancestors of multicellular organisms with absolutely differentiated mobile varieties. a tremendous section of the ebook is dedicated to reviewing what's recognized concerning the genetic, mobile and molecular foundation of improvement within the such a lot broadly studied species of Volvox: V. cateri, which shows a whole department of work among mortal somatic cells and immortal germ cells. although, this subject has been installed context via first contemplating the ecological stipulations and cytological preconditions that seem to have fostered the evolution of organisms of gradually expanding measurement and with gradually expanding tendency to produce terminally differentiated somatic cells. The ebook concludes via elevating the query of even if the germ-soma dichotomy can have developed by means of related or assorted genetic pathways in numerous species of Volvox.
