Book Description
Long ago, fish fins evolved into the limbs of land vertebrates and tetrapods. During this transition, some elements of the fin were carried over while new features developed. Lizard limbs, bird wings, and human arms and legs are therefore all evolutionary modifications of the original tetrapod limb. A comprehensive look at the current state of research on fin and limb evolution and development, this volume addresses a wide range of subjects—including growth, structure, maintenance, function, and regeneration. Divided into sections on evolution, development, and transformations, the book begins with a historical introduction to the study of fins and limbs and goes on to consider the evolution of limbs into wings as well as adaptations associated with specialized modes of life, such as digging and burrowing. Fins into Limbs also discusses occasions when evolution appears to have been reversed—in whales, for example, whose front limbs became flippers when they reverted to the water—as well as situations in which limbs are lost, such as in snakes. With contributions from world-renowned researchers, Fins into Limbs will be a font for further investigations in the changing field of evolutionary developmental biology.

BIOLOGY OF CHORDATES
Author: PANDEY, B.N.Publisher: PHI Learning Pvt. Ltd.
ISBN: 9387472140
Category : Science
Languages : en
Pages : 676
Book Description
Based on the integrated and holistic approach, the book systematically and comprehensively covers a general account of taxonomical, morphological, anatomical and physiological features of chordates. The text does not restrict discussion only to a representative genus in each class, but also provides knowledge of other important genera, and gives their general account and comparative features to help students understand animal diversity in the phylum. Besides the type study, the book also deals with the developmental and ecological aspects of the genera discussed. The book is intended to fulfill the curriculum need of B.Sc. Zoology, Life Sciences, Biological Sciences and Animal Sciences as well as M.Sc. Zoology students for their core course on chordata (chordates). Additionally, the students appearing for various competitive examinations and entrance test for postgraduate courses in the related fields will find this book useful. KEY FEATURES Incorporates the topics of modern research such as Fish as Biocontrol Agents, Mimicry in Birds, Nesting and Brooding Behaviour of Birds, and so on. Compares important genera of the class—morphological, anatomical and adaptive features. Well-illustrated coloured diagrams with meticulous details and labelling for clear understanding of anatomy. Important information nested in boxes, points to remember and classification in the form of flow charts add strength to each chapter. Provides a variety of pedagogically arranged interactive exercises for self assessment—from fill in the blanks, true/false statements, give reasons to MCQs.

Fish Evolution and Systematics: Evidence from Spermatozoa
Author: Barrie G. M. JamiesonPublisher: Cambridge University Press
ISBN: 0521413044
Category : Science
Languages : en
Pages : 335
Book Description
In this 1991 book, Professor Jamieson masterfully brings together the literature on fish spermatozoa and voluminous work on the evolutionary history of fishes to provide a detailed synthesis of the two fields of fish spermatology and fish systematics. The author begins by considering invertebrate phyla related to the chordates, and goes through the lower chordates and early fishes to the line leading to amphibians and to highest teleosts. His treatment provides a review of fish systematics based on the classical evidence of gross morphology in a cladistic framework and a critical integration of this with information on the degree to which spermatozoa support of conflict with the various hypotheses of relationship. Additionally, Professor Jamieson is joined by Luke K. -P. Leung to give a review of the principles of biological cryopreservation and of the live preservation of fish gametes.
