Fins into Limbs

Fins into Limbs PDF Author: Brian K. Hall
Publisher: University of Chicago Press
ISBN: 0226313409
Category : Science
Languages : en
Pages : 461

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 PDF 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.
