Most of the Indian Universities have recognized the importance of cell biology and have incorporated the Cell biology, Molecular biology, Genetics, Evolution and Ecology in their syllabi.
Divided in four parts viz. Cells, Genetics, Evolution, and Ecology, this book contains total 34 well-written and profusely illustrated chapters.
The present book is an indispensable text meeting complete requirements of undergraduate students of zoology besides the graduate and medical students.

The Recent Trends in Chordates is carefully organized and clearly written books emphasize the salient facts of anatomical, histological, embryological, physiological and evolutionary concepts of various facets of chordates. The origin and adaptive radiation of each of the main animal classes having been succinctly described.

A primary aim throughout has been clarity so as to make the text selective and meaningful. It will make itself immediate useful to students. It provides a nucleus around which the teacher can plan a successful course without too much learning on complementary and supplementary readings.

The book contains-chapter and are arranged class wise. Each chapter begins with General characters and classification along with some selected animals. The physiological systems of the typed animals have been described so that the reader can develop his ideas step by step and then have a lucid understanding of their interdependence on another to form an integrated whole the living organs.

The book presents a comprehensive synthesis of mammalian morphology, anatomy, physiology, embryology and origin and evolution. This book provides nucleus around which the teachers can plan a successful course without too much learning on complementary and supplementary readings. Efforts have been made to avoid overburdening the students with information. Many of the omissions are intentional to make the text selective.

The second revised edition of the book contains the reading material in the knight of latest researchers and development in the field. These include origin and evolution of mammals, Aquatic adaptation in Mammals, Dentition, Placentation Development and Classification and affinities etc.

The present revised and second edition of the book has been carefully organised and clearly written to help advance students and other engaged in teaching. The subject matter has been presented in a step by step systematic manner with clear understandable illustrations. It deals with the morphology, anatomy, physiology and embryology of Balanoglossus, Herdmania and Amphioxus. Special emphasized chapters are Hemichordata: characters& classification; Subphylum Urochordata: characters and classification; Amphioxus (branchiostoma); Salpa; Doliolum; Rhabdopleura; Cephalodiscus; Pterobranchia and its affinities; Asexual reproduction in tunicate; Endocrine glands of the Protochordata etc. Efforts have been made to avoid overburdening the students with information. Many of the omissions are intentional to make the text selective.
