A scientific approach to explaining development of the embryo started with Hippocrates in Greece in the 5th century BC. Using the ideas current at that time, he tried to explain development in terms of heat, wetness and solidification. The developmental biology has great surprises. In order to keep away from uncertainty with regard to the approach utilized, the present book entitled “The Developmental Biology-Understanding the Embryological Origin” is the updated literature on embryological studies.

Additional feature of this book includes boxed material with in depth explanation of several pertinent topics to extend the scope and coverage area beyond the primary topics. Developmental biologists find themselves within traditions of inquiry that extend back to the beginnings of human inquisitiveness. We are discovering the mechanisms by which male and female are distinguished, by which left and right are separated, by which caterpillars become butterflies and by which organs are formed. This book will extensively assist students, teachers and academicians to further extend their knowledge beyond the course work and related subject matter but onto the practical application to gain insights of what happening new in the present era of applied science.
