Human beings develop from a single cell, the fertilized egg, just one tenth of a millimeter in diameter, smaller thjan a grain of sand, is amazing. That egg contains all the information to develop into a human being. Though many of the mechanisms are understood, there are still many uncertainties, the growth of developmental biology actually made it easier to understand now. The embryo, he name now given to the structure to which the dividing egg gives rise, has a very long and tedious process to develop full organ systems. 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 Origins" is the updated literature on embryological studies.
