EMBRYOLOGY



Embryology        Embryology is the study of the development of the embryo of an animal. It also provides evidence for the evolution of organisms. For example, if we carefully observe the embryos of vertebrate animals like fish, tortoise, chick, rabbit and man. We will find out that all of them resemble to each other in their initial stages of development to such an extent that it becomes difficult to distinguish them from each other.

       This resemblance of the embryos of different vertebrates indicates that all of these animals have evolved from a common ancestor.
