To know more about Comparative Account of Brain in Vertebrates refer the presentation. The human brain weighs approximately 1.40kg. It is made of a mass of nerve tissue. Basically, vertebrates share similarity in structure, that is they are homologous for heart and brains. Almost all vertebrates like reptiles, mammals, birds and amphibians show this character of homology. They have the capability to adapt according the surroundings with their basic needs. It is considered that homology provides the path to ancestry, that is, it gives more evidence about the historical creatures of earth. Comparative anatomy of brain in vertebrates is a huge branch which mainly deals with the comparative study of brain. Homology of forelimbs of human, whale, bat(basically all mammals) shows the similarity in structure but varies in function.
