Explanation:

The transitional fossil record shows the ancestral forms and the descendants thus referred to as the transitional form and thus provides evidence over the changes in the fossil lineages. The transitional forms are seen as falling between the various groups in the term of the anatomy and have a mixture of the characters in terms of outside and the inside of the fossil records. In 1859 Charles darwin published the book on the Origin Of the species and he perceived the lack of the transitional fossils and gave the example of this transnational fossil as the tetrapods, fish birds ad the dinosaurs.
