Theory of Provisional and Toxicology, Perpetual Height Property of Giraffe

Background: The purpose of the study is to respond to the toxicology change in the posture of giraffes according to its two kinds of properties in the whole evolutionary process. Why giraffe has a long neck? Why do not have shorter? Are there any groups of giraffes? Who initially possess the interim height or perpetual height? Lamarck's discussion of heredity He gave an imagined illustration of the idea that when giraffes stretch their neck to browse leaves high in a tree, they would strengthen and gradually lengthen their neck. This giraffe would then have offspring with a slightly longer neck. All this was said by Lamarck. The aspects of our study say that "The group of provisional, perpetual heights of giraffes was the classifications of living being giraffes as a part of evolution and the rest reason for its long neck. There were the two groups of living species of giraffe one of them were categorized as a temporary height and the other as perpetual height. The initial stage of existence both possesses the same height but due to their property of Interim height and perpetual height one remains with the long neck but another one may gradually decrease its neck length and do not survive anymore. The whole theory is on the aspect of provisional height and perpetual height group of giraffes which resultant in finding the reason behind the length of the neck of a giraffe
