It is necessary to understand how giraffes could have evolved. We came up with Darwin's theory, Lamarckism, and so forth. However, in a manuscript, I classified the species of Giraffa Camelopardalis in light of the heights as an arbitrary principle. Nevertheless, I wrote a paper on classifying Giraffa Camelopardalis species using heights as the reference point. It highlights the evolution of the giraffe posture in light of two characteristics of its postures, namely ephemeral diversity and perpetual diversity. Our theory is based on the concept of provisional height and perpetual height groups of giraffes. Why do giraffes have a long neck? Why do not there be shorter ones? Could also be the question; Are there any groups of giraffes? The origin of the initial height or perpetual height? In Lamarck's discussion of heredity, he gave an imaginary example of how a giraffe stretching its neck to browse leaves high in a tree gradually strengthens and grows a longer neck as a consequence. The non-empirical approach of the theory manifests the following hypothetical testimony: Giraffe posture is a functional function of ephemeral and perpetual diversity.
