Introduction:

A phylogenetic tree is used to show the history of the evolution of species, genes, and populations. These trees are based on the biochemical attributes, physical structures, and behavior of the genes. To construct such tree, the group of some animals and birds are taken into consideration. It is considered that the traits which arise once or which are lost from the group. For simplicity, we select traits which are present (+) or absent (−).
