Phylogeny refers to the study of relationships among different groups of organisms and their evolutionary relationship.
The relationship among the organisms can be depicted in the form of a phylogenetic tree.
Working of phylogeny:
The branching pattern in phylogeny explains the common ancestors of the species.
Two species are more related if they have a recent common ancestor while they are less related if they have a less common ancestor. This is referred to as relatedness of the species.
The species of interest are found at the end of the lines known as the tree's branches.
The pattern in which the branches are connected directly correlates to the evolutionary relationship among the species.
These evolutionary relationships are determined based on the shared traits comparing the genetic and anatomical similarities.
