phylogenetic classification system is mainly based on evolutionary relationship between the various organisms this assumes that the organisms belonging to the same taxa have a common ancestor
The evolutionary history of a group of genetically related organisms is called a phylogeny. It includes ancestor species and descendant species. A phylogeny is usually represented by a tree diagram called a phylogenetic tree. An early example of a phylogenetic tree is Darwin’s “Tree of Life” (see Figure below). In this diagram, Darwin was trying to show how he thought evolution had occurred. The tree shows how species evolved through time, from the bottom of the tree to the top. As species evolved, they formed new branches on the tree of life. Some of these species eventually branched into additional descendant species. Others died out, or went extinct, without leaving any descendants
