Phylogenetic system of classification is based on

Explanation

Phylogenetic classification is an evolutionary classification based on how a common ancestry was shared. Cladistic classification summarizes the .genetic distance. between all species in this .Phylogenetic tree.. In Cladistic classification characters such as analogous characters (characters shared by a pair organisms due to convergent evolution e.g. wings in sparrows and patagia (wing like structures) in flying squirrels) and homologous characters (characters shared by a fair of organisms, inherited from a common ancestor e.g. wing of sparrows and finches) are taken into consideration Ernst Haeckel introduced the method of representing Phylogeny by .tree. branching diagrams.
