A phylogenetic tree refers to a chart or a diagram that shows the evolutionary relationships between different species of living organisms.
The purpose of a phylogenetic tree is to identify relationships between different species and to find common ancestors of the species that share common features or DNA sequences.
A phylogenetic tree can also be used to determine an unknown species by looking for its similarities with the ones that are known.
It is used to identify taxonomy and helps to classify an organism based on its evolutionary history and common ancestors.
