What are phylogenetic trees used for?
A phylogenetic tree or evolutionary tree is a branching diagram or tree , showing the inferred evolutionary relationships among various biological species.
The taxa joined together in the tree are implied to have descended from a common ancestor.
The tips of a phylogenetic tree can be living organisms or fossils and represent the end or the present in an evolutionary lineage.
Phylogenetic analyses have become central to understanding biodiversity , evolution , ecology and genomes.
