How does phylogeny work?

A phylogeny is also called as the evolutionary tree as it represents the evolutionary relationships among a group of organisms called taxa. Phylogeny is discovered through phylogenetic inference methods and mainly used for – Finding the evolution ties between the different organisms and the relationships between the ancestral sequences and descendants. 

The phylogeny is used to study evolutionary biology, including the relationships between various biological species and other entities that are supposed to have a common ancestor of the descendants.

The phylogeny is a diagrammatic representation of evolutionary relationships among organisms. The phylogeny has roots, branches, nodes and tips.

  • The root of the phylogeny represents the ancestral lineage.
  • The branchings on the phylogeny represent the speciation.
  • The tips of the phylogeny represent groups of descendent taxa (often species)
  • The nodes on the phylogeny represent the common ancestors of those descendants.
