Phylogenetic tree:

  1. A phylogenetic tree, also known as phylogeny, is a diagrammatic representation of how various species, animals, or genes descended from a common ancestor.
  2. A phylogenetic tree can be used to track a species' common ancestors back through evolutionary history.
  3. Morphological, biochemical, behavioral, or molecular traits of species or other categories can be used to construct a phylogenetic tree.
  4. The branches, nodes, and roots are phylogenetic tree components.
  5. Bacteria, Archaea, and Eukarya are the three domains of the global phylogenetic tree.
