phylogeny

https://doi.org/10.1351/goldbook.14914
Pattern of historical relationships between species or other groups resulting from divergence during evolution.
Notes:
  1. Phylogenetic relationships are shown in diagrams (cladograms, phylogenetic trees, evolutionary trees).
  2. Palaeontology is important for understanding phylogeny. Without the fossils of the many groups of organisms now extinct, it could not be understood how present life forms are interrelated.
  3. Phylogenetics, the science of phylogeny, is part of the larger field of systematics, also including taxonomy.
