Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies).Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). the book celebrated by this colloquium, Systematics and the Origin of Species (1), Ernst Mayr called phenotypic divergence between populations ''the other aspect of speciation.''
