In phylogenetic trees and cladograms, a node signifies a common ancestor where speciation occurred, and the root represents the common ancestor of all species.
Em árvores filogenéticas e cladogramas, um nó representa um ancestral comum onde ocorreu a especiação, e a raiz representa o ancestral comum de todas as espécies.
