What do numbers on phylogenetic tree mean?

WebSome trees represent the relationships among major groups of organisms, species, populations, individuals, or even genes. The branches of the tree correspond to ancestor/descendent relationships within a lineage: the part of the branch nearer the base of the tree represents the lineage that is ancestral to the part of the branch nearer the tips. WebThe pattern in which the branches connect represents our understanding of how the species in the tree evolved from a series of common ancestors.
