Webmultifurcation In a phylogenetic tree, the occurrence of a split in an ancestral branch into more than two branches at an internal node, because the order in which the progenic … A rooted phylogenetic tree (see two graphics at top) is a directed tree with a unique node — the root — corresponding to the (usually imputed) most recent common ancestor of all the entities at the leaves of the tree. The root node does not have a parent node, but serves as the parent of all other nodes in the tree. The root is therefore a node of degree 2, while other internal nodes have a mini…
