Node Definition:
Connecting point where two adjacent branches join which represents an inferred ancestor of extant taxa.
Essential Bioinformatics by Jin Xiong
Node Notes:
In a phylogenetic tree, the starting point of branch at which more than one branches meet and the ending point of branch i.e., the tip of branch termed as the node. The starting point known as internal node which represents the ancestor whereas the tips are known as external node which represents the taxa. The node is also known as taxonomic unit.
