phylogenetic tree

Diagram showing the evolutionary interrelations of a group of organisms that usually originated from a shared ancestral form. The ancestor is in the tree trunk; organisms that have arisen from it are placed at the ends of tree branches. The distance of one group from the other groups indicates the degree of relationship; that is, closely related groups are located on branches close to one another. Though phylogenetic trees are speculative, they provide a convenient method for studying phylogenetic relationships and evolution. See also phylogeny.

The HA genes (Figure 1) of the Canadian viruses are most closely related to the cluster III group of American viruses that were first isolated from pigs in 1999 (4) and subsequently from turkeys (7,8), though the HA phylogram topography suggests that these Canadian and related US viruses represent a new, separate cluster (IV) of viruses.
