This human phylogenetic tree is a tree-based model of common ancestry that is a must-have tool for researchers studying biological variation. Phylogenies are particularly useful in studying rapidly evolving populations such as viruses, where the spread of lineages is constantly shaped by the mode of virus transmission, immune system adaptation, and patterns of human migration and contact. These processes may imprint the shapes of virus phylogenies that can be extracted for comparative study; however, as shown in this human phylogenetic tree diagram, tree shapes are inherently difficult to quantify.
