This parts of a phylogenetic tree template can be read as an evolutionary history map. A single lineage at the base of many phylogenetic trees represents a common ancestor. Scientists refer to such trees as rooted, which means that all organisms represented in the diagram are related to a single ancestral lineage (typically drawn from the bottom or left). The three domains—Bacteria, Archaea, and Eukarya—diverge from a single point and branch off in the rooted phylogenetic tree. The small branch in this diagram that plants and animals (including humans) occupy demonstrates how recent and minor these groups are compared to other organisms.
