This phylogenetic life tree is a graphical representation of the evolutionary relationships between living organisms. This diagrammatic representation depicts how various species evolved from a common ancestor. The phylogenetic tree can also be defined as a two-dimensional graph that shows an organism's evolutionary relationship to other organisms. The "Tree of Life" or "Dendrogram" is another name for the phylogenetic tree. The concept of a phylogenetic tree evolved from an ancient concept of a ladder-like progression of life forms from moderate to powerful. Phylogenetic or phylogeny is derived from the old Greek word for race, origin, or lineage, as shown in this simplified life phylogenetic tree diagram.
