This animal phylogenetic tree is a branching diagram or tree that depicts the evolutionary relationships between various biological species or other entities based on physical or genetic similarities and differences. All life on Earth is grouped in a single phylogenetic tree, indicating a common ancestor. Each node with descendants in a rooted phylogenetic tree represents those descendants' inferred most recent common ancestor, and edge lengths in some trees can be interpreted as time estimates. Each node is referred to as a taxonomic unit. Internal nodes are hypothetical taxonomic units because they cannot be observed directly, as shown in this animal phylogenetic tree diagram.
