Etymology: From φῦλον + γένεια
A phylogenetic tree (also phylogeny or evolutionary tree ) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a rooted phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. Unrooted trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to be known or inferred.
Phylogeny refers to the evolutionary history and relationships among individuals or groups of organisms. These relationships are discovered through genetic, morphological, and biochemical comparisons, often represented visually as a phylogenetic tree or diagram.
