Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
