  The descendants of a common ancestor. A branch on a phylogeny.  
     
Any continuous line of descent; any series of organisms connected by reproduction by parent of offspring that are reproductively isolated from other lineages, usually refers to a single evolving species, but may include several species descended from a common ancestor, The term lineage also describe the production of a cell line from a single cell plated in vitro.

An evolutionary lineage (also called a clade) is composed of species, taxa, or individuals that are related by descent from a common ancestor. The concept of an evolutionary lineage is grounded in the science of cladistics. Lineages are often determined by the techniques of molecular systematics.
