An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant. Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.

Lineages with sexual reproduction
Most species of multicellular plants, animals and fungi reproduce sexually as do many protists. Therefore, the evolution of the lineages of such species has likely been substantially influenced by sexual interactions. In the fossil record, lineages with the capability for sexual reproduction first appeared about 2.0 billion years ago in the Proterozoic Eon, although a later date, 1.2 billion years ago has also been proposed. Lineages of sexually reproducing eukaryotic organisms may have evolved from a single-celled common ancestor.
