==Lineages with sexual reproduction==

Most species of multicellular [[plants]], [[animal]]s and [[fungus|fungi]] reproduce sexually as do many [[protist]]s. 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,<ref>Otto, Sarah P. (2008).
