'''Units of selection''' can be any replicator in an [[Evolutionary_System|evolutionary system]]: genes, memes or other replicators which carry information. The units of selection persist across generations. They are often characterized by different scopes and levels, see [[Kin Selection]], [[Group Selection]] and [[Multilevel Selection]], if these levels are influenced by replicators. [[Natural_Selection|Natural selection]] acts on the genotype and selects always something which is replicated. This replicator can be a gene or meme.
