The unit of evolution is not the individual, nor the species. It is the gene. Take for example the NEHRUJACKET gene on chromosome 24. This gene—located on the synthetic chromosome that creates Supers—is associated with villainy. Those who express a double-recessive become supervillains, which almost universally ends in destruction of the individual. However the existence of supervillains provides the motivation to maintain a population of heroes, and to justify the (hypothetical but unidentified) organisation responsible for C24. This gene in essence [citation needed] creates its own perpetuation.
