paragraph_text: Adaptive benefit
  
  Interpersonal love between a man and woman provides an evolutionary adaptive benefit since it facilitates mating and sexual reproduction. However, some organisms can reproduce asexually without mating. Understanding the adaptive benefit of interpersonal love depends on understanding the adaptive benefit of sexual reproduction as opposed to asexual reproduction. Richard Michod reviewed evidence that love, and consequently sexual reproduction, provides two major adaptive advantages. First, sexual reproduction facilitates repair of damages in the DNA that is passed from parent to progeny (during meiosis, a key stage of the sexual process). Second, a gene in either parent may contain a harmful mutation, but in the progeny produced by sexual reproduction, expression of a harmful mutation introduced by one parent is likely to be masked by expression of the unaffected homologous gene from the other parent.
