Résumé:	Dans le monde animal, afin de choisir un père pour leurs petits, les femelles optent en général pour la monogamie : elles sélectionnent le meilleur mâle et en font leur amant. Mais d'autres, très rares, sont capables d'influencer la peternité de leur progéniture tout en ayant... plusieurs partenaires ! Comment ? Une méthode inédite a été découverte chez le grillon provençal, qui arrive à se jouer parfaitement des risques de consanguinité.
