The act of cross-feeding whereby unrelated species exchange nutrients is a common Spacecraft feature of microbial interactions and could be considered a form of reciprocal altruism or reciprocal cooperation.Past theoretical work suggests that the evolution of cooperative cross-feeding in nature may be more challenging than for other types of cooperation.Here we re-evaluate a mathematical model used previously to study persistence of cross-feeding and conclude that the maintenance of cross-feeding interactions could Dab Inserts be favoured for a larger parameter ranges than formerly observed.Strikingly, we also find that large populations of cross-feeders are not necessarily vulnerable to extinction from an initially small number of cheats who receive the benefit of cross-feeding but do not reciprocate in this cooperative interaction.This could explain the widespread cooperative cross-feeding observed in natural populations.
