进化理论认为，仅通过互惠共生建立互惠共生所需的条件是高度限制性的，通常需要复杂的稳定机制的进化。剥削，即最初的主机受益于牺牲其共生伙伴和互利演变随后通过权衡，提供了一个可以说是更简单的路线建立互惠共生。在这篇综述中，我们讨论了理论和实验证据支持主机开发的互惠互利的微生物共生体的建立和进化中的作用，包括从现存的和实验进化的共生体的数据。我们的结论是，剥削，而不是互惠共生往往可以解释互惠共生微生物共生的起源。
Evolutionary theory suggests that the conditions required for the establishment of mutualistic symbioses through mutualism alone are highly restrictive, often requiring the evolution of complex stabilising mechanisms. Exploitation, whereby initially the host benefits at the expense of its symbiotic partner and mutual benefits evolve subsequently through trade-offs, offers an arguably simpler route to the establishment of mutualistic symbiosis. In this review, we discuss the theoretical and experimental evidence supporting a role for host exploitation in the establishment and evolution of mutualistic microbial symbioses, including data from both extant and experimentally evolved symbioses. We conclude that exploitation rather than mutualism may often explain the origin of mutualistic microbial symbioses.
