虽然达尔文在1859年描述了植物 – 传粉者关系中的共同进化过程,但保罗·埃利希和彼得·拉文在1964年的论文“蝴蝶和植物:共同进化研究”中首次引入了“共同进化”一词。在这项研究中,Ehrlich和Raven提出植物会产生有毒化学物质以防止昆虫吃掉它们的叶子,而某些蝴蝶物种则会产生适应性,使它们能够中和毒素并以植物为食。在这种关系中,正在发生进化的军备竞赛,其中每个物种正在对另一物种施加选择性进化压力,影响两个物种的适应性。生态系统或生物群落中生物有机体之间的相互作用决定了特定栖息地中的群落类型。在社区中发展的食物链和食物网有助于推动物种间的共同进化。当物种在环境中争夺资源时,它们会经历自然选择和适应生存的压力。

Although Darwin described the co-evolutionary process in the plant-pollinator relationship in 1859, Paul Ehrlich and Peter Lavin first introduced “co-evolution” in the 1964 paper “Butterflies and Plants: Co-evolution Studies”. The word. In this study, Ehrlich and Raven suggested that plants produce toxic chemicals to prevent insects from eating their leaves, while certain butterfly species produce adaptability that allows them to neutralize toxins and feed on plants. In this relationship, an evolutionary arms race is taking place, in which each species is applying selective evolutionary pressure to another species, affecting the adaptability of the two species. The interactions between biological organisms in ecosystems or biomes determine the type of community in a particular habitat. The food chain and food web developed in the community helps to promote co-evolution between species. When species compete for resources in the environment, they experience the pressure of natural selection and adaptation.
