埃利希和Raven（1964）在广泛研究鳞翅目跳蝗寄主利用模式的基础上，提出了昆虫/植物关系的逐步共进化机制。这一机制的审查与昆虫之间的相互作用食草动物和植物共享的生物合成途径生产羟基香豆素及其衍生物。生物化学证据表明，植物中酶的变化会产生新的次生物质，依次是羟基香豆素、线性呋喃香豆素和角形呋喃香豆素。这些物质依次不太适合多食性昆虫，但一些寡食性物种通过行为和生理手段（例如，某些芒蕨属，凤蝶（Papilio polyxenes）。最后，含香豆素植物群体的多样性大于缺乏香豆素的相关群体（例如，伞形科），与含香豆素植物相关的昆虫类群比不含香豆素植物上的相关类群更多样化（例如，斑蝶科和凤蝶科）。这是一致的想法，互惠进化的相互作用，专注于次生植物化学，大大增加了植食性昆虫和植物的有机多样性。
Ehrlich and Raven (1964) proposed a stepwise coevolutionary mechanism for insects/plant relationships based on extensive examination of hostplant usage patterns in rhopaloceran Lepidoptera. This mechanism is examined with respect to the interactions between insect herbivores and plants sharing the biosynthetic pathway for production of hydroxycoumarins and derivatives. Biochemical evidence indicates that enzymatic changes in plants give rise to novel secondary substances-sequentially, hydroxycoumarins, linear furanocoumarins and angular furanocoumarins. These substances are sequentially less suitable to polyphagous insects, yet some oligophagous species have counteradapted to furanocoumarins by both behavioral and physiological means (e.g., certain Agonopterix spp., Papilio polyxenes). Finally, diversity in groups of coumarin-containing plants is greater than in related groups lacking coumarins (e.g., Umbelliferae), and insect groups associated with coumarin-containing plants are more diverse than related groups on plants without coumarins (e.g., Oecophoridae and Papilionidae). This is consistent with the idea that reciprocal evolutionary interactions, focusing on secondary plant chemistry, greatly augment the organic diversity of both herbivorous insects and plants.
