Detailed explanation-1: -Coevolution is a term used to describe the mutual changes in two or more species, usually one following the other, that affect their interactions. Flowering plants (angiosperms) and their pollinators are often used as the classic example of this evolutionary phenomenon.

Detailed explanation-2: -Hummingbird beaks and the long-tubular flowers on some of the plants they pollinate are often used as examples. Charles Darwin described an interesting case of pollinator-flowering plant coevolution in Madagascar: the star orchid, Angraecum sesquipedale, has foot-long spurs, with the nectary at the tip.

Detailed explanation-3: -Answer and Explanation: Symbiotic relationships lead to coevolution by creating reproductive benefits to organisms that optimize their relationship with their symbionts.

Detailed explanation-4: -Coevolution is when two or more species that interact with each other on a regular basis evolve in response to each other’s adaptations. This is how plants and their pollinators have evolved.

Detailed explanation-5: -In fact, species in symbiotic relationships tend to evolve together. This is called coevolution. As one species changes, the other species must also change in order to adapt. Coevolution occurs in flowering plants and the species tha t pollinate them.
