Detailed explanation-1: -In divergent evolution, homologous structures are structures indicating a species is diverging from its ancestor. These structures need not have the same function as those of the species’ ancestors. For example, the forelimbs of humans and bats are homologous structures.

Detailed explanation-2: -Thus, divergent evolution might lead to formation of homologous structures as is in the case of forelimbs of mammals. Thus, homologous structures are organs or bones showing functional diversity but similar anatomical features indicating a shared common ancestry resulting from divergent evolution.

Detailed explanation-3: -Homologies are the result of divergent evolution. Divergent evolution is the process in which organisms from the same common ancestor evolve and accumulate differences, often resulting in a new species.

Detailed explanation-4: -Homologous structures are evidence for divergent evolution because, although the structures are very similar, they can function very differently in each species.
