Question

Quizplus · Accepted Answer

Homologous structures are structures that have a similar underlying structure or design, but may have different functions. These structures are often shared by organisms in the same line of descent or evolutionary history. For example, the bones in the forelimbs of vertebrates have a similar structure, but different functions (such as wings in birds and bats, arms in humans, and flippers in whales). This similarity suggests that these structures were inherited from a common ancestor and have evolved to have different functions in different lineages.
