Which statements describe homologous structures? check all that apply. an example of a homologous structure is the wing of a bird and an insect. an example of a homologous structure is the forelimb of a whale, a human, and a dog. homologous structures have the same function but a different structure. homologous structures have the same structure, but may have a different function. homologous structures indicate a common ancestor. homologous structures do not indicate a common ancestor.

An example of a homologous structure is the forelimb of a whale, a human, and a dog. Homologous structures have the same structure, but may have a different function. Homologous structures indicate a common ancestor. A homologous structure is an organ or bone that's in common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor. This is in contrast to analogous structures where two unrelated animals have structures with similar forms or functions due to convergent evolution. With that in mind, let's look at the available options and see what fits. An example of a homologous structure is the wing of a bird and an insect. * This is an example of an analogous structure, so this is a bad choice. An example of a homologous structure is the forelimb of a whale, a human, and a dog. * Exactly. This is a good example of a homologous structure, so this is a good choice. Homologous structures have the same function but a different structure. * False. This is a type of analogous structure. Homologous structures have the same structure, but may have a different function. * True. A homologous structure is a structure that was present in a common ancestor of different animals. Further evolution may have caused those animals to diverge and the common structure may now be used for different purposes. So this is a good choice. Homologous structures indicate a common ancestor. * Yes, by definition. Homologous structures do not indicate a common ancestor. * Since the previous option was true, this must be false, so a bad choice.

An example of forelimb of a whale, a human, and a dog describes the homologous structure.

Homologous structures have the same structure, but may have a different function.

Homologous structures indicate a common ancestor.

Homologous structures refers to that structure which is similar physical features that share a common ancestor but the physical features do different functions. For example, the limbs of humans, cats, whales, and bats are the homologous structures.

These structure are similar in different organisms but due to different environment they perform different functions so we can conclude that Homologous structures have the same structure, but perform different function.
