What are analogous structures and homologous structures?

They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but...

Homologous structures are structures that indicate a related evolutionary ancestry, not just similarity. For example, the flipper of a whale, the wing of a bird, and the arm of a a human are similar...

Homologous structures are two species that have similar structures that can be traced to a common ancestor, while an analogous one does not.

Yes, homologous structures have common bone and muscle structures suggesting that they came from an common ancestor while analogous structures do not share any similarity in features, suggesting that...

Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but...
