The homologous structures of a bear include its forelimbs, which share a common evolutionary origin with the forelimbs of other mammals, such as humans and whales. Despite differences in function—like walking, swimming, or grasping—these limbs have similar bone structures, including the humerus, radius, and ulna. This similarity reflects the shared ancestry of these species, illustrating the concept of homologous structures in evolutionary Biology.

Is a human appendix a homologous structure?
The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.http://scienceline.ucsb.edu/getkey.php?key=3246

What does it mean when dinosaurs have homologous structure?
Two samples are said to homologous, in this context, when they are both very similar in structure and shape and more than likely function.
Two species have homologous structures what do these homologous strcutures show about the evolutionary relationship between the two species?
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
