What are some example of a morphological trait homologous?

Homologous morphological traits are features that share a common ancestry, even if they serve different functions in the organisms. For example, the forelimbs of humans, bats, and whales have different adaptations for grasping, flying, and swimming, respectively, but they all share the same underlying bone structure. Another example is the presence of vertebrae in mammals, reptiles, and birds, which reflects their shared evolutionary origin. These traits highlight the evolutionary relationships among different species.
