These are homologous structures, as they share a common evolutionary origin despite having different functions in each organism. The similarities in bone structure among these different species suggest a common ancestor with similar limbs, which have been adapted for different purposes over time. This provides evidence for evolution by demonstrating how shared characteristics can be modified and specialized in different ways in response to environmental pressures.
