Question

Example of homologous structure

Answer 1

One example of a homologous structure is the forelimb of vertebrates, such as humans, bats, whales, and birds. Despite their different functions, the bones and basic structures of the forelimbs are similar across these different species. These similarities suggest that these structures are derived from a common ancestor and have been modified over time to suit the specific needs of each species.

Answer 2

Only one

Answer 3

One example of a homologous structure is the pentadactyl limb, also known as the five-fingered limb, found in various vertebrates such as humans, bats, whales, and birds. Despite serving different functions (e.g., grasping, flying, swimming), these limbs share a common skeletal structure with five digits and comparable bones arranged in a similar manner. This similarity suggests that these structures are inherited from a common ancestor and have been modified over time for different purposes in each species.
