Question

a bats wing is used for flight while a monkey uses its hand to grasp objects. these structures have different functions, but on an anatomical level, they have a very similar bone structure. darwin used this evidence to suggest that bats and monkeys share which commonality?
o common parents
o common fossils
o common mutations
o common ancestors

Explanation:

Darwin used anatomical similarities (similar bone structure) to suggest evolutionary relationships. Homologous structures (same origin, different functions) imply a common ancestor. Common ancestors explain shared anatomical features despite different functions. Mutations are random genetic changes. Fossils are preserved remains. Common parents is an incorrect term (should be common ancestor).

Answer:

common ancestors
