Question
Which example of similar structures indicates that the species are related?A.Fins of sharks and penguinsB.Forelimbs of bats and dogsC.Webbed feet of frogs and ducksD.Wings of birds and insects
Solution
The example of similar structures that indicates that the species are related is B. Forelimbs of bats and dogs. This is because both bats and dogs are mammals, and their similar forelimb structure is a result of them having a common ancestor. This is an example of homologous structures, which are often used as evidence for evolution and common ancestry.
In contrast, the other options (A, C, and D) are examples of analogous structures, which are similar because they serve the same function, not because they come from a common ancestor. For example, the fins of sharks (which are fish) and penguins (which are birds), the webbed feet of frogs (which are amphibians) and ducks (which are birds), and the wings of birds and insects have evolved independently to serve similar purposes, but these species do not share a recent common ancestor.
