Vedclass · Answer

(A) Convergent evolution results in the development of analogous organs, which perform similar functions but have different evolutionary origins. $(1)$ The forelimbs of whales and bats are homologous organs because they share a common ancestral structural plan (pentadactyl limb) but have adapted for different functions (swimming vs. flying). This is an example of divergent evolution. $(2)$ Flippers of penguins and dolphins are analogous organs as they evolved independently for swimming. $(3)$ Eyes of octopuses and mammals are analogous organs that evolved independently to perform the function of vision. $(4)$ Wings of butterflies and birds are analogous organs that evolved independently for flight. Therefore, the forelimbs of whales and bats represent divergent evolution, not convergent evolution.
