Cory states the following argument about the evolution of aardvarks and anteaters."Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument? A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution. B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation. C. The Americas and Africa were once joined together, and animals roamed freely between the two lands. D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.
