Subtle differences in the echoes caused by sound waves bouncing off of objects allow animals to construct an image of the world around them. Bats and dolphins arenâ??t that closely related but both developed the very specialized trait of echolocation independently; itâ??s a classic example of what scientists call â??convergent evolutionâ?? (another example would be the physical similarities between bat wings and bird wings: analogous shapes arrived at independently).
