Answer Details

The anatomical evidence usually used in support of the evolutionary relationship among whales, humans, birds, and dogs is the possession of pentadactyl limb. A pentadactyl limb is a limb with five digits, such as the hand of a human, wing of a bird, flipper of a whale, and paw of a dog. This similarity in limb structure suggests that these animals shared a common ancestor at some point in their evolutionary history. This is an example of homology, which is the similarity in structure due to a common ancestry.
