Based on the cladogram, which characteristics are common to amphibians, lemurs, and humans?

Amphibians, lemurs, and humans all have vertebrae, or backbones, and are tetrapods, meaning they belong to a group with four limbs or limbs descended from four-limbed ancestors. Hair is not common to all three because amphibians do not have hair. So the shared characteristics are “tetrapod, vertebrae.”
