In the context of comparative anatomy, the quadrate bone is an element found in the skulls of non-mammalian vertebrates, particularly reptiles and birds. However, in mammalian evolution, the quadrate bone undergoes modification and transformation into the incus bone, which is one of the three small bones in the middle ear responsible for transmitting sound vibrations.
