CHIMERA. “The classical representation of a chimera, such as that described in Homer’s Iliad, is a mythical beast bearing the body parts of several different creatures combined into a single animal. The term chimera has a more tangible usage in modern science and medicine, where it indicates organisms comprised of cells from two or more individuals of the same or different species.”
