Primitive life forms tend to be asymmetrical with no body plan, while advanced forms have either radial or bilateral symmetry, which are both detailed body plans. Primitive animals also have a sac-like body plan with no specialized organs for digestion, while advanced animals have a tube within a tube body plan that contains specialized digestive organs for more efficient digestion. Primitive animals have very basic, unsegmented bodies with no appendages, while advanced animals have segmented bodies that allow for specialized limbs and body parts.
