How are advanced and primitive evolutinary forms for the traits of symmetry digestive system and segmentation different?

Answer 1

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.

Answer 2

Advanced evolutionary forms typically exhibit more complexity and specialization in traits like symmetry, digestive system, and segmentation compared to primitive forms. Advanced forms may have more refined symmetrical patterns, a more efficient digestive system specialized for varied diets, and a segmented body plan that allows for better mobility and specialization of body parts. Primitive forms, on the other hand, have simpler versions of these traits that may be less specialized or developed.
