Non-segmentation allows for evolutionary innovation in body form.

a. True

b. False

Answer: a. True

Explanation: Through evolutionary time, animals have developed more-complex body plans, including true tissues, non-segmentation and bilateral symmetry which is possible as a result of evolutionary innovation--the introduction and progression of novel traits compared to what exists before leading to a more advanced or complex form. Non-segmentation indeed allows for evolutionary innovation in body form.

True.
