Question

Why is bilateral symmetry considered an evolutionary advantage for active mobility?
Options
A It allows for stationary lifestyles
B It promotes sophisticated predator-prey relationships through directional motion
Correct Answer
C It prevents the formation of an organized nervous system
D It limits the development of tissue layers to only two
Correct Answer

Option B is the correct answer.

Detailed Explanation

Bilateral symmetry allows for streamlined, directional motion, which increases the sophistication of resource-seeking and predator-prey interactions. Radial symmetry is better suited for stationary or limited-motion lifestyles.

Hint

Contrast this with the 'stationary' nature of radial symmetry.
