What is the primary evolutionary advantage of bilateral symmetry in animals?
Correct Answer: Increased mobility and streamlined movement
- Step 1: Understand what bilateral symmetry means. It means the body can be divided into two equal halves on either side of a central line.
- Step 2: Recognize that animals with bilateral symmetry have a front (head) and back (tail) end.
- Step 3: Realize that this body shape helps animals move more efficiently in a straight line.
- Step 4: Note that increased mobility helps animals chase after food (predation) or run away from danger (escape).
- Step 5: Conclude that having a streamlined body shape is beneficial for survival in their environment.
