Question

Why haven't 360-degree rotation joints, like wheels or propellers, evolved in living organisms?

A) Evolution has been unable to discover such forms due to inherent constraints.
B) Rotational joints are structurally weak, limiting their evolutionary feasibility.
C) Physiological and physical challenges, including nutrient transfer and friction, pose barriers.
D) Evolutionary constraints and disadvantages, such as bad maneuverability, discourage their development.

What is mentioned as a key reason why we don't see wheel-like locomotion in various organisms?

A) Evolutionary constraints restricting the development of wheel structures.
B) Physiological challenges like nutrient transfer and friction.
C) Bad maneuverability and difficulties in overcoming obstacles.
D) The presence of more efficient locomotion strategies like fish tails and bird wings.

Answer 1

The transition of vertebrates onto land led to the evolution of different locomotion strategies, such as limbs placed under the body and pendulum-like swinging motion, instead of wheel-like rotation.

Step-by-step explanation:

The reason why we don't see wheel-like locomotion in various organisms is because of the changes in body design that occurred during the transition of vertebrates onto land. The transition of vertebrates onto land led to the evolution of different locomotion strategies, such as limbs placed under the body and pendulum-like swinging motion, instead of wheel-like rotation.

Movement on land presented new challenges for animals adapted to movement in water, and these challenges led to the evolution of different locomotion strategies. Instead of using wheel-like rotation, land-dwelling animals developed adaptations such as limbs placed under their bodies and a more efficient pendulum-like swinging motion for moving over land.
