Final answer:

The statement suggesting that skeletal organization for movement in vertebrates represents analogous structures is FALSE; they are homologous, evidenced by the appendicular skeleton evolution as vertebrates transitioned from aquatic to terrestrial environments.

Step-by-step explanation:

Skeletal organization relating to limbs used for movement in vertebrates is an example of homologous structures, not analogous structures. This statement is FALSE.

The evolution of the appendicular skeleton as animals moved from water to land involved several key changes. Land animals have their limbs placed under their bodies, which results in each stride requiring less force to move forward and decreases the size of adductor muscles.

The limbs being placed under the body allows for a pendulum-like swing to produce a more efficient stride over land. Moreover, the femur and humerus were rotated to have the ends of limbs pointed forward, aligning with the direction of motion, which is unlike the splayed limb position seen in early tetrapods and fish.
