<u>Answer:</u>

<em>It is advantageous to have  lesser number of bones in the pectoral girdle.</em>

<u>Explanation:</u>

Pectoral girdle is made up by the bones that connect the upper limbs to the appendicular skeleton  which includes all the limb bones. Pectoral girdle in humans is made up of two bones. They are clavicle (collar bone) and scapula. The pectoral girdle allows the free movement of upper limbs.

The bones of pectoral girdle are not as massive as the bones of pelvic girdle since it doesn’t have the function of support. Lesser number of bones in pectoral girdle makes  movement of upper limbs more free.
