What advantages are there to mammals in possessing a flexible connection between the pectoral girdle and vertebral column?

Answer 1

Hint : It allows free movement of the rib cage of the mammal; the flexible suspension enables the animal to withstand the shock sustained by the forelimbs when it lands at the end of a jump; the forelimbs possess a wide range of movement, which is useful for such activities as climbing, cleaning the face, manipulating food and digging.
