Answer #1

Sol:

Anatomical characteristic features of foreleg bones of a species with inability to rotate it

The species might have a scapula (Shoulder bone) positioned directly above the humerus and not held in place by clavicle or collar bone.
That means clavicle or collar bone is absent. So rotation is restricted and there is no way to articulate foreleg .
Eg: Elephant.
Generally in these kind of species leg bones have stright shafts and are arranged vertically so that the weight of the animal passes through the length of the bones.
To prevent shearing (tearing)forces at bone junctions,all the joint surfaces are in line with the bone shafts.
