Answer:

The wish bone or furcula is a forked bone found in birds and some dinosaurs, and is formed by the fusion of the two clavicles.

Explanation:

In birds its primary function is to strengthen the thoracic skeleton to withstand the rigours of flight. Humans do not have a wishbone, but we do have two clavicles, although not fused together. We have no need for a wishbone as we do not fly.
