What is a wish bone? Do humans have a wish bone?
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.
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.
