chin/ذقن/下巴(Xiàba)

The chin,in the human anatomy, is the lowermost part of the face.

 It is formed by the lower front of the mandible. People show a wide variety of chin structures.

The chin developed as a point of muscular attachment facilitating minute movements of the lips associated with speech.

 In human evolution, the chin is a cladistic apomorphy, partially defining anatomically modern Humans as distinct from archaic forms.
