The statement is false because muscle structure variation exists throughout human anatomy, not just in the face. All human muscles show individual variation in size, insertion points, and fiber composition. The face is notable for its complexity and emotional expressiveness, but it is not unique in showing anatomical variation between individuals.

Research has identified 5 basic facial expressions that are universally recognized across cultures: happiness, sadness, anger, fear, and disgust. Some researchers later added surprise as a sixth category, but the classic model identifies 5 core expressions controlled by specific facial muscle groups. The question appears to refer to this established framework of basic emotional expressions.

Research in facial electromyography and anatomical studies shows that genuine (Duchenne) smiles involve both the zygomatic major muscle and the orbicularis oculi muscle around the eyes. Fake (social) smiles typically only activate the zygomatic major, leaving the eye muscles inactive. This muscular difference allows scientists to distinguish authentic from posed expressions.
