Why ants yawn in human manner?

Ants do not yawn in a human manner. While ants may exhibit behaviors that resemble yawning, such as stretching of their mandibles or fluttering of their wings, these are not true yawns. Yawning is a behavior characterized by the opening of the mouth and deep inhalation of air, which is primarily associated with sleepiness and fatigue in humans. True yawning has not been scientifically observed or documented in ants.
