Laughter, a primitive sound more akin to animal calls than speech, signals understanding, agreement, and social bonding.

Humans are not the only animals that laugh; laughter's roots in play and social interaction span across mammals, including rats.

Real laughter differs neurobiologically from posed laughter, revealing deep evolutionary layers of human vocalization and emotion.
