Kissing transcends its physical nature & becomes a cherished expression of love & desire, showcased in popular culture through movies & poetry. The portrayal of kissing in various art forms captures our imagination & evokes strong emotions & leaves a lasting impact.
Debate still revolves around whether kissing is an instinctual or a learned behavior in humans. While the majority of cultures practice kissing, exceptions exist due to superstitions or cultural beliefs, raising questions about its origin & universality as an instinct.
While most animals or birds don't engage in kissing as humans do, they display alternative behaviors to convey affection, such as sniffing, touching trunks, or licking each other. These behaviors demonstrate the diverse ways in which animals & birds express care and affection.
Kissing may have originated from the practice of kiss-feeding, or mouth-to-mouth feeding, prevalent among early humans. Eventually kissing evolved into a symbol of love, surpassing its practical origins. It transformed into a gesture that plays a role in human emotions.
Though not scientifically proven yet, kissing is believed to serve a purpose beyond its emotional appeal by allowing people to assess genetic compatibility. MHC genes, activated during a kiss, are part of our immune system & contribute to our natural body scent.
Kissing triggers a range of neurochemical reactions in the brain, leading to pleasurable sensations and emotional experiences. Chemicals like dopamine, oxytocin, and serotonin are released, creating feelings of pleasure, euphoria, and attachment.

Despite centuries of human experience with kissing, there is still much to learn about its intricacies. Scientists continue to delve into the evolutionary, psychological & cultural aspects of kissing, aiming to further understand its significance in human relationships.
