This article philosophically explores the invention of the mouth, considering it as a pivotal evolutionary step that significantly influenced life on Earth. It suggests that the mouth's emergence, about 520 million years ago, marked a profound transition from simpler life forms that absorbed nutrients indiscriminately to more complex beings that actively consume their environment. This shift not only transformed feeding habits but also introduced a range of digestive complications, including gas and reflux, which are humorous yet ironic consequences of such an evolutionary leap.

The author reflects on the dual nature of the mouth as both a miraculous invention and a source of various discomforts, posing a critique of its role in human existence. The article conveys a sense of nostalgia for the simplicity of pre-mouth organisms, contrasting them with the complexity of later life forms that experience emotions such as hunger, desire, and even anxiety, which are linked to the act of eating and consumption. By using humor and vivid imagery, the author engages readers in contemplating how the mouth has shaped not just biology but also psychology.

Overall, the piece is a mix of humor and deep reflection, inviting readers to ponder the fundamental aspects of life that stem from such a simple yet complex organ. It raises questions about our relationship with food and consumption, highlighting that while the mouth is essential for nourishment, it also opens up a cascade of cravings and anxieties that define the human experience, contributing to a continuous cycle of desire and fulfillment.
