Did the gut's nervous system evolve before the brain?
Recent scientific discussions suggest a provocative shift in how we view human anatomy. Researchers propose that the complex network of nerves operating within our digestive tract might actually represent the primary control center, appearing long before the cranial brain took shape. This perspective turns conventional biological assumptions upside down. Instead of viewing the central nervous system as the master organ that dictates bodily functions, experts are exploring whether our mental faculties developed primarily to manage and sustain the metabolic needs of the stomach.
