Although the single-celled slime mold *Physarum polycephalum* lacks a brain or nervous system, it exhibits a form of primitive intelligence. In experiments, researchers have observed the organism navigating complex mazes to locate food sources, choosing the shortest path with remarkable efficiency. To achieve this, the slime mold leaves behind a trail of extracellular slime as it explores. Upon encountering its own previous trails, the mold avoids them, using the slime as a spatial memory system to prevent it from wandering into areas it has already searched. This externalized memory system demonstrates that complex problem-solving behaviors do not necessarily require a highly developed central nervous system; rather, the mold relies on a totally cool externalized trick to get around.
