Sentient beings need a brain, right? A nervous system to tell the body what to do in the world. It’s what we know. It’s all we know. But there’s a single-cell slime mold, sans any nervous system, that learns, passes knowledge to other molds, and repairs itself within minutes. No one knows even how to categorize this organism.
It’s been around for millions of years, but we have no idea what it is. Is it an animal? Is it a fungus? It’s capable of memory and adapts its behavior. It solves problems of moving around a labyrinth.
“The blob can navigate without eyes, limbs or wings. When researchers sliced up the organism and sprinkled them in a maze, the blob consolidated into its original form.” And get this: “After introducing the experiment to a new blob and allowing it to merge with another, the new super blob show incredible smarts. ‘Somehow during the merging process, the naive cells learned a behavior for a situation that they themselves had never experienced.'”
