Slowly, humans have been finding out that the animals around us are a lot smarter than we thought. The lowly octopus is kind of like an animal genius. Octopi share a common ancestor with humans from 750 million years back: a worm with eye spots. But, while humans keep the brain in one spot, octopi do not. They only have about 500 million neurons, which is 1/20th of what our brains have. The brain of an octopus works like an internet of brains! Their main CPU is only the size of a walnut, but each of their 8 arms carry packets of neurons too.
