The neat thing about planaria worms is that if you cut them in half, the head half will grow a new tail and the tail half will grow a new head. Now, the interesting thing is that even though you chop off the head and the tail grows a new head, that new head knows everything that the old head knew. And this is a form of proof that the memories and knowledge that were contained in that planaria worm didn’t live in the head. They were somehow living in the entire worm.
