The oldest known octopus fossil belongs to an animal that lived some 296 million years ago. By contrast, tool-making, upright humans and been around for about 3 million years, while other primates in our family date back no more than 55 million years. So clearly octopi are ancient and complex beings! Animal behaviorists (ethologists) have long been struck by the intelligent, tool-using behavior of octopi.
