A Mind of Their Own Scientists discover that octopuses have free-thinking arms

Humans usually think of aliens from outer space when trying to imagine alternative forms of intelligent life. However, there is one animal on Earth that offers a fascinating example of alternative intelligence – the octopus. The animal intelligence of octopuses is comparable to the intelligence of monkeys, dogs, or other problem-solving creatures. Octopuses can build shelters and hunt for food. They are different than other intelligent animals, however, because they are invertebrates.

Most intelligent animals are vertebrates with central nervous systems, but octopuses do not have spinal cords. Instead, only?thirty-three percent of their neurons are in their brains while the remaining neurons live in their arms. This means that octopus arms have a mind of their own. In fact, their arms can act independently, exploring and making choices on their own. Octopuses can control their arms with their brains, but only by focusing specifically upon them.

Nota: existe un documental en Netflix llamado Mi maestro el pulpo, si aún tenemos dudas de que la la inteligencia es dada por un "valor evolutivo" que tenemos los vertebrados, creo que aún seguimos dormidos.
