Octopus Intelligence Is Unlike Anything We Know

Could such a different neurology really evolve purely by natural selection acting on random mutations?

The octopus, considered to be separated from us by about 700 million years of evolution, is believed to be the most intelligent invertebrate. It challenges many common assumptions about animal intelligence because it is also a short-lived loner. And we are discovering that its nervous system apparatus for intelligence is also completely different from typical mammal or bird models. Rather than having a centralized nervous system, the octopus’ nervous system is spread throughout its body. Two-thirds of its neurons are not inside its brain.
