It is common knowledge that sea creatures like dolphins a high level of intelligence. Scientists have now that octopuses also have "remarkable" intelligence. A team of Italian marine biologists have that octopi have a gene that also the intelligence of humans. The eight-tentacled sea creature short sequences of DNA "jumping genes". These same genes up 45 per cent of the human genome. The researchers said the DNA sequences important for learning and for creating and memories in the brain. The scientists say the DNA may give octopuses cognitive abilities that similar to those humans have.

The scientists say their research findings important as they an insight into how octopuses their behaviour in response to different stimuli. Scientists this process as "behavioural plasticity". Biologist Graziano Fiorito that the research could us understand more about intelligence in humans. He said: "The brain of the octopus functionally analogous in many of its characteristics to that of mammals....For this reason [the DNA] a very interesting candidate to study to our knowledge on the evolution of intelligence." He says the brain structure of octopuses may the creatures are more similar to mammals than invertebrates and other sea life.
