is important because it tells
how octopuses change their behaviour in
to different stimuli. This process is called "
plasticity". A biologist said the research could help us understand more about human
. He said: "The
of the octopus has similar characteristics to
brains....For this reason [the DNA is] a very
candidate to study to improve our
of the evolution of intelligence." He says the brain structure of octopuses show they are more
to mammals than marine invertebrates.
