Humans will learn how to use third arms within the next 30 years,
Humans could have extra limbs like Dr. Octopus
Scientists at Cambridge University are working on a high-tech extra limb that could give humans extra grabbing power like the 'Spider-Man' villain Dr. Octopus.
It would be strapped onto the body and controlled by small movements in the user's natural arms and legs.
Professor Tamar Makin, at Cambridge, believes that adding limbs could be normal within a generation.
She said: "The technologies are already out there. There are issues to deal with - for example, if you want to be comfortable - but control is the real issue."
The extra limbs can help people with daily tasks such as drinking cups of coffee but boffins are warning that the brain will need to adapt to the additions.
Professor Makin said: "Evolution has not prepared us to use an extra body part - the brain will need to adapt."
