Humans could have wings, tentacles or an extra ARM 'in the next few decades'

The thought of humans having wings, tentacles or an extra arm may all seem rather unlikely. But these scenarios could actually become reality in the next few decades, thanks to leaps in human augmentation. Researchers have already designed a'Third Thumb' controlled by foot movements, which allows the wearer to unscrew a bottle, peel a banana or thread a needle using just one hand. Now, experts believe the thumb is just a first step towards larger, more dramatic additions to the human body. Tamar Makin, a professor of cognitive neuroscience at Cambridge University, said the brain's ability to adapt to an extra limb was'extraordinary'.
