Don’t Panic! – Mice Aren’t Actually the Smartest
“Man had always assumed that he was more intelligent than dolphins because he had achieved so much — the wheel, New York, wars and so on — whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man — for precisely the same reasons….In fact there was only one species on the planet more intelligent than dolphins, and they spent a lot of their time in behavioural research laboratories running round inside wheels and conducting frighteningly elegant and subtle experiments on man. The fact that once again man completely misinterpreted this relationship was entirely according to these creatures’ plans.” – Douglas Adams, The Hitchhiker’s Guide to the Galaxy

Put Your Hands Up for Intelligence
Ever wonder why people still “talk with their hands” when they’re on the telephone? We often use hand gestures while speaking even at times when the listener cannot see them. Gestures are processed in the same areas of the brain as speech (think sign language): the left inferior frontal gyrus (Broca’s) and the posterior middle temporal gyrus (Wenicke’s area). Hand movements help us to communicate more efficiently and emphasize certain points of the message 
we are trying to convey to our conversational partners. They’re an indication of our thought process throughout the discussion. Evolutionary insight proposes that the language brain regions, which originally supported the pairing of body language and meaning, have been adapted in humans for spoken language; however, we still don’t know precisely the reason why people gesture, and more interestingly, why some people use gestures more often than others.
