We have so much in common with our cousins, the chimps. Think about this. Have you ever had someone groom you as a chimp might groom another chimp? It feels really good and is quite soothing yet because we are mostly ignorant to our nature no one has ever really unearthed the whole grooming for comfort thing. But they have gotten to the gestures thing:

As they reveal today in the U.S. journal Proceedings of the National Academy of Sciences (PNAS) the pair found that the use of gestures is highly flexible, complex, and difficult to link to specific contexts. The use of gestures even varied widely between different groups of chimps and bonobos.

“The way they use gestures is extremely variable, especially compared with other forms of communication,” said de Waal. “This makes gesture a possible candidate for symbolic communication in our shared ancestor.”

Pretty cool story

Meanwhile, here is my favorite gesture:
